What Happens When A Dog Dies Of Heart Failure? (Solution)

A dog with congestive heart failure may cough, have trouble breathing, experience fatigue, loss of appetite, or might die suddenly. The heart is then unable to pump enough blood to the body, so fluid backs up, most often into the lungs, causing congestion –– hence the term congestive heart failure.


Is it painful for a dog to die of congestive heart failure?

The dog’s heart can’t pump blood through the body very well. It leads to coughing, exhaustion, a swollen belly — and eventually, the dog’s lungs will fill with fluid, and she will essentially feel as if she is drowning in her own body. We didn’t want Barky to experience a terrifying, painful death.

What are the final stages of heart failure in dogs?

Signs Of A Dog Dying Of Heart Failure

In the event that your dog has just been diagnosed with congestive heart failure, you are likely to be filled with worries about what this implies for their long-term health. CHF is a dangerous illness that cannot be cured, but it may be controlled over time with careful treatment and monitoring. So, how can you tell whether your dog is beginning to suffer as a result of their illness? Our goal with this post is to educate you on canine heart failure and assist you recognize the signs of a dog that is dying from heart failure.

What Is Congestive Heart Failure In Dogs?

Congestive heart failure in dogs is a medical ailment that refers to the heart’s inability to perform its normal functions. The primary job of the heart is to circulate blood throughout the body in order to aid in the performance of important processes. A dog’s heart is unable to perform these functions correctly when the dog has CHF. This results in a variety of issues, all of which have a substantial influence on a dog’s quality of life. The two most prevalent causes of CHF in dogs are mitral valve insufficiency and dilated cardiomyopathy, which are both hereditary conditions.

Canines suffer from a variety of distinct types of heart disease, all of which culminate in either right or left-sided heart failure.

Right-Sided CHF

Blood leaking into the tricuspid valve will occur in a dog suffering from right-sided congestive heart failure. It is likely that this blood will then back up into the dog’s main circulation, resulting in the dog experiencing fluid accumulation. As a result, right-sided CHF is the most prevalent cause of abdominal swelling and peripheral edema, with ascites (an accumulation of fluid in the peritoneal cavity producing abdominal swelling) and peripheral edema following closely behind. That is to say, it is this that contributes to the pot belly appearance of some dogs suffering from heart disease.

Left-Sided CHF

A dog suffering with left-sided CHF will have a buildup of blood in the lungs as a result of the left ventricle’s inability to function properly. This will result in fluid accumulation in the lung tissue, which will result in coughing and other symptoms of respiratory distress. Our canine pals suffer from the most frequent type of heart failure, which is congestive heart failure.

Symptoms Of Congestive Heart Failure In Dogs

The inadequacy of the left ventricle causes a back up of blood in the lungs in a dog suffering from left-sided CHF (cardiomyopathy). Coughing and other types of respiratory discomfort will result as a result of the accumulation of fluid in the lung tissue. Our canine companions are most frequently affected by this type of heart failure.

  • Puffing up their chests all the time
  • Coughing up froth
  • Having difficulty catching their breath
  • Even while in rest, the respiratory rate is elevated
  • After an exercise, you can easily get winded
  • Lethargy
  • sDecrease in appetite
  • sWeakness
  • Gums with a blue tint or muddy color
  • A distended abdomen, collapsing, and passing out

Any of the aforementioned symptoms in your dog should be reported to your veterinarian as soon as possible for further evaluation and care.

What Are The Stages Of Heart Failure In Dogs?

When a veterinarian diagnoses heart failure in a dog, he or she may usually categorize it into four stages: A, B, C, and D.

A is the most severe stage, and C is the least severe. If your dog has heart disease, it is advisable to take him to a veterinarian for an evaluation. However, there are a few methods to categorize your pup’s sickness when he is examined by your veterinarian.

Stage A

The breed of a dog, as well as other medical issues and risk factors, increases the likelihood of the dog developing heart disease. Heart disease symptoms will not be present, and there will be no structural alterations to the heart as a result of their treatment.

Stage B

A dog’s heart murmur is detected during a physical examination, but the canine is not yet displaying signs of the condition. At this stage, there will also be no structural alterations to the heart’s structure.

Stage C

Dogs with heart murmurs, indications of cardiac illness, or even indicators of heart failure are more likely to die than healthy dogs. Even at this level, they may still respond to therapy, and they may frequently be controlled for a short length of time.

Stage D

The dog has been diagnosed with heart failure and is no longer responding to any form of medication. At this time, their symptoms are usually rather severe. Veterinarians commonly refer to stages C and D of heart failure in dogs when discussing the final stages of the disease. Despite the fact that a dog suffering from stage C heart failure may be able to manage the disease if they receive correct care, they will ultimately succumb to the ailment.

Treatment Options For Heart Failure

A physical exam and diagnostic imaging will be used to diagnose your dog’s congestive heart failure, and your veterinarian will discuss a few treatment choices that will allow your dog to live for a longer period of time. Despite the fact that these treatment choices will only provide a band-aid solution for your dog’s heart illness, they will provide them with much-needed comfort as the situation develops. Some of the most frequent treatment options for dogs suffering from congestive heart failure include:


It is possible to use diuretics in conjunction with other cardiac drugs as a therapy option for heart failure. Diuretics are medications that are used to assist regulate the buildup of fluid in the body caused by heart failure.

ACE inhibitors

ACE inhibitors are drugs that assist to widen the blood arteries in the body, reducing the amount of work the heart has to do. They are an effective treatment choice when used in conjunction with other cardiac medications.


Beta-blockers are medications that are used to slow down a dog’s heart rate and keep the dog’s heart rhythm normal. This also results in a decrease in the demand for oxygen, which relieves the heart of further stress.


Dogs’ heart rates are slowed using beta-blockers, which help to keep their heart rhythm regular. This also results in a decrease in the demand for oxygen, which relieves the heart of further strain.

Life Expectancy Of Heart Failure In Dogs

Unfortunately, there is currently no treatment available for canine congestive heart failure. The use of medical treatment can be useful in providing a dog with additional time and making their life more comfortable as their sickness develops. Although there is no known treatment for congestive heart failure, regular medicine and lifestyle adjustments can help patients live longer lives. It is possible that your dog will live anywhere from one to three years if they are identified with heart failure in the early stages.

If, on the other hand, your dog is diagnosed with CHF after exhibiting major symptoms, their time may be shortened significantly. These puppies normally have a life expectancy of 1-6 months, and they will need to be regularly examined for any signs of distress.

Here Are The Signs Of A Dog Dying Of Heart Failure

If your dog is in the late stages of congestive heart failure, you may be wondering about the usual indicators of a dog suffering from CHF in the final stages of the condition. In order to assist you in making the best decision possible for your canine companion, let’s go through some of the indicators of a dog dying from heart failure.

  • Coughing up foam or bloody froth on a regular basis
  • Labored breathing
  • Lethargy
  • Incapacity or unwillingness to exercise
  • Episodes of dizziness
  • Reduced appetite due to distended abdomen Gums that are blue, purple, or muddy in color
  • Constant panting and sighing

What Dog Owners Should Know About Cardiac Arrest and Heart Disease

What happens if your dog has a cardiac attack while you’re away? It’s terrifying to consider the possibility of your dog’s heart abruptly stopping. Although the risk of your dog suffering from cardiac arrest is minimal, it is still a good idea to be familiar with the condition. What to do if your dog goes into cardiac arrest is explained in detail.

What Is Cardiac Arrest in Dogs?

When it comes to “heart attacks,” dogs do not feel them in the same manner that people do. They can, however, suffer from cardiac failure, which can result in the heart stopping completely.

What Is Cardiac Arrest in Dogs?

Heart failure (also known as cardiopulmonary failure) happens when the circulatory and breathing systems stop to operate properly. To put it another way, it signifies that the heart has ceased working. A healthy heart muscle is responsible for pumping oxygenated blood throughout the body. When the heart ceases to pump blood, the body is unable to operate properly. Cardiac arrest is one of the leading causes of mortality. When a dog goes into cardiac arrest, the procedure is quite quick and painless.

All other biological functions will begin to shut down in a short period of time.

The brain and other organs of a dog cannot live for more than four to six minutes if the dog’s brain and other organs are not provided with enough oxygen.

Even if the dog is resuscitated, it is statistically improbable that it will survive for much longer. The likelihood of survival, on the other hand, is frequently determined by the specific reason of cardiac arrest.

Causes of Cardiac Arrest in Dogs

Cardiovascular arrest in dogs can be caused by a variety of different causes. Some of them are medical crises that need rapid veterinarian attention and treatment. Chronic illnesses and even dormant disorders are among the other types of ailments. The result is determined by the degree of the damage to the heart and other organs, as well as the progression of the illness process itself, among other factors.


Heart failure in dogs can be caused by a variety of causes. Some of them are medical crises that need rapid veterinarian attention and intervention. Chronic diseases and even dormant disorders are among the other types of illnesses. This is determined by the extent of damage done to the heart and other organs, as well as how far the illness process has progressed in the first place.

Heart disease

This can result in heart failure, which can eventually lead to cardiac arrest. Some types of heart disease might go undetected for years until they cause abrupt cardiac arrest. The majority of the time, dogs acquire heart disease that worsens over time until they finally die of cardiac arrest. Heart disease can be congenital (existing at birth) or acquired (occurring later in life) (develops over time). When it comes to heart disease in dogs, there are several distinct types to be aware of. Heart disease in senior dogs is a possibility.

The good news is that many forms of heart disease may be controlled medically, allowing patients to live longer lives while also increasing their overall quality of life.

Toxin Exposure

This can have a negative impact on a variety of biological systems and even result in cardiac arrest. Plants, foods, chemicals, and other potentially toxic substances are examples of poisonous substances. Symptoms vary on the type of poison and how much was taken into the body.

Heartworm Disease

If this is left untreated, it will eventually result in cardiac arrest. When an excessive number of adultheartworms infest the dog’s heart, the organ becomes unable to function correctly and eventually fails. It is also possible for as few as one worm to cause mortality by separating from its host and going into the lung tissue. A verminous embolism is the medical term for this condition. In severe cases, lung injury results in insufficient oxygen reaching the heart, which can result in cardiac arrest or other life-threatening complications.

Anesthetic Complications

Although it is rare, cardiac arrest might result as a result of this. Fortunately, most veterinary facilities are equipped with monitoring technology that can detect issues before the heart stops beating completely. The veterinary staff will take the appropriate steps in an attempt to halt the progression of the disease and reawaken the canine. Despite the fact that many dogs will survive anesthesia difficulties, others will not be able to be awakened.


This has the potential to cause the heart to stop unexpectedly. In order to prevent dogs from chewing on electricity cables, it’s vital to store them safely out of the way. Puppies are notorious for chewing on electrical cables.

Cardiovascular arrest can be caused by a variety of different illnesses and ailments. It is possible for any health ailment that cannot be healed or treated to have a significant enough influence on the organs and other body processes that the heart may eventually cease beating.

What to Do If Your Dog Goes Into Cardiac Arrest

If your dog suffers from cardiac arrest, it will be immediately apparent. Your dog will go unconscious and cease to breathe as a result of this. The gums may seem blue or extremely pale depending on the situation. It is possible that the pupils are dilated. If your dog suffers from any of these symptoms, it is critical that you initiate first-aid procedures as quickly as possible. Examine your dog’s respiratory patterns if he appears to be unconscious and not reacting to your attempts to wake him up.

  1. At certain dogs, you may also be able to detect the heartbeat in this region.
  2. If you are unable to detect a heartbeat or pulse in your dog, it is probable that the dog’s heart has stopped.
  3. CPR is best conducted by qualified specialists, but there is no time to spare if someone needs it.
  4. During the intervals between chest compressions, you will need to breathe into your dog’s nose.
  5. You could even want to enroll in a pet first-aid course.
  6. Your dog’s heart might stop beating again at any time if the underlying cause of the cardiac arrest is not discovered.
  7. Make sure you are aware of the location of the nearest open veterinarian clinic at all times.


If you believe your dog is experiencing cardiac arrest, do not hesitate to take him to the nearest veterinarian as quickly as possible. When it comes to saving your dog’s life, the sooner you act the better. Unfortunately, no matter how talented the medical staff is, they will not be able to rescue every dog. If you have any reason to believe your pet is unwell, contact your veterinarian immediately. Always consult your veterinarian for health-related inquiries, since they have evaluated your pet and are familiar with the pet’s medical history, and they can provide the most appropriate suggestions for your pet.

Congestive Heart Failure (CHF) in Dogs

As soon as you suspect your dog is suffering from cardiac arrest, take him to the nearest veterinarian. You have a higher chance of saving your dog’s life the sooner you intervene. Unfortunatley, no matter how talented the medical staff is, not every dog can be rescued. If you have any reason to believe your pet is unwell, contact your veterinarian immediately for advice and treatment.

Always consult your veterinarian for health-related inquiries, since they have evaluated your pet and are familiar with the pet’s medical history, and they can provide the most appropriate suggestions for your pet’s needs and circumstances.

  • The presence of defects in the heart’s walls
  • Fluid accumulation in the sac around the heart
  • Irregular heart rhythm
  • Heartworm illness
  • Elevated blood pressure
  • Endocarditis (infection of the heart valves)
  • Pericarditis (infection of the pericardium). Tumors
  • Pregnancy

Congestive heart failure can occur at any age, in any breed, and in any gender of dog, although it occurs most frequently in dogs between the ages of six and twelve years. Symptoms and Methods of Diagnosis Your dog may not show any indications of congestive heart failure in the early stages of the condition. As the condition advances, the following signs and symptoms may appear:

  • Cushing’s syndrome
  • Difficulty or fast breathing
  • Difficulty exercising
  • Weakness or lethargy (tiredness)
  • Episode of fainting
  • Gums that are gray or blue
  • Abdominal distention, collapse, and sudden death are all possibilities.

It is generally determined by symptoms and physical examination results, in which fluid in the lungs causes the lungs to sound congested when your veterinarian listens with a stethoscope. Congestive heart failure is a medical condition that affects the heart and blood vessels. Vets will often propose a series of tests to definitively diagnose the ailment and pinpoint its etiology, such as those listed below.

  • Blood and urine tests, including a complete blood count (CBC), a biochemical panel, a heartworm test, and a urinalysis are performed. To evaluate the heart, blood vessels, and lungs, radiographs of the chest are taken. An electrocardiogram (ECG)
  • A stress test. An echocardiogram (a noninvasive ultrasound examination of the heart to assess its anatomy and function)
  • The taking of blood pressure measurements

Referral to a veterinary cardiologist may be recommended. Breeds Affected by Congestive Heart Failure While many dog breeds are susceptible to congestive heart failure, Boxers, Doberman Pinschers, and Cocker Spaniels may be genetically predisposed to particular forms of heart failure. Treatment Depending on the circumstances, such as congestive heart failure caused by heartworm disease, therapy of the underlying ailment may be effective in alleviating part or all of the cardiac difficulties. Surgery may be necessary if the problem is caused by a congenital ailment (such as a heart abnormality that has existed since the dog’s birth).

  • Dogs suffering from severe congestive heart failure may require hospitalization and oxygen treatment at the beginning of their illness.
  • A low-sodium diet may also be suggested in order to assist prevent fluid collection in the kidneys.
  • Treatment success and disease progression are often monitored through the use of blood tests, radiography, and ultrasounds.

Signs & Symptoms of End-Stage Canine Congestive Heart Failure

Canine Congestive Heart Failure in the End Stages: Signs and Symptoms Image courtesy of AmyDreves/iStock/Getty Images. Although no one likes to hear the words “congestive heart failure” uttered by a veterinarian, receiving a diagnosis can be advantageous to your dog. Once you and your veterinarian have determined that your beloved animal is suffering from CHF, you and your veterinarian can take actions to help her live longer and feel better. Some dogs can live for a year or more after being diagnosed with CHF if they receive proper treatment.

Understanding the phases of canine congestive heart failure will allow you to be of more assistance. It is possible to prepare yourself to assist your dog through every stage of her sickness if you understand how her disease will proceed.

Your dog will retain fluid

As your dog’s heart muscle weakens and begins to pump less efficiently, fluid will begin to collect in his or her system. During the early stages of CHF, this fluid would most likely pool in his stomach, causing it to enlarge and become painful. Over time, fluid may begin to accumulate in his legs, causing swelling in those areas as well. Fluid will eventually accumulate in your dog’s lungs, making it harder for him to breathe. Even while he’s sleeping, you could notice that he pants or struggles for breath.

At this stage of CHF, your veterinarian would most likely limit the amount of salt in your dog’s diet and prescribe a diuretic to assist your pooch flush out extra water from his system.

This technique involves your veterinarian using a needle to drain some of the fluid from your dog’s stomach in order to make him more comfortable.

Expect appetite changes

As fluid builds up in a dog’s abdomen, it might exert pressure on her stomach, causing her to feel bloated. Some of the medications used to treat congestive heart failure, such as digoxin, can also cause appetite loss. An appetite stimulant may be prescribed by your veterinarian in order to keep her health and strength at their peak. Make some of your dog’s favorite goodies part of the meal as well, and she’ll be more likely to consume her food as a result. This strategy, however, should be used with caution.

Consult with your veterinarian before using this method to ensure that you are making appropriate treat choices.

Unfortunately, a total unwillingness to eat as a dog’s life draws to a close is typical, and it might be a clue that the dog is suffering from congestive heart failure and is dying.

You’ll notice lethargy

As fluid builds up in a dog’s abdomen, it might exert pressure on her stomach, causing her to feel bloated and uncomfortable. It is possible that some of the medications used to treat CHF, such as digoxin, can result in appetite loss. An appetite stimulant may be prescribed by your veterinarian in order to retain her health and strength at their peak. – If you add some of your dog’s favorite goodies with her kibble, you may be able to persuade her into eating more. Although this method is effective, it must be used with caution.

Discuss this technique with your veterinarian first to ensure that you are selecting appropriate treats.

However, even if you are successful in keeping your dog fed, she may ultimately quit eating. The unfortunate reality is that many dogs die from congestive heart failure, which manifests itself as a complete reluctance to eat as their lives come to an end.

You’ll recognize your dog’s congestive heart failure late stages

Despite the fact that you have done an excellent job assisting your dog through her CHF, the very late phases will inevitably arrive. If your dog is still coughing and breathing severely at this stage, he or she should be sent to the vet. While standing or walking, her gums may develop a bluish-gray hue, and she may become dizzy and pass out. The fact that she has difficulty accomplishing anything, even sleeping, is likely to come to your attention. This is especially true for dogs that like to lie on their sides.

As of right now, there isn’t much that can be done to alleviate or manage the symptoms of CHF.

Even though it is difficult, making a person’s death as painless as possible is sometimes the finest present you can provide.

Sudden Cardiac Death – LeadER Vet

Unfortunately, some dogs and cats may succumb to abrupt cardiac death at any time (SCD). Many pet owners who are mourning are left with many unanswered questions and feelings of frustration as a result of this sometimes unexpected catastrophe. A pet’s heart is frequently attributed as the underlying cause of sudden death when the pet is otherwise healthy and has not been exposed to a toxin of any type (such as poison). Cardiac arrhythmias are the most prevalent underlying cause of genuine sudden cardiac death, accounting for almost half of all cases.

  • Pets who suffer from ventricular arrhythmias, such as ventricular tachycardia, may be at risk for abrupt cardiac death.
  • Ventricular fibrillation is fatal unless it is treated immediately with an external defibrillator (a equipment that delivers an electrical shock to the heart to reset the rhythm).
  • Patients at risk for sudden cardiac death as a result of an arrhythmia may or may not exhibit any signs of the condition.
  • To make a definite diagnosis of a cardiac arrhythmia, an EKG (electrocardiogram or ECG) or a Holter monitor (24-hour ambulatory EKG) must be performed or obtained.

Dogs with chronic mitral valvular disease (CMVDz, myxomatous valvular degeneration/MVD, “endocardiosis” – all terms that are interchangeable – can occasionally develop acute congestive heart failure as a result of a rupture of a significant portion of the mitral valve’s supporting structure, resulting in congestive heart failure.

Patients who experience this suddenly develop a significant amount of blood leakage within the heart across the mitral valve, resulting in an abrupt increase in blood pressure in the lungs, rapid fluid accumulation, and death, which may occur relatively quickly as the dog drowns, as the dog drowns quickly.

  1. Some dogs may be able to survive this occurrence, but they will almost always require rigorous hospitalization, oxygen treatment, injectable drugs, and other medical interventions.
  2. It is possible that very minute rips in the muscle will develop over time as a result of the high-velocity jet of mitral regurgitation within the heart striking against the inner lining of the left atrium.
  3. A buildup of blood within the pericardial sac that occurs too quickly prevents blood from adequately filling the right side of the heart, resulting in less blood going into the lungs and oxygen depletion in the bodily tissues.
  4. The use of echocardiography is required for the diagnosis of a ruptured left atrium.
  5. Tumors on the heart have the potential to bleed out unexpectedly, resulting in a sudden death.
  6. Hemorrhage into the pericardial space has the same effect as a ruptured heart chamber in that it limits the capacity of the right side of the heart to fill.
  7. In these cases, prompt pericardiocentesis (also known as “pericardial tap” — manual evacuation of blood from the heart using a specific catheter) is required.
  8. It is more likely that cats may experience heart attacks or clots in their hearts if they have moderate to severe heart chamber enlargement as the result of an underlying heart illness (often hypertrophic cardiomyopathy/HCM).
  9. It is most commonly one or more of the legs that are afflicted, resulting in limping or dragging of the affected leg.
  10. The use of echocardiography is required for the diagnosis of a cardiac clot.
  11. Necropsy (animal autopsy) may provide some answers, however it is a procedure that is rarely used.

If a necropsy is performed in the context of arrhythmias, it may or may not be discovered that the patient has underlying structural heart disease. Fortunately, when sudden cardiac death does occur, it is usually swift and causes little pain. As a result, the suffering is usually minor.

Congestive Heart Failure In Dogs

When the heart is not able to pump enough blood through the body, it is said to be suffering from congestive heart failure (CHF). CHF in dogs can be caused by a variety of factors. The two most typical reasons for this are as follows:

  • Insufficiency of the mitral valve (MVI). MVI is a leaky mitral valve, which is the valve that connects the left atrium to the left ventricle
  • Dilated cardiomyopathy (DCM)
  • And dilated cardiomyopathy (DCM) are all conditions that can occur.

Please refer to the handouts “Dilated Cardiomyopathy in Dogs” and “Mitral Valve Disease in Dogs” for further information on these particular causes of heart disease in dogs. The clinical manifestations of CHF differ depending on whether the dog is suffering from left- or right-sided heart failure, respectively.

What is the difference between right-sided and left-sided CHF?

In patients with right-sided congestive heart failure (RS-CHF), the heart receives insufficient venous blood return to the body. As a result, when the heart contracts or pumps, instead of the right ventricle sending the blood through the lungs for oxygenation, some blood leaks back into the right atrium through the tricuspid valve (the valve that separates the right atrium from the right ventricle). This blood then backs up into the systemic circulation (the main circulation of the body), which gets clogged as a result of the congestion.

  • Ascites is a disorder in which the abdomen becomes swollen with fluid.
  • When the heart contracts or pumps, instead of the left ventricle sending the blood into the systemic circulation, some blood leaks back into the left atrium and subsequently backs up into the lungs in left-sided congestive heart failure (LS-CHF).
  • Coughing and trouble breathing are the result of this.
  • Coughing and fluid in the chest, which are hallmark indications of heart failure, are most usually caused by LS-CHF in most cases.

Is CHF due mainly to heart valve disease?

Coronary artery disease (CAD) is most usually caused by valvular insufficiency. According to current estimates, MVI is responsible for 80 percent of all canine CHF cases. There are a variety of different reasons behind this. CHF can be caused by a variety of factors including disease of the heart muscle (cardiomyopathy), irregular heartbeat, and constriction of several of the major blood arteries. Initial signs and symptoms of MVI include left-sided congestive heart failure. If the heart failure is not addressed, it may worsen to the point where it affects both sides of the heart.

What clinical signs should I expect?

Persistent coughing that is accompanied by difficulty breathing is the most prevalent clinical indication of congestive heart failure (CHF). Most of the time, this is caused by pulmonary edema, which is the buildup of fluid in the lungs. It is also possible that the larger heart would press on the trachea, causing discomfort and a cough to develop.” In patients with congestive heart failure, the most prevalent clinical symptom is continuous coughing followed by difficulties breathing.” Many dogs suffering with CHF become fatigued more easily, have less stamina, and are unable to participate in activities such as playing or walking as they formerly did.

Symptoms of heart failure include coughing when at rest or while sleeping, heavy panting, prolonged loss of appetite, a large tummy, and pale or blue gums, among other things.

Because of the impact of CHF on the dog’s other bodily systems, the dog will have widespread weight loss and muscular atrophy. Any of these indicators should be reported to your veterinarian as soon as they appear in a pet that has a cardiac murmur.

Do dogs have heart attacks?

In humans, a heart attack is typically referred to as myocardial infarction (heart attack) (MI). Myocardial infarction is defined as the loss of cells in a specific section of the heart muscle, or myocardium, of the body. Death of cells occurs most commonly as a result of oxygen deprivation brought on by constriction of the coronary blood arteries, which carry blood to the heart muscle. Cardiac attacks in dogs are extremely rare, although unexpected and sudden death in dogs with any kind of heart disease is a possibility in some cases.

How is CHF diagnosed?

As with any cardiac condition, a number of tests are performed to determine the cause: The first step in diagnosing heart illness is to listen to the heart using a stethoscope, which is known as auscultation. Auscultation is used to identify heart murmurs; the position and strength of the murmur are used to evaluate the importance of the murmur. In order to examine the heart rhythm, and if there are any concerns, the veterinarian may palpate or feel the pulse at the same time to determine its strength and rhythm.

  • In order to determine the size and form of the heart, as well as any abnormalities in the lungs, such as fluid accumulation, a chest X-ray is obtained.
  • Patients suffering from cardiac disease frequently have poor liver and renal function.
  • It is possible to identify and analyze any aberrant heart rhythms (arrhythmias or dysrhythmias).
  • It is possible to measure the size and thickness of each heart chamber, as well as the effectiveness of the heart’s contractions, in real time.

Can’t you treat my dog without these tests?

There are various tests that must be performed in order to diagnose any cardiac disease. The first step in detecting heart illness is auscultation, which involves listening to the heart with a stethoscope. Auscultation is used to identify heart murmurs, and the location and severity of the murmur are used to assess the importance of the finding. In order to examine the heart rhythm, and if there are any concerns, the veterinarian may palpate or feel the pulse at the same time to identify the strength and rhythm.

In order to determine the size and form of the heart, as well as any abnormalities in the lungs, such as fluid accumulation, X-rays are obtained of the chest area.

Patients with cardiac disease frequently have poor liver and renal function.

Any aberrant heart rhythms (arrhythmias or dysrhythmias) can be discovered and assessed with this technology.

Cardiac chamber size and thickness may be measured, and the efficiency of heart contractions can be examined in real time while the heart beats. The efficiency of the heart’s pumping can be determined by several tests.

Congestive Heart Failure in Dogs: Symptoms You Don’t Want to Miss

My dog, Bruiser, was diagnosed with congestive heart failure approximately a month ago and is currently on dialysis. He’s currently on a number of cardiac meds that appear to be working well, as we’ve only noticed a few signs of illness (such as coughing) in the four weeks after he was admitted to our animal emergency hospital’s intensive care unit. As a licensed veterinary technician, I was familiar with the signs and symptoms of canine congestive heart failure. However, until you have observed your dog’s reaction to them, it is impossible to describe them.

In fact, between the ages of 9 and 12 years, 20–25 percent of dogs might be impacted.

According to experts, if CHF is detected early on, the prognosis might be favorable.

This is something that your veterinarian will assist you with.

What is Congestive Heart Failure in Dogs?

“Congestive Heart Failure (CHF) … refers to the heart’s inability to pump adequate blood to the body.” –VCA Hospitals (Victoria and Albert Hospitals) The heart of your dog is a four-chambered pump composed entirely of muscle. The four chambers of the heart are divided by cardiac valves, which guarantee that blood can only travel in one way through the body. Each contraction of the heart muscle moves blood around the body of your dog, giving it with the energy and oxygen it requires while also transporting waste products away from the organs.

Heart disease affects around ten percent of all dogs.

  • Boston Terrier, Cavalier King Charles Spaniel, Chihuahua, Fox Terrier, Miniature Pinscher, Miniature and Toy Poodles, Miniature Schnauzer, Pekingese, Pomeranian, and Whippet are some of the breeds that are represented.

This video goes into further detail on the typical signs and symptoms of heart failure in dogs.

Symptoms of CHF in dogs

The most noticeable indication of Bruiser’s congestive heart failure was laborious breathing. Coughing and trouble breathing are the most prevalent symptoms, which are listed below. Take note of the differences in the symptoms of the early and late stages, and keep a watch out for any of them in your own dog as well. Any of these symptoms should be reported to your veterinarian as soon as they are noticed. Stages in the Early Stages

  • Reduced activity/lethargy
  • Increased sleeping
  • Exercise intolerance
  • Coughing—especially at night or in the early morning
  • Weight loss
  • Diarrhea
  • Fainting episodes
  • And other symptoms

Stages that are late in their development

  • Early stage symptoms include: persistent weight loss, distended belly, vomiting/diarrhea, blue-gray colored gums, leg edema, difficulty breathing, fluid lung sounds, and inability to relax.

Veterinary care is required immediately in a crisis situation, regardless of the ailment.

  • Breathing difficulties
  • Convulsions that last for an extended period of time Uncontrollable vomiting/diarrhea
  • Collapse in the middle of the night Internal or external bleeding that is profuse
  • Crying or wailing because of discomfort

How is CHF diagnosed in dogs?

Bruiser required an echocardiography (heart ultrasound), which indicated degeneration of the mitral heart valve and expansion of the heart as a result of the degenerative process.

An extensive physical examination will be required to ascertain the etiology, as well as whether there is an aberrant heart size, fluid buildup, pleural effusion, or cardiac defects.Steps toward a diagnosis of congestive heart failure in dogs include the following:

  • Examination of the heart using a stethoscope
  • Chest X-rays
  • Blood and urine tests
  • An electrocardiogram are some of the diagnostic procedures used (ECG). In some cases, an ultrasound is performed as well.

Treatment for CHF

The severity of the condition determines the course of treatment. Typically, a number of different medications will be used in the treatment strategy (and supplements).

Heart medication for dogs

  • Diuretics, such as furosemide, are drugs that are used to eliminate excess fluid that has accumulated in the lungs or belly. An inodilator is a class of medications that both increase myocardial contractility and open up constricted blood vessels, thereby reducing the workload on your dog’s already weakened heart. Pimobendan (VETMEDIN) is the only ACE inhibitor now available on the market
  • ACE inhibitors, also known as angiotensin-converting enzyme inhibitors, are a class of drugs that work by relaxing constricted blood arteries.

Bruiser is being treated with Pimobendan, Furosemide, and a medication known as Sprionolactone, which is yet another diuretic.


Dogs with CHF are closely evaluated for symptoms such as lethargy, weakness, collapse, trouble breathing, coughing, and abdominal distension. As previously stated, an increased respiratory rate (RR) is the first sign of fluid accumulation (or pain) in the lungs and serves as a warning sign. The amount of breaths your dog takes in one minute when sleeping or resting is critical to keeping track of your dog’s health. If this number is greater than 40 or is steadily increasing, you should consult your veterinarian immediately for advice.

As a first step, download an app that will assist you in monitoring your dog’s breathing, as this is the most critical signal that your dog is about to fall into heart failure again.

Prognosis for dogs with congestive heart failure

Due to the progressive nature of this condition, new issues and symptoms may manifest themselves in the future. For example, the return of fluid to the lungs might occur, followed by lethargy and a rapid collapse. Bruiser is moving more slowly than he did before being diagnosed. Aside from that, he occasionally gets stomach distress. In general, though, he is doing quite well, and he has recently undergone a check-up with his cardiologist. Fortunately, with appropriate medical care, the vast majority of dogs feel well during treatment and have a high quality of life both during and after treatment.

Heart Attack in Dogs – Symptoms, Causes, Diagnosis, Treatment, Recovery, Management, Cost

My Pam just died an hour ago and I don’t know how or why. My mother informed me that my Pam was still playing with the other dogs when she left our house before she went. She was overjoyed to see me when I arrived at our house, as were all of our five dogs (including her). I took a few steps back and my second dog came up to sit by me. Initially, I was playing all of them at the same time, then Pam took a quick halt and then laid down as if she were dead. I panicked as a result of the shock. It was around 5 p.m.

  • She had vomited the meal she had eaten earlier in the day (dog food).
  • According to reports, I informed my mother about Pam’s ordeal while holding Pam in front of her like a baby, according to the story.
  • She believes she had no control over her actions (shes a good pup).
  • And then she walked out to the yard (which shows she was still able to walk at that point) for no apparent reason, and I began to notice her practically everywhere on our property since I knew something like this would happen (her, dying).
  • I escorted her back inside the home, allowing her to feel my warmth on her skin.
  • I checked her mouth for any further notice so that I could determine whether or not she was still okay.
  • As time went on, I began to believe she was slowly recovering due to the fact that she was producing heat through her own body.

She continued to move.

Consequently, I promptly sat her on the floor to observe what was going on with her, and unfortunately, she appeared to be having a difficult time.

After a while, she was suddenly able to stop her labored breathing.

Afterwards, I flashed a light in her eyes to observe if her pupil continued to dilate, but it was no longer responsive, and her pupil remained continuously large.

I was under the impression that nothing came out of her buttocks.

It wasn’t soft or liquid, but it did have a gritty appearance.

Please, I implore you to respond to my questions: What do you think may have been the cause of her death?

In those 6 hours (5 PM to 1AM), she went from being a joyful energetic pup to being sluggish, vomiting, twitching, passing bloodlike colored feces, and then becoming a nonresponsive pupil (her death). If you ever observe anything like this, please contact me at [email protected] Thanks.

Congestive Heart Failure

CHF occurs when the heart is unable to adequately handle the amount of blood (load) that is delivered to it and pump it out to the rest of the body (thus the name “heart failure”). CHF can be life-threatening. Blood builds up in the vessels of the lungs, causing them to become congested (hence the word “congestive”). This increases the pressure within the vessels. If the fluid is not treated aggressively, it will ultimately seep out into the lungs itself (pulmonary edema), causing breathing difficulties, discomfort, and potentially death if not addressed immediately.

  • Myocardial infarction is a heart failure caused by a condition of the heart’s muscle
  • Dilated cardiomyopathy (DCM) happens when the heart muscle thins and becomes unable to contract effectively, resulting in the heart failing to pump enough blood with each beat. DCM is more commonly found in bigger beed dogs
  • However, it can occur in any breed. When the heart muscle thickens or scars, the condition is known as hypertrophic or restrictive cardiomyopathy. The condition occurs when the heart muscle cannot relax adequately enough to allow for appropriate filling of the heart chambers. Cats are more commonly affected with HCM and RCM. The following conditions can cause myocardial failure in either species: damage to the heart’s muscle caused by drugs and infections (or any other cause)
  • Volume overload – failure caused by a large amount of blood being circulated in the body
  • Disease of the heart’s valves (valvular endocardiosis, endocarditis, or dysplasia), whereby the valves do not close tightly and blood is regurgitated back into the heart with each beat
  • Valvular endo Heart failure caused by systemic disease, such as hyperthyroidism and chronic (long-lasting) anemia
  • Pressure overload – failure caused by the generation of higher than normal pressures within the heart in an attempt to overcome an obstruction to the outflow of blood
  • This can be caused when the outflow of blood is blocked by a blood clot. Heart failure caused by a blood clot can be caused by a blood clot. Periodontal disease (pericarditis) is a type of heart failure that occurs when the sac surrounding the heart (pericardium) or the space created by the pericardium between itself and the heart muscle (pericardial space) becomes infected. Pericarditis generally causes pressure on the heart, preventing it from filling properly and occasionally leading to the collapse of weaker areas (cardiac tamponade). A few instances of pericardial illness include hemorrhage/bleeding into the pericardial space as a result of irregular blood coagulation (for example, rodenticide poisoning), a ruptured tumor on the heart (for example, hemangiosarcoma), and infection of the pericardium.

Dogs and cats of any age and of either sexe are susceptible to the disease. It is possible that owners are unaware that a problem exists before to the onset of congestive failure, or that they are. Because of the pulmonary edema, these animals are typically brought to the veterinarian when their owners observe acute respiratory/breathing problems in their animals. A rise in their respiratory rate and/or effort is evident, typically with a distinct abdomen component to their breathing, and they could or might not have clear, peach-colored fluid coming from their nose or mouth.

The underlying reason, on the other hand, might be extremely difficult to determine.

Valvular disease, shunts, heartworm infection, and cardiac tumors all necessitate the use of more specialized diagnostic procedures.

The treatment of congestive heart failure is primarily focused on clearing the pulmonary edema that is already present as quickly as possible, preventing new edema from accumulating, and supplementing oxygen to the patient during the process, all with the least amount of stress to the patient as is reasonably possible.

It is possible that many dosages will be required.

In some cases, nasal prongs or a nasal canula may be used to give oxygen to the patient instead of an inhaler.

The use of vasodilating medicines (blood pressure lowering agents) such as nitroglycerin ointment or a Nitroprusside infusion may be used as supplementary therapy to reduce the amount of blood returning to the heart and/or the amount of pressure against which the heart needs to pump, respectively.

Once a solid diagnosis of the underlying problem can be made, specific drugs to address the underlying disease process are added to the regimen to help manage the condition.

The prognosis for a patient who arrives with CHF is extremely difficult to predict since the prognosis for the underlying disease processes that may have produced the CHF in the first place varies.

The stress of transporting the animal to the hospital, as well as the first handling, diagnosis, and treatment, may be too much for an animal suffering from advanced and severe pulmonary edema to handle.

In general, animals suffering with CHF are considered to be in serious condition and must be treated quickly.

In order for aggressive therapy to be effective, owners must be completely committed. Animals that are undertreated or badly treated will almost certainly suffer tremendously. Owners should be warned that, depending on the underlying reason, other bouts of CHF may occur.
