How To Check If Your Dog Has Heartworms? (Perfect answer)

A veterinarian uses blood tests to check a dog for heartworms. An antigen test detects specific heartworm proteins, called antigens, which are released by adult female heartworms into the dog’s bloodstream. In most cases, antigen tests can accurately detect infections with one or more adult female heartworms.


What are the first signs of heartworms in dogs?

Early-stage symptoms of heartworm disease

  • Persistent cough. Unlike a regular cough or a kennel cough, which is strong and sporadic, a heartworm- related cough is dry and persistent.

Can you see heartworms in dog poop?

Although many worm types, such as roundworms and tiny hookworms, are shed in your pet’s feces, heartworms do not live in the gastrointestinal (GI) tract, and are not found in feces. The only way to know if your pet has heartworm disease is through a blood test, which detects the presence of adult female worms.

How can I treat my dog for heartworms at home?

Continue to give heartworm preventatives monthly at home. Give the first injection of melarsomine to kill adult heartworms. Restrict exercise and closely monitor for side effects for the next 30 days. Give the second injection of melarsomine 30 days after the first.

5 Signs Your Dog May Have Heartworms

If your pet hasn’t been treated for heartworm disease on a continuous basis, early identification is the next best line of defense. Unfortunately, treating your dog for heartworm disease may be a tough, expensive, and traumatic experience for him. Here are five indicators that your dog may be infected with heartworms.

1. Persistent cough

Instead of the harsh and random cough associated with a typical cough or kennel cough, the dry and chronic cough associated with heartworm infection is more common. Coughing may be triggered by even minor levels of physical activity in the early stages of heartworm infection, when the heartworm parasites make their way into the lungs, causing obstruction and pain.

2. Lethargy

The abrupt loss of interest in going for walks or being active in your pet may be an indication of heartworm infection in your pet. Because of the severity of the disease, your pup may find it difficult to engage in any physical exercise.

3. Weight loss

When heartworm illness begins to develop, it becomes more difficult for dogs to generate the energy necessary to do even the most basic of duties. It is possible that everyday activities such as eating or having a snack will prove to be too exhausting, resulting in fast weight loss.

Middle-stage symptoms of heartworm disease

The heartworms grow and go into the lungs and veins of the host, creating severe obstruction and causing the following symptoms to manifest themselves:

4. Difficulty breathing

In addition to coughing, your dog may experience breathing difficulties that are similar to those associated with an asthma attack.

Also possible is a buildup of fluid around blood vessels in the lungs, making it harder for the lungs to adequately oxygenate the blood.

5. Bulging ribs

It is possible that your dog’s chest will appear to protrude as fluid continues to fill the lungs. As a result of losing weight, the ribs will also seem to bulge outward. This can also be induced by fluid accumulation as a result of the parasite’s existence in the body. Your dog will display extremely evident heartworm signs once the heartworm larvae have fully developed in the heart and lungs of your pet. These symptoms will be followed by long-term consequences for the dog’s health.

Late-stage symptoms of heartworm disease

The same symptoms that you would experience in your pet during the early stages of heartworm illness will be present. These include a lack of appetite, a dry cough, and lethargy. In the latter stages, however, these symptoms will grow more severe, and your pet will begin to have additional difficulties as a result. The following are consistent indications of late-stage heartworm disease:

  • Audible abnormalities within the dog’s lungs
  • An enlarged liver
  • A murmur in the heart

Treating heartworms before they spread

The dog’s lungs are making unusual noises. Hepatosplenomegaly; a murmur in the heart;

7 Signs That Your Dog Has Heartworms

Dogs are natural carriers for heartworms, a parasite that can cause serious health problems in dogs, as well as death in extreme cases. In light of the foregoing, the majority of dog owners are aware that their pet should be treated with heartworm preventive medicine. Getting your dog treated for heartworm illness as soon as possible increases his or her chances of survival by a significant amount. If your dog is on heartworm prevention medicine, it is still vital to identify the indications of heartworm illness so that you may seek treatment as quickly as possible if your pet does become infected with heartworms, which is extremely uncommon.

Warning Symptoms of Heartworms in Dogs

It is regarded as the “silent killer” in dogs since it might take months before your dog exhibits symptoms of heartworm infection in the body. In the early stages of infection, the majority of dogs exhibit little or no symptoms at all, and the more the disease advances, the more probable it is that visible signs will appear. Pay close attention to these warning signs of heartworms in dogs, and take your pet to the veterinarian if any of these symptoms continue.

  1. It is regarded as the “silent killer” in dogs since it might take months before your dog exhibits symptoms of heartworm infection. Early on in the illness, the majority of dogs exhibit little to no signs at all, and the farther the disease advances, the more probable it is that visible signs will appear. Heartworms in dogs can present with a variety of symptoms. If any of these symptoms continue, see your veterinarian.

Diagnosing Heartworms in Dogs

During normal veterinary examinations, we may offer a heartworm test, which involves a short blood sample and identifies the presence of heartworm proteins in the bloodstream. Upon discovering that your dog is infected with heartworms, we will prescribe further testing to establish the best course of treatment.

When Should Dogs Be Tested for Heartworms?

Heartworm testing should be performed on a regular basis at routine vet appointments to ensure that dogs are not infected.

The following is a helpful guideline for when to have your dog’s heartworm testing performed:

  • Due to the fact that it takes a dog 6 months after being infected with heartworms before it tests positive for heartworms, puppies under the age of 6 months can get their first heartworm prevention medicine without first being tested for heartworms. However, you should take your puppy in for heartworm testing again 6 months later, and then once a year after that to ensure that they continue to test negative for heartworms, as described above. Testing for heartworms in adult dogs over the age of 6 months who have not previously received preventative medication should be performed prior to beginning a year-round preventative regimen, followed by testing again six months later and then once a year to ensure continued negative heartworm tests
  • Immediately after your dog’s heartworm prevention has been missed by one or more doses, your dog should be checked for heartworms, and then tested again six months after that.

Even for dogs on year-round heartworm prevention, regular heartworm testing is necessary to ensure that the medicine is functioning properly and effectively. However, even though heartworm medication is normally effective, there is a tiny chance that your dog might become infected owing to conditions such as vomiting the pill or rubbing away the topical medicine. Is your dog displaying signs of heartworm disease? If so, you should consult your veterinarian. You should keep in mind that the sooner we can detect a heartworm infection, the more likely we are to be successful in saving his life.

Heartworm in Dogs – American Heartworm Society

Heartworm-positive dogs are covered in detail in this section.

What is heartworm disease?

Heartworm illness is a dangerous and sometimes deadly disease that affects pets in the United States and many other regions of the world, including several African countries. Pets with this condition suffer from severe lung illness, heart failure, and damage to other organs in the body as a result of the presence of foot-long worms (heartworms) in their hearts, lungs, and related blood vessels. However, heartworm illness is not just limited to canine, feline, and ferret populations; heartworms can also be found in other mammalian species, such as wolves, coyotes, foxes, sea lions, and – in rare cases — humans.

  1. Dogs.
  2. Heartworms that dwell within the dog may develop into adults, mate, and generate children.
  3. Long after the parasites have been removed from the dog’s body, the heartworm illness causes permanent damage to the dog’s heart, lungs, and arteries, resulting in decreased health and quality of life.
  4. Cats.
  5. The cat is an unusual host for heartworms, and the majority of worms that infect cats do not live to reach adulthood.
  6. Heartworm illness in cats is commonly misdiagnosed, which is unfortunate since even juvenile worms may cause significant harm, which manifests itself in the form of a syndrome known as heartworm linked respiratory disease (HARD).

Because the medicine used to treat heartworm infections in dogs cannot be used to treat heartworm infections in cats, the only way to protect cats from the symptoms of heartworm illness is via prevention.

How is heartworm disease transmitted from one pet to another?

The mosquito is a critical player in the life cycle of the heartworm parasite. Infected dogs, foxes, coyotes, and wolves that are infected with adult female heartworms will create minute baby worms known as microfilaria that will circulate in the circulation. Whenever a mosquito bites and draws blood from an infected animal, it picks up these young worms, which mature into “infective stage” larvae over a period of 10 to 14 days after ingesting the blood meal. Afterwards, when the infected mosquito bites another dog, cat, or vulnerable wild animal, the infective larvae are deposited on the animal’s skin and enter the new host through the insect’s bite wound, causing the new host to get the disease.

Heartworms may survive for up to 7 years in dogs and up to 2 or 3 years in cats after they have reached maturity.

What are the signs of heartworm disease in dogs?

The illness manifests itself in many dogs with little or no symptoms in the early stages of the disease. The longer an infection lingers, the more probable it is that symptoms may manifest themselves. Dogs that are active, dogs who have been infected with heartworms, and dogs who have other health issues are more likely to have strong clinical indications. In addition to a mild chronic cough, heartworm illness can manifest itself as a reluctance to engage in physical activity, exhaustion after moderate exertion, a decreased appetite, and weight loss.

Dogs with a high number of heartworms are at risk of developing unexpected obstructions of blood flow inside the heart, which can result in a life-threatening kind of cardiovascular collapse (cardiovascular collapse).

Few dogs survive if the heartworm blockage is not surgically removed as soon as possible.

How significant is my pet’s risk for heartworm infection?

Even if heartworms do not appear to be an issue in your region, there are a number of things to take into consideration. It’s possible that your neighborhood has a higher frequency of heartworm illness than you realize—or that you’ve unwittingly traveled with your pet to a region where heartworms are more prevalent. Heartworm illness is also expanding to new areas of the country on a yearly basis, according to the CDC. Heartworms may be transmitted to humans by stray and neglected dogs, as well as some mammals such as coyotes, wolves, and foxes.

The reality is that heartworm illness has been identified in all 50 states, and it is hard to forecast the risk factors for the condition.

Furthermore, because infected mosquitoes have the ability to enter the house, both outdoor and indoor dogs are at danger.

In order to prevent heartworm infection, the American Heartworm Society suggests that you “think 12:” It is recommended that you (1) have your pet tested for heartworm every 12 months and (2) administer heartworm prevention to your pet for the whole year.

What do I need to know about heartworm testing?

A dangerous and progressive condition, heartworm disease is a parasitic infection. The earlier it is discovered, the greater the odds are that the pet will be rehabilitated. When a dog or cat is infected with heartworms, there are few, if any, early indicators of illness, making it critical to identify their existence with a heartworm test done by a veterinarian. Only a little blood sample from your pet is required for the test, and it works by identifying the presence of heartworm proteins in the blood.

In any situation, results are received in a short period of time.

When should my dog be tested?

There are some differences in the testing processes and time between dogs and cats. Dogs. All dogs should be tested for heartworm infection at least once a year, and this can typically be done at the same time as a normal preventative care appointment. The following are recommendations for testing and scheduling:

  • Heartworm prevention can be started on puppies under 7 months of age without a heartworm test (it takes at least 6 months for a dog to test positive after being infected), but they should be tested 6 months after your initial visit, tested again 6 months later, and tested yearly after that to ensure they are heartworm-free. Adult dogs over the age of 7 months who have not previously been treated with a heartworm preventative medication must be tested prior to beginning heartworm prevention. They, too, must be tested six months and twelve months later, as well as once a year after that. It is recommended that dogs be tested promptly if there has been a lapse in prevention (one or more late or missing doses), then tested again six months later and then yearly after that.

Even when dogs are on heartworm treatment year-round, annual testing is important to confirm that the preventative regimen is effective. Although heartworm treatments are extremely successful, dogs can still become infected with the parasite. Missing even one dosage of a monthly medication—or administering it late—can leave your dog susceptible from infection. Your dog may spit out or vomit a heartworm pill—or rub off a topical medicine—even if you provide the drug according to the instructions.

If you do not get your dog tested, you will not be aware that your dog need therapy.

What happens if my dog tests positive for heartworms?

The discovery that their dog has heartworm is never welcome news, but the good news is that the majority of affected dogs may be effectively treated. In order to do this, it is necessary to first stabilize your dog if he is displaying indications of sickness, followed by the elimination of all adult and immature worms while minimizing the adverse effects of the therapy to a minimum. If your dog tests positive, the following is what you should expect:

  • Confirm the diagnosis with more information. In the event that a dog tests positive on an antigen test, the diagnosis should be verified with a second, and distinct, examination. Exercise should be restricted since the treatment procedure for heartworm is both expensive and complicated, and your veterinarian will want to be absolutely certain that treatment is essential
  • This criteria may be tough to meet, especially if your dog is used to being physically active on a regular basis. However, as soon as the diagnosis is established, your dog’s typical physical activity must be curtailed since physical exertion accelerates the pace at which the heartworms cause damage to the heart and lungs. It is important to reduce your dog’s activity level if his symptoms are severe
  • This will help to stabilize his sickness. It is possible that your dog’s health will need to be stabilized with suitable therapy before true heartworm treatment can begin. It may take many months to complete the therapy in extreme cases of heartworm illness, or when a dog is suffering from another critical ailment
  • Provide the treatment Once your veterinarian has concluded that your dog is stable and suitable for heartworm treatment, he or she will propose a heartworm treatment regimen that includes a number of different phases. The American Heartworm Society has developed guidelines for designing a strategy to combat heartworm infection. Dogs who show no indications or just moderate indicators of heartworm illness, such as coughing or activity intolerance, have a high success rate with heartworm therapy, according to the ASPCA. It is also possible to treat more severe illness successfully, although the risk of consequences is higher. A dog’s degree of heartworm illness does not necessarily correspond to the intensity of his symptoms, and dogs with a large number of worms may have few or no symptoms early in the course of the disease
  • Test (and prevent) for success A heartworm test will be performed by your veterinarian around 6 months after the treatment is done to ensure that all heartworms have been eradicated from the body. You will need to provide heartworm prevention to your dog year-round for the remainder of his life if you want to eliminate the potential of him developing heartworm illness in the future.

More questions about heartworm disease

When you contacted your neighbor this afternoon to inquire if she’d like to go for a stroll over to the dog park — with both of your pets, of course — you were surprised to discover that both your buddy and her dog would be unable to attend due to a scheduling conflict with another event. Following her dog’s heartworm diagnosis, she had just come home from the veterinarian’s office and wanted him to be able to rest and recoup as much as possible. Now that you’ve heard the word, you’re probably wondering what heartworms in dogs are and how they affect them.

Is it possible that her pet has infected yours?

What Are Heartworms in Dogs?

It is a dangerous ailment in which a parasite calledDirofilaria immitistakes up home in your dog’s body, mainly in his heart, lungs, and connected blood vessels, causing him to get ill. Heart failure, lung illness, and maybe even death can result from this syndrome, which can also exacerbate the symptoms of several other disorders. Are you wondering if the heartworms that your dog has are in fact real worms that are residing within his body? Yes, that’s correct. As disgusting as it may sound, these parasites grow from larvae to adult worms over the course of several months.

Depending on the species, they can survive for five to seven years in your dog’s body and develop to be four to six inches long in males and ten to twelve inches long in females, according to the United States Food and Drug Administration (FDA). Take a moment to absorb all of that information!

How Can Your Dog Get Heartworms?

Heartworm illness is transferred when a dog is bitten by an infected mosquito, which leaves behind microfilariae, which develop into larvae and eventually mature into adult heartworms. Following a successful mating with a male heartworm, the adult female releases her children into the dog’s circulation, thereby resuming the life cycle once more. Infected dogs are not infectious, which means your buddy and her dog could have joined you at the dog park if they had wanted to. A dog that is diseased cannot make any other dogs ill simply by being in the same area as them.

Look Out for These Heartworm Symptoms

According to the Food and Drug Administration, there are four phases of heartworm illness, with symptoms differing in each stage. It is possible that you will not notice any symptoms in Class 1, and if you do, it will be a faint cough. Class 2 is the stage at which symptoms begin to develop. You may notice that your dog is more tired after being active, or you may notice that your dog has a cough every now and then. Class 3 symptoms will be more noticeable, and will include a persistent cough as one of its features.

  • When you get a Class 3 diagnosis, you may also experience some difficulty breathing.
  • This occurs when there are so many worms in your dog’s bloodstream that they obstruct the blood flow back to the heart, necessitating rapid surgical intervention.
  • Although not all dogs with heartworm disease progress to this stage, it is critical to determine which type of heartworm illness a dog is suffering from in order to prevent the development of the worst-case scenario in the future.
  • Your dog’s blood will be drawn by the veterinarian in order to determine whether or not he has a heartworm infection.

How Can You Prevent Heartworms?

The good news is that there are treatments available that your dog may use to avoid contracting heartworm disease. Your veterinarian may recommend a topical medication or an oral tablet that should be taken once a month. Keeping your dog safe and healthy means working to prevent heartworms all year long (even if there aren’t any mosquitoes buzzing around in the winter). Make sure you don’t skip a dosage in order to keep your dog safe and healthy. You may never have to worry about your dogs’ health if you practice active prevention, but it’s always a good idea to be on the lookout for any changes in their health.

Also, make an appointment with your veterinarian for your dog’s next examination to discuss heartworm testing and prevention to ensure that your pup remains as healthy as possible throughout his life.

How to Diagnose Heartworms in Dogs: 13 Steps (with Pictures)

You’ve undoubtedly heard that your dog should be treated with a heartworm preventive on a regular basis. The reason for this is that dogs are natural hosts for heartworms, which are parasites that can cause serious health problems in your dog. The circulatory system, the heart, blood vessels, and lungs can all be harmed by heartworms since they dwell inside the blood vessels and in the heart. The importance of prevention and early treatment cannot be overstated. Learn how to tell whether your dog has heartworm disease so that your veterinarian can begin treatment as soon as possible after diagnosis.

  1. 1 Keep an ear out for a cough. At first, you might think that your dog is merely feeling under the weather since you hear him coughing lightly. However, if your dog is suffering from heartworm illness, the dry cough will last longer. You may have noticed your dog coughing intermittently for several weeks.
  • As a result, pay close attention to your dog after you have taken him for a walk
  • Coughing is more evident after activity.
  • 2 Keep a close eye on your dog’s energy level. It’s possible that you’ll notice anything is wrong with your dog’s behavior before you discover he’s suffering from heartworms. After modest exertion, your dog may appear to be overtired, or he may appear to be lagging behind you on a stroll. It is this lack of energy that is an indication of heartworm infection.
  • For example, if your normally lively dog has stopped wanting to go for walks, you should suspect that he is ill.
  • 3 Keep an eye out for your dog’s hunger. Perhaps you’ve noticed that your dog’s appetite has changed. In particular, he will be less interested in food and treats, and he will consume less food overall. Another indication of heartworm infection is weight loss, which is caused by this.
  • As the infection spreads, you may also notice that your dog’s belly grows, despite the fact that he is losing weight. This is due to the fact that fluid fills the abdomen.
  • 4 Keep an eye out for indicators of advanced heartworm infection. If your dog has had heartworms for a long period of time, the symptoms may become more severe. Fainting, collapse, and even death are possible outcomes of these severe symptoms. If your dog exhibits any advanced indications of heartworm infection, send him to the nearest animal emergency hospital as soon as possible.
  • Some dogs may experience abrupt difficulty breathing at the same time as they discharge pee that is brown in color. Furthermore, you may notice that your dog’s gums are pale. These are all symptoms of caval syndrome (a heartworm illness that has progressed to an advanced stage), which is caused by a rapid disintegration of red blood cells.
  • 5 Take into consideration how far along your dog’s heartworm illness has progressed. If your dog is infected with heartworms, his or her symptoms will differ. His symptoms might be non-existent or he could be experiencing breathing difficulty. Because the severity of heartworm disease symptoms can vary from dog to dog, doctors frequently utilize a “three group” method to explain how far along a dog’s heartworm illness has gone. These are the groups:
  • Group I: The infection has been verified, but the dog shows no signs of illness or perhaps a little cough on occasion. This group has the best chance of a successful outcome from therapy. In Group II, the dog coughs a lot and doesn’t like to go for walks
  • When a dog has significant breathing difficulties, fainting episodes, and symptoms of right-heart failure, such as enlarged belly and limbs, it is classified as being in Group III.
  1. 1 Have a physical examination performed. If your dog exhibits any of the heartworm signs listed above, take him to the veterinarian for an examination. During the exam, the veterinarian will use a stethoscope to listen to your dog’s heart rate and rhythm, as well as to his lung sounds. Additionally, the blood of your dog will be checked for heartworm infection.
  • The presence of worms in your dog may not manifest itself in any noticeable changes or symptoms, which is why it is essential to perform an annual blood test on your dog.
  • 2 Carry out more tests. If your dog’s blood test for heartworms comes back positive, your veterinarian may recommend further tests, such as an ECG (which examines the electrical activity of the heart), radiography (which search for heart enlargement), and echocardiogram (which checks for heart enlargement) (which visualizes the heart, the numbers of worms, and the damage done). These assist the veterinarian in determining your dog’s condition, the likelihood of treatment effectiveness, and the dangers associated with treatment.
  • In rare cases, the blood test may come back negative, but the veterinarian may choose to do an echocardiography to see whether there are any worms present. Your dog’s heartworms will be confirmed by a second test if the first test indicates that it has heartworms.
  • 3 Have a second blood test performed. In the case of a dog that is in the early stages of heartworm infection or who only has male worms, the blood test results may be negative (especially since it only tests for proteins given off by female heartworms). If the veterinarian is concerned by a negative result (for example, in a puppy, when there is a higher likelihood of a low worm count), the veterinarian may do a Knott’s test.
  • During a Knott’s test, a sample of blood is spun down and the concentrated sediment is checked for evidence of heartworm infection. Due to the fact that heartworm larvae take many months to grow before they can be detected, it is critical to test dogs twice if they have not been receiving regular heartworm prevention therapy. Each blood test should be performed six to seven months apart to ensure that the heartworm infection is detected.
  • 4 Adhere to the treatment instructions
  • The physician will most likely recommend that you give your dog a heartworm treatment injection to destroy the worms. It is possible that your dog may need to be stabilized and given pain medication. While your dog may have discomfort as a result of the adult worms dying inside the blood vessels, the drug is successful in eradicating heartworms after 1 to 3 months of administering the treatment.
  • Because your dog is most likely feeling poorly at the time of his diagnosis, the veterinarian may decide to stabilize him with cardiac drugs. His circulation will be improved as a result of this prior to therapy.
  1. 1 Become familiar with the heartworm parasite. Infection with heartworms is caused by parasitic worms that dwell in the host’s heart and blood vessels. The number of worms present in a dog’s intestinal tract determines the severity of the infection. Because heartworm infection is a progressive condition, the severity of the infection will worsen over time as the worms reproduce and generate more worms.
  • A dog’s heartworm infection is a contagious illness that has been verified in dogs in all 50 states.
  • 2 Recognize the many ways in which your dog might become sick. Heartworms are spread by the bite of a mosquito, which serves as the host. When an infected mosquito bites a dog and injects heartworm larvae into the dog’s tissue, the dog becomes afflicted with heartworm disease. It takes around 6 months for the larvae to develop and begin reproducing.
  • As a result of the ideal breeding circumstances for mosquitoes in tropical and subtropical locations, heartworm infection is a common occurrence.
  • 3 Have your dog’s heartworms checked for free. Because heartworm symptoms may not manifest themselves for several years, it is critical to frequently test your dog for the parasite (at least once a year, even if your dog is on a regular preventative). The majority of dogs are diagnosed between the ages of two and eight.
  • It is uncommon to find heartworm larvae (microfilaria) in pups under one year of age since the heartworm larvae (microfilaria) grow over a period of 5 to 7 months before producing health concerns.
  • 4 Administer a preventive medication on a monthly basis. Consult your veterinarian to determine what type of monthly preventive you should provide to your dog. The veterinarian will instruct you on how to deliver the medication and what dosage you should provide. Make sure to take your medication on time, no matter which type you pick. The following are examples of preventatives:
  • Oral pills
  • Topical (spot-on) therapies
  • Injections
  • And other methods of therapy

About this article

Summary of the Article XIt is essential to understand the most prevalent signs of heartworm disease in your dog in order to properly diagnose it. Your dog may be suffering from a dry cough that lasts for several weeks. If your cough becomes even more evident after exercising, you might consider seeing your veterinarian. Additionally, your dog may appear overly weary and even fall behind you on walks, which might be an indication of heartworm infection. Another typical symptom of heartworm infection is a lack of interest in food or treats, as well as weight loss.

Not only will your veterinarian examine your dog’s heart and lungs, but he or she will also do a blood test to check for heartworm infection.

A dangerous and sometimes fatal illness that can afflict dogs, cats, and ferrets as well as wild canine species, heartworm disease is spread by the bite of an infected mosquito. Cases of heartworm disease have been documented in all 50 states of the United States, as well as in other countries across the world. Throughout this post, we’ll go over the most frequent signs of heartworm infection in dogs, as well as what you should do next as a pet owner in Boston, Massachusetts.

What is Heartworm Disease?

Heartworm illness is caused by heartworms, which are parasitic worms that live in the human body. The term “heartworm” refers to the fact that they dwell in the heart, more especially the pulmonary artery of the heart, and hence are named as such. These worms can also infiltrate other regions of the heart and lungs, and if left untreated, they can cause serious lung illness, obstructions of the heart’s valves, and damage to other key organs throughout the body. Dogs suffering from severe heart failure may have a bloated belly as a result of fluid accumulation caused by the heart’s inability to adequately pump blood.

  • It is regarded as the “silent killer” in dogs since it might take months before your dog exhibits symptoms of heartworm infection in the body.
  • The eggs laid by adult female heartworms develop into young worms known as microfilaria, which circulate in the bloodstream of the host.
  • The mosquito then develops and matures into the infective larval stage.
  • It takes around six months for the larvae to grow into adult heartworms once they have been introduced into a new host.
  • Heartworms may survive for a long period of time in your pet, and it’s vital to remember that with each new mosquito season comes the possibility of additional heartworm larvae being passed to your canine companion.

An animal is diagnosed with heartworm illness when a blood test is performed, and this test can identify heartworm antibodies in the animal’s blood. A blood smear can also be used to demonstrate the movement of microfilaria in a blood sample on a slide.

What are the Symptoms of Heartworm Disease in Dogs?

Heartworm illness is caused by heartworms, which are parasitic worms that live inside the body of people. For this reason, they are referred to as “heartworms,” as they are found living within the heart itself, more especially in the pulmonary artery. They can also infiltrate other regions of the heart and lungs, and if left untreated, they can cause serious lung illness, obstructions of the heart’s valves, as well as harm to other key organs in the body, including the kidneys. Dogs suffering from severe heart failure may have a large belly as a result of fluid accumulation caused by the heart’s inability to adequately pump blood.

  • It is regarded as the “silent killer” in dogs since it might take months before your dog exhibits symptoms of heartworm infection.
  • Small worms known as microfilaria are produced by adult female heartworms and circulate in the body’s circulation.
  • It is through the bite of an infected mosquito that the infective larvae are transferred to a new host, which is typically a dog, cat, or other animal afflicted with the virus.
  • Dogs may live for five to seven years after they reach maturity, while cats can survive for up to two or three years after they have reached maturity.
  • Veterinary professionals use a blood test to identify heartworm illness, and this test is capable of detecting heartworm antibodies in the blood.

Class 1:

It is possible that your dog will cough if heartworms penetrate the lungs and begin replicating in the lungs and adjacent arteries. This is often characterized by a dry, unproductive cough that becomes more noticeable after activity. Coughing fits in dogs are common, and they can even induce fainting in some cases.

Class 2:

Heartworm illness in dogs manifests itself first as lethargy, which is defined as behaving lethargic and “lazy.” If your dog is refusing to run, hike, or otherwise be as physically active as he typically is, consult your veterinarian about having him examined.

Dogs suffering with heartworm illness frequently appear weak and depleted of energy. This is because the worms are placing an additional burden on the heart and lungs, which can impact energy levels as well as the transport of oxygen throughout the body.

Weight Loss, No Appetite

In addition, as the heartworm illness progresses, your dog may become less hungry, and you may observe some weight loss in your dog. If you see any of these indicators in your pet, schedule an appointment with your local veterinarian as soon as possible to rule out heartworm disease or any other ailments.

Class 3:

The spread of heartworms in your dog’s heart and lungs will make it more difficult for him to move blood and oxygen throughout his body. Additionally, when the heartworms obstruct arteries, fluid will accumulate in the surrounding regions, making it even more difficult for your dog to breathe and obtain oxygen, leading him to take more short, quick breaths.

Distended Abdomen and/or Chest

Dogs with heartworms may have a bloated abdomen or a dilated chest in severe stages of the disease. A condition known as pinched-garden-hose syndrome occurs as a result of the presence of heartworms in the blood vessels of the heart and lungs. As a result, fluid collects in the stomach and tissues surrounding the heart and lungs because it is unable to circulate properly through the heart.

Seizures or Blindness

Heartworms may infiltrate other organs besides the heart, and they have been known to travel to the brain and eyes, causing convulsions and blindness in certain cases. Despite the fact that these symptoms are uncommon in heartworm illness, they should be taken into consideration.

High Blood Pressure

Dogs suffering with heartworm illness may also suffer from high blood pressure, which occurs as a result of the heart having to work harder to pump blood through capillaries that have been partially clogged by the parasite.

Class 4:

As a result of heartworm infection, blood flow is restricted, resulting in a condition known as “vena cava syndrome.” Vena cava syndrome (also known as CS) occurs when heartworms encircle and obstruct the right atrium of the heart, the right ventricle, and the vena cava (the large blood vessel responsible for bringing blood back and forth to the heart). Thus, worms become trapped and interfere with the tricuspid valve’s ability to operate properly, limiting blood flow via this side of the heart and ultimately resulting in heart failure and cardiopulmonary collapse.

It is quite unlikely that anyone will survive at this late stage because the sickness has advanced to such a point.

When Should I Have My Dog Tested for Heartworms?

When it comes to heartworm testing for your dog, you should consult your local veterinarian for suggestions. The American Heartworm Society recommends that dogs be tested for heartworm disease on a regular basis, and they also offer the following recommendations: Puppies under six months of age are eligible to get their first heartworm preventive medicine without having to undergo a heartworm test (because it takes six months for a dog to test positive after being infected). You may get your puppy tested at six months of age, and then every year after that.

If you fail to take your medication on time, your veterinarian may recommend a heartworm test.

If you have any reason to believe that your dog is suffering from heartworm symptoms, you should consult your veterinarian immediately.

The existence of heartworms may be detected with a simple blood draw performed by your veterinarian, and if your dog is infected, your veterinarian can offer suggestions and develop a treatment program for your dog, depending on how sick your dog is.

Signs That Your Dog May Have Heartworms

Heartworm illness in dogs is a regular occurrence. The parasite that causes this sickness has the potential to create serious health problems for your pet. In some severe situations, infected dogs die as a result of the infection. Pets, particularly dogs, must be treated with heartworm prevention medicine at all times, and this is critical. The American Heartworm Society recommends that dog owners take their beloved pets in for heartworm testing every 12 months. Early detection increases your dog’s chances of survival by a factor of ten.

How Can You Tell If Your Dog Has Heartworms?

Dogs are susceptible to heartworm disease. It is possible for your pet’s health to be negatively affected by the parasite that causes this condition. A small number of severe instances result in the death of affected canines. The use of heartworm preventative medicine in pets, particularly dogs, is really essential. Each year, dog owners are advised to take their canine companions in for a heartworm screening test. The sooner your dog is diagnosed, the better his chances of surviving.

Epilepsy, limping, and blindness are some of the other indicators that your dog may have heartworm disease. This generally occurs when the heartworms spread to other regions of the body, such as the brain, where they impair the dog’s ability to move around freely.

When You Should Test Your Dogs for Heartworms

Seizures, lameness, and blindness are all indicators that your dog may be suffering from heartworm. This normally occurs when the heartworms spread to other regions of the body, such as the brain, where they impair the dog’s ability to move around easily.

Heartworm Treatment

Dogs with heartworm illness can make a full recovery if they are caught in the early stages of the disease. In order for the pet to properly recover from parasite infestation, veterinarians must provide a number of treatments. Dislodged heartworms from the lungs and heart may require surgical removal in extreme cases. To avoid your pet going through all of this, do not ignore any of the symptoms listed above and seek medical attention promptly if you suspect a heartworm infection. Don’t forget that prevention is the most effective treatment option for heartworms.

Ok, so here’s the intro text: While the majority of dog owners are familiar with the term “heartworm,” many are not completely aware of the dangers that heartworms can cause to their pets.

Content In adults, heartworms, which are spread by mosquitoes and dwell and grow in your dog’s heart and lungs, can only be discovered after they have been inside your dog for at least four to five months.

If your dog has heartworms, you should consult your veterinarian immediately. Knowing how to spot the symptoms of heartworm disease early will assist you in getting your dog the treatment and care he or she requires more quickly.

What Are the First Signs of Heartworm in Dogs?

Blood tests done by a veterinarian are the most frequent method of diagnosing a heartworm infection in dogs and cats. Heartworms, on the other hand, can be identified by a variety of physical indications, such as:

  • Lethargy or inactivity
  • A decreased appetite that leads to weight loss
  • Coughing
  • Heart failure, blood in the urine, collapsing or fainting are all possible symptoms.


When it comes to heartworms in dogs, one of the most visible signs is a cough. From time to time, you may hear your dog coughing, especially after a vigorous activity session. This can also be a sign of kennel cough, which is a respiratory infection in dogs that is similar to bronchitis. In any case, a trip to the veterinarian will aid in determining which ailment your dog may be suffering from.

Lethargy or inactivity

Take your dog to the veterinarian if his or her activity level or stamina begins to fluctuate. The fact that heartworms have made their way into your dog’s heart means that even the most basic of tasks might be difficult for your companion to do.

Decreased appetite resulting in weight loss

Heartworms grow and travel into the heart and lungs of the dog, causing them to become depressed and lose their appetite. In addition to losing weight, heartworm illness may manifest itself as a symptom.

Heart failure

Heart failure symptoms are more easily identified by a veterinarian than they are by a pet owner in the vast majority of cases. However, you may notice your dog’s pulse become irregular, or their stomach may grow in size when their abdomen fills with fluid as a result of the condition.

Other signs of heartworms in dogs

Because the worms have nearly entirely clogged their hearts, some dogs will have blood in their pee, and others may potentially fall as a result of the infection. Keep in mind that as the heartworms grow, dogs begin to exhibit more evident symptoms, which means that by the time you discover that your dog has heartworms, the illness is likely to be advanced and life-threatening.

What Should You Do If Your Dog Has Heartworms?

The worms will die out as a result of a series of treatments administered by your veterinarian over a period of many months, during which time you must keep your dog quiet and restrict his movement. Given that heartworm treatment may be a tough and time-consuming process for your dog, avoiding heartworm infections is the most efficient method of treating the condition. The best method to protect your dog from this deadly infection is to provide a heartworm prevention medicine to him on a regular basis.
