Is 10 years a good age for a dog?

A 10- to 12-year-old dog, depending on his size and individual variation, is roughly the equivalent of a 60- to 90-year-old person. Though your dog is no longer a young dog, he still needs a good dose of activity to stay healthy, both physically and mentally.

How old is a 7 year old dog?

When you get that number, add 31 and you get the equivalent of the dog’s age in human years. So a 7-year-old dog would be roughly 62.1 human years old.

What is 1 dog years to human years?

As a general guideline, though, the American Veterinary Medical Association breaks it down like this: 15 human years equals the first year of a medium-sized dog’s life. Year two for a dog equals about nine years for a human. And after that, each human year would be approximately five years for a dog.

Is 9 old for a dog?

Although most people think that one human year of age equals seven dog years, it’s not that simple. Small breeds are considered senior dogs around 10-12 years old. Medium size breeds are considered senior dogs around 8-9 years old. Large and giant breeds are considered senior dogs around 6-7 years old.

Is 13 old for a dog?

Physical and Mental Development A 13- to 15-year-old dog, depending on her size and health, is roughly equivalent to a 70- to 115-year-old person. In her elder years, it is harder for your dog to learn new things. Older dogs may find it more difficult or painful to move around.

Why do dogs only live 10 years?

Why not? Like many animal species, the answer lies in how fast they grow and develop. Dogs grow faster than humans, and therefore, their entire lives are accelerated. Humans, for example, don’t start developing teeth until around month 4.

What happens when a dog turns 10?

Be on the lookout for symptoms like excessive thirst, increasing bathroom breaks, weight loss, lack of energy, depression, and increased appetite. While any and all dogs can develop diabetes, some breeds are more susceptible, such as Poodles, Pugs, Miniature Schnauzers, and Samoyeds.

Do dogs slow down at age 10?

By the time your dog hits the age of 10, you may notice that he is starting to slow down. While he still may still want to run and play, and may still be able to do it, he may also be a bit stiff when he rises from sleeping due to developing arthritis and may run out of steam sooner than he used to when he was younger.

Is 16 old for a dog?

A 16-year-old dog, depending on his size, is roughly the equivalent of an 80- to 123-year-old person. Like elderly humans, your dog is moving more slowly and sleeping more than he did in his spryer years. He may be showing signs of cognitive deterioration as well.

Is 11 old for a dog?

A small dog is considered a senior when it hits about 11 years old, a medium-sized dog at 10, and a large dog around eight. At these ages, your canine companion may slow down, gain weight, be forgetful, and experience a dulling of the senses.

Why do dogs age so fast?

Well, dogs are in possession of faster metabolisms and hearts that work harder than our own. Because of all this extra work, dogs age faster and, consequently, live shorter lives. It also means they grow up more quickly. A dog that’s a year old is the equivalent of a human child ready to start school.

How old is the oldest dog?

The greatest reliable age recorded for a dog is 29 years 5 months for an Australian cattle-dog named Bluey, owned by Les Hall of Rochester, Victoria, Australia. Bluey was obtained as a puppy in 1910 and worked among cattle and sheep for nearly 20 years before being put to sleep on 14 November 1939.

Dog Age Chart: Dog Years to Human Years

Body What is the age of your dog in human years? We used to calculate a dog’s age by multiplying it by seven. This computation, on the other hand, is not so straightforward. Check out our dog age calculator and chart to find out how old your dog is. ADVERTISEMENT

The Easy Calculation of Dog’s Age

The simplest method of determining a dog’s age is to take one dog year and multiply it by seven years. This is based on the premise that, on average, dogs live to be approximately 10 years old and people live to be around 70 years old. For example, a dog who is 5 years old is equivalent to 35 “human years.” From a health standpoint, this isn’t a bad path to go because it helps us humans recognize that our dogs aren’t the same as children. Pets require more care and attention as they grow older, and this is especially true for seniors.

Larger breeds are sometimes considered senior when they reach the age of 5 to 6 years.

Visit your veterinarian on a regular basis for checkups; modifications may be made to make your dogs’ lives more pleasant, longer, and healthier.

The More Accurate Calculation of Dog Years

Take one dog year and multiply it by seven years to get a rough estimate of a dog’s age. Dogs live to be roughly 10 years old, while people live to be about 70 years old, according to the assumptions. Consider the age of a 5-year-old dog in terms of “human years.” From a health standpoint, this isn’t a bad approach since it helps us humans recognize that our pets are not the same as our children. Taking additional care and attention for your pet as they get older is a must. The age at which little dogs are deemed “senior” is approximately seven years old in most cases.

Keep an eye out for symptoms such as arthritis and the accompanying discomfort or irritation, weight management problems, vision and hearing problems, and other changes in behavior or activities that might suggest more serious conditions.

  • The first year of a medium-sized dog’s life is equivalent to about 15 years of a human life
  • The second year of a dog’s life is equivalent to approximately nine years of a human life
  • And the third year of a dog’s life is equivalent to approximately 15 years of a human life. After then, every human year is equivalent to around four or five years in a dog’s lifespan.

An average medium-sized dog’s first year of life is equivalent to about 15 years of a human life; an average large dog’s second year of life is equivalent to approximately nine years of a human life; and an average large dog’s life is equivalent to approximately 15 years of a human life. Furthermore, every human year is equivalent to around four or five years in a dog’s life.

How to Calculate Your Dog’s Age

If you have a dog, you’ve probably heard the saying: “One year for Fido is seven years for you.” It turns out that the arithmetic isn’t quite that straightforward. Dogs mature at a faster rate than humans do when we are young. As a result, the first year of your furry friend’s existence is about equivalent to 15 human years. Size and breed are other important considerations. Smaller dogs tend to have longer lives than their bigger counterparts, although they may mature more swiftly in their initial few years of life than larger canines.

Until they reach the age of 10, little and toybred dogs are considered “seniors.” Medium-sized pups fall somewhere in the center of the spectrum in terms of size and temperament.

Clues to Look For

If you’ve acquired a puppy or dog but don’t know anything about their past, it’s possible that you won’t know how old they are. It is possible to estimate their age even if you do not know their birth date. Their teeth should provide you with a general sense of their age. These recommendations will differ from dog to dog, and they will also vary depending on the type of dental treatment (if any) they received prior to coming to you.

  • By 8 weeks, all of the infant teeth have erupted. By 7 months, all permanent teeth have erupted and are white and sparkling
  • By the age of 1-2 years, the teeth have become duller and the rear teeth may have begun to yellow. By the age of three to five years, all teeth may have tartar accumulation and some tooth deterioration. By the age of 5-10 years, the teeth exhibit evidence of wear and illness. By 10-15 years, the teeth are worn down and a significant amount of tartar has accumulated. It is possible that several teeth are missing.

Your veterinarian can also make an educated guess about their age based on a thorough physical examination and tests that examine their bones, joints, muscles, and organs. Senior dogs may exhibit certain distinctive indicators of aging, which are listed below.

  • Cloudy eyes and gray hair are a given. It begins in the area around the snout and subsequently extends to other parts of the face, head, and body
  • Legs that are too stiff
  • Looseskin

Your Dog’s Age In Human Years: A Conversion Chart

It has been widely accepted since the 1950s that 1 dog year is equal to 7 human years for determining how old a dog is “in human years.” This has been the standard computation since the 1950s. However, despite the fact that this formula has been around for an unusually long period, the truth is not quite so straightforward. Despite this, a large number of individuals continue to rely on the old method of calculating. When it comes to dogs, “you can’t really get rid of the seven-year rule,” says Kelly M.

Connor Museumat Washington State University, who organizes data on how long they may live.


According to the Wall Street Journal, it was “a means to educate the public on how quickly a dog matures when compared to a person, mostly from a health aspect.” Bringing in their dogs at least once a year was intended to encourage owners to do so.”

How to Calculate Dog Years to Human Years?

The American Veterinary Medical Association, on the other hand, provides the following broad guidelines:

  • The first year of a medium-sized dog’s life is equivalent to 15 human years
  • A dog’s second year is equivalent to around nine years in a human’s life. Furthermore, each human year would be equivalent to nearly five years for a canine after that.

How Do Researchers Come Up With Those Numbers?

Many aspects must be considered, making it impossible to pinpoint a certain age, however the AVMA states that cats and small dogs are often deemed’senior’ around seven years old, despite the fact that they still have plenty of life remaining in them at that age. The lifespans of large-breed dogs are often shorter than those of smaller breeds, and they are commonly considered senior when they reach the age of 5 to 6 years. Senior pets are classified as such due to the fact that they age at a quicker rate than humans and that vets begin to notice more age-related disorders in these animals as they become older.

The Great Dane is a good illustration of this.

As a result, a 4-year-old Great Dane would be 35 years old in human years at that point.

Dogs are not included in the data collected by the National Center for Health Statistics.

Why Do Smaller Dogs Live Longer than Larger Dogs?

Scientists have been mystified by this phenomena for years, and no explanation has yet been found for the link between a dog’s body mass and its lifetime. Large animals, such as elephants and whales, tend to have longer lives than tiny mammals, such as mice, according to general consensus. So, what is it about little dogs that allows them to live longer lives on average than large breeds? According to researcher Cornelia Kraus, an evolutionary biologist at the University of Göttingen in Germany, who spoke to Inside Science, large dogs age at a faster rate than other animals.

It was discovered that every 4.4 pounds of body mass shortened a dog’s life expectancy by almost one month, according to the researchers.

The exact reason for this is still unknown, though Kraus suggests several possibilities, including that larger dogs may succumb to age-related illnesses sooner and that the accelerated growth of large dogs may result in a higher likelihood of abnormal cell growth and death from cancer.

Canine gerontology is a rapidly growing field of science, as dog owners seek to not only extend the amount of time they spend with their pets, but also to improve the quality of that time spent with their pets.

No matter how old our dogs get, whether measured in human or dog years, there is beauty and charm at every stage of their development and maturation. Senior dogs are particularly endearing and sad, thanks to their gray muzzles and knowledgeable looks.

2019 Epigenetic Clock Study

Researchers at the University of California, San Diego published a study in 2019 that proposed a novel approach for determining the age of a dog that is based on variations in both human and canine DNA throughout time. The addition of methyl groups to DNA molecules occurs in both species over the course of life, modifying the function of DNA without changing the DNA itself. Consequently, scientists have employed DNA methylation to investigate human aging by creating a “epigenetic clock” to track changes in DNA methylation.

It was possible to create an equation for converting dog years to “human years” by multiplying the natural logarithm of a dog’s age by 16 and then adding 31 (human age = 16ln() + 31) as a consequence of the findings.

Due to the fact that the study only featured a single breed, the “human age” of your own dog based on this formula may not exactly match up.

Regardless, the new science-backed method that has been proposed is unquestionably more beneficial for anyone attempting to compute a dog’s “human age” than the long-debunked “multiply by 7” myth that has been around for a while.

Did You Know?

Evidently, humans have been equating human years to canine years for hundreds of years. A prediction for Judgement Day was carved into the floor of Westminster Abbey in 1268 by artisans working on the Cosmati Pavement: “If the reader wisely considers all that is laid down, he will find here the end of the primum mobile; a hedge lives for three years, add dogs and horses and men, stags and ravens, eagles, enormous whales, the world: each one following triples the years of the one before.” According to this equation, a dog can live to nine years old and a man can live to 80 years old.

If these data are correct, between 1268 and the mid-20th century, canines had their lives cut short by a year, while humans lost about a decade.

How Old Is My Dog in Human Years?

Pet owners have been inquiring about the age of their pets in human years for hundreds of years (and probably longer). Our primary motivation for doing so is to guess about how old our dogs would be if they suddenly converted into humans, but there is also a practical benefit to doing so as well. Comparing our dogs’ age to a human counterpart allows us to have a better understanding of their life expectancy, energy levels and the kind of health concerns we may anticipate to encounter. The information gained from this helps us understand what is typical and what symptoms may be out of the usual.

How old is a dog in human years?

Dogs, according to popular opinion, age seven times more quickly than human beings do. Fortunately, the real figure is really significantly lower, which means that our dogs will be able to spend more years with us than they would if the myth were to be true.

However, it is not as simple as their just growing older by the human equivalent of a round number that is easy to recall each year. In reality, dogs mature at varied rates throughout their lives, and their size is a significant influence in deciding how fast they grow.

Dog Size(Average weight for breed) Small(9.5kg) Medium(9.5-22kg) Large(23kg +)
Age of Dog(Years) Equivalent Human Age(Years)

14 72 78 88
15 76 83 93
16 80 87 120

The table above provides a more accurate indication of how old your dog is in human years; but, a less exact but more basic technique may be more to your liking. If this is the case, the usual guideline to follow is that your dog will reach the age of 15 human years in the first year, 9 years in the second year, and 5 years following.

How do you calculate how old a dog is?

The values in the table above are based on a variety of criteria, the majority of which are physical in nature. A 1-year-old dog, for example, is about similar to a 15-year-old teenager in terms of development, strength, and energy, and having reached (or being on the verge of reaching) sexual maturity, according to our calculations. Meanwhile, as dogs grow older, their teeth begin to show signs of wear and tear, and they are more susceptible to diseases and disorders that we identify with the elderly, such as arthritis, clouded eyes, loose skin, and grey hair, among other things.

Age of Dog Human Equivalent Indicator(s)
8 weeks 3-4 years Baby teeth have finished growing
7 months 8-10 years All permanent teeth have grown
1-2 years 15-24 years Teeth starting to yellow and duller
3-5 years 28-36 years Tooth wear and plaque build-up is common
5-10 years 36-66 years Teeth and gums show some signs of disease
10-15 years 56-93 years Teeth well worn, lots of plaque and some may be missing

In spite of this, researchers are still baffled as to why larger kinds of dogs tend to age more quickly than smaller types. As a matter of fact, this is fairly rare among other species, with larger animals (whales, elephants, for example) preferring to have relatively long lives, whilst smaller animals tend to spend shorter lives (rodents, small birds). It is unknown why, but older dogs tend to age considerably more swiftly in their latter years, whilst smaller dogs tend to age more gradually.

Help your dog live a healthy life

Although every dog is unique, and there is nothing we can do to prevent genetic predispositions to sickness, the best approach to ensure that your dog lives the longest possible life is to keep them as healthy as possible, both mentally and physically, as much as possible. The greatest approach to keep your dog happy, engaged, and physically healthy is to provide him with a loving environment filled with plenty of play, attention, and exercise. Meanwhile, a well-balanced diet of foods they enjoy while also providing them with all the nourishment they require will help to maintain their bones and muscles as strong and healthy as they possibly can.

No, a ‘dog year’ isn’t equivalent to 7 human years

Dogs mature at a different rate than humans, but the basic formula of seven dog years to one human year is far from realistic when comparing the two species. In the unlikely event that humans genuinely aged seven times more slowly than dogs, many of us would be able to procreate at the age of seven and live to be 150 years old. Obviously, this isn’t the situation. The reason that dogs can attain full sexual maturity after just one year of birth is that our canine companions age at a quicker rate throughout the first two years of their life than humans do during those first two years.

Dogs age more fast at the beginning of their lives than humans, and they age more slowly near the end of their lives.

Fortunately, this is doable. Because smaller breeds tend to have longer lives than bigger breeds, it is critical to determine your dog’s age according to the appropriate category: small (9.5kgs or less), medium (9.6kgs-22kgs), large (23kgs-40kgs), orgiant (above 40kgs) (over 41kgs).

Despite the fact that the origins of the seven-year myth are unknown, humans have been attempting to devise a reliable method of converting dog years into human years since the 1200s. One of the earliest examples of this is an inscription in Westminster Abbey that dates back to the year 1268 and calculates that one human year is equivalent to nine dog years, which was part of some strange method of calculating the end of the world in the 1200s. Another example is an inscription in the British Museum that dates back to the year 1268 and calculates that one human year is equivalent to nine dog years.

“My assumption is that it was a marketing trick,” said a veterinarian at Kansas State University, according to The Wall Street Journal.

Dog Age Chart: How Old Is Your Dog In Human Years?

Writer and dog-and-cat mom with a lot of content|+ posts A writer and former associate digital content editor at the American Kennel Club, Randa has written for a variety of publications. She is also the mother of one Corgi and two orange kittens. That one year of a dog’s life is equal to seven years of human life is conventional information, right? Well, not exactly. Not to worry if this is the method you’ve been using to determine the age of your dog, you’re not alone. However, the reality is that this strategy is not completely accurate.

Scientists and academics have created a more exact technique of converting the age of a canine into human years in the modern day.

How do I calculate my dog’s age in human years?

If you want to be more exact when calculating your dog’s age in human years, you may use a new formula developed by experts at the University of California San Diego School of Medicine. These researchers investigated the way DNA changes in humans and dogs through time by looking for patterns known as methyl groups in the DNA of humans and Labrador Retrievers. Based on their findings, they determined that you can convert a dog’s age to human years by multiplying the natural logarithm of the dog’s age by 16 and adding 31 to the result.

This calculation is somewhat sophisticated, as you can see from the example above.

This approach may be used to estimate the age of small, medium, and big dogs weighing less than 100 pounds.

  • It takes a dog one year to live the same amount of time as a human year. The second year of a dog’s life is equivalent to around nine years in human life. For every additional year, around four or five human years are gained.

It takes a dog one year to live the same amount of time as it takes a person. It takes a dog around nine human years to reach the age of two. It takes around four or five human years to complete each extra year;

Dog Age Calculator Chart

As you can see in our dog age chart, tiny, medium, and big dogs all age in a similar manner until they reach roughly the age of six, with the exception of the enormous group. Then there’s the fact that bigger canines age considerably more quickly than their smaller and medium-sized counterparts. A little dog, such as a Dachshund, will be six human years younger than a big breed, such as an Airedale Terrier, by the time it reaches the age of seven. What is the reason behind this? As a result, experts are baffled as to why smaller canines age more slowly and live longer lives than their larger counterparts.

In a similar vein, bigger dogs mature considerably more quickly from puppyhood to maturity, increasing the likelihood of aberrant cell proliferation, cancer, and other disorders.

It’s still tough to put a general formula on the way dogs age, even with the more accurate updated technique we’ve presented.

What are common signs of aging in dogs?

As a result, it might be beneficial to seek for physical and behavioral indicators to identify your dog’s age when determining his or her age. Teeth, for example, might be a very good predictor of your dog’s age when it comes to identification. According to PetMD, all of your dog’s permanent teeth will be in by seven months; by one to two years, they will be duller and perhaps yellowed; and by five to ten years, they will show indications of wear and illness, according to the website. The following are some additional markers of your dog’s age, particularly as they approach the senior stage:

  • Graying hair, poor vision, hazy eyes, difficulty hearing, stiff muscles and joints, arthritis
  • These are all symptoms of aging. Reduced amount of activity Behavioural changes, such as increased worry, bewilderment, home accidents, anger, and so on

If you’re still unclear, you may always consult with your veterinarian for an exact assessment of your dog’s age. Your veterinarian will analyze a variety of variables, such as teeth, body form, hair or fur, and eyes, among others, in order to provide the most accurate estimate of their age.

Why is understanding my dog’s age important?

A dog age chart, which can be used to estimate your dog’s age in human years, is a fun and enlightening method to discover more about your dog! It is also crucial for a variety of additional reasons. Understanding the age of your dog and the progression of their aging helps you to properly care for them – and help them live the best life possible. To be on the safe side, larger dogs should be checked for indications of aging around the age of five or six, whilst smaller dogs may not show any signs until the age of seven or eight, depending on the breed.

The following factors will all assist to extend the life expectancy of your dog: a balanced diet and weight, consistent mental stimulation and physical activity, and frequent check-ups with the veterinarian.

Indeed, your dog deserves the finest possible treatment no matter how old they are – which is why Pumpkin protects pets of all ages with our pet insurance.

The bottom line…

The fact of the matter is that, despite the fact that the widespread “one canine year equals seven human years” technique has been around for years, it is not particularly accurate. Fortunately, because to recent research, we now have a more reliable method of determining the age of our canines. You may always refer to our dog age to human years chart (or even print it out!) to quickly and simply figure how old your pet is, even if the arithmetic is a little more complicated than a basic 1:7 ratio.

How old is my dog in human years?

Dogs age at a faster rate than humans, owing to their shorter lifetime. While a 14-year-old human youngster is on the verge of entering adolescence, a 14-year-old canine has already reached the age of grandparenthood. It turns out that the commonly held belief that one canine year equals seven human years is incorrect. The reality, however, is a little more convoluted than that. Canines do not all age at the same pace; huge, heavier dogs age more quickly than smaller dogs and do not have the same lifetime as smaller dogs.

Dog years to human years chart

While some huge dogs, such as the Great Dane, enter their senior years around the age of 6 or 7, small-sized canines may still be in their adolescence at the same time! Large dogs have cells that proliferate more quickly than small dogs, which may make them more susceptible to malignant tumors.

How can I make my dog live longer?

How Old Is Old Comparing Dog Age To Human Age

Watching your puppy pup jump over the yard is a pleasant pastime. You notice your elderly dog slowly making his way to the food bowl. You go for a vigorous run, your young puppy following close behind you on the trail. You take your time walking to the mailbox, and your elderly dog continues to lag behind. The impact a few years can make in the life of your dog. Why does your dog appear to be getting older while you don’t? Perhaps this is due to the fact that your dog and your definition of “aged” are significantly different.

Doing the Math

You stand back and watch your little dog jump over the yard with his tail between his legs. When your elderly dog approaches the food dish, you see that he is lumbering slowly. You go on a vigorous run, your young puppy following close behind you. Even though you are taking your time, your elderly dog continues to trail you. The impact a few years can make in your dog’s appearance. So, why does your dog appear to be getting older? Is it possible that you and your dog have dramatically different ideas of what constitutes “old age”?

Why simple math won’t work

“It is well established that comparing canine age to human age presents difficulties.” It is commonly established that comparing the age of a dog and a human is difficult. Due to the fact that a dog matures and develops more swiftly during its first two years of life, the classic 7 dog years = 1 human year hypothesis is wrong. In addition, the ratio changes depending on the breed and size of the dog. Even the more widely recognized calculation, which uses the 10.5 factor for the first two years of a dog’s life and the 4 year factor thereafter, has flaws since it does not take into consideration the dog’s size and breed.

Small, medium, and big are the classifications used by this system, which more particularly considers the predicted mature weight of the canines.

So, what’s the answer to the math problem?

Who knows what will happen? The most straightforward equation (7:1) is also the least accurate. Formulas that take into account the quicker development that happens during the first two years of life provide a more realistic comparison of the two ages. Even with this notion, however, there is some variety. Some mathematicians believe that a one-year-old dog should be equated to a human who is 15 to 20 years older than the dog. As development reaches a plateau, the second year should be equivalent to 3 to 8 years of human life expectancy.

  1. However, this is still a wide range.
  2. In a nutshell, there is no definite solution to the mathematical issue.
  3. There are too many breeds.
  4. However, one thing that remains constant is the fact that dogs age more quickly than their owners do.

Consistently, the energy level of a 4-year-old dog is comparable to that of a young adult. The fact that a 9-year-old dog walks with the stiff stride of an elderly adult is a consistent observation.

Emotional Ageing

To make matters even more complicated, emotional development does not often coincide with physical maturity. Emotional maturity is a process that takes place over a long length of time. For example, a human who is 21 years old is considered an adult, yet he or she may not acquire emotional maturity until they are 40 or so years old. The same is true for canines. Despite the fact that a nine-month-old puppy may be socially and sexually active, true maturity does not occur until the third or fourth year of life.

So, what is old?

When is seniority granted to a person? When it comes to humans, some people regard those above the age of 55 to be senior citizens. Others don’t impose that status until after they’ve reached the age of 65. Canine seniority is also subject to change. The age at which little dogs are considered senior citizens of the canine world is 11 years when they accomplish this milestone. When they reach the age of ten, their medium-sized pals become seniors. Their older, larger-sized companions are seniors, having reached the age of eight.

As a result, a Great Dane reaches the age of retirement far sooner than a Pomeranian.

Signs of Ageing

Dogs, like people, suffer from the consequences of aging, which include:

  • Gaining in weight and losing energy are all side effects of glaucoma treatment. arthritis and other joint disorders, muscular atrophy, and tooth loss are all possibilities. Organ damage (heart, liver, and kidneys)
  • Loss of organ function. Skin elasticity is being eroded. Hair loss is a common occurrence. Impaired immunity
  • Diminished mental sharpness

With aging comes a great deal of sadness, but there is also a great deal of satisfaction in reflecting on a life (human or canine) that was well-lived. So forget about the mathematics for a while. The happiness you have with your pet should never go away.

Dog Years To Human Years Calculator

The contemporary dog has developed into the most varied animal on the planet as a result of selective breeding techniques used throughout history. It is possible for dogs to weigh anything between 4 and 200 pounds, and their body shapes and coats exhibit a wide range of variations. The duration of a dog’s life is mostly determined by its size, which is the polar opposite of how it is generally determined in mammals. Large animals, such as horses, live for far longer periods of time than small animals, such as mice.

  • The Great Dane, despite his height and stature, will normally survive just 6 or 7 years.
  • Genetics, of course, have a significant part in one’s ability to live a long life.
  • A pedigreed dog tends to have a shorter life than a mixed breed of the same size, which has a statistically higher chance of surviving an extra year if cared for properly.
  • Breeds with the longest lifespans include:
  • Miniature Dachshunds, Miniature Poodles, Bearded Collie, Border Collie, and more breeds are available.

Breeds with the shortest lifespans include: There are, of course, certain exceptions to this rule.

In spite of living in the harsh climate of Mongolia, the Mongolian Bankhar, a colossal protector of cattle, is famed for living into its teens and even into its early twenties.


It might be difficult to determine your dog’s age according to human standards, especially when there are so many variables to consider, including as breed, size, and hereditary predispositions to hip dysplasia and other abnormalities. Online dog age calculators are available for free, and they can assist you in determining the approximate human age of your dog. Enter the facts about your dog and press a button, and your response will appear on the screen. Just keep in mind not to take anything too seriously at first.

The fact that the dog age calculator illustrates how long dogs have played a key role in the history of humans is maybe the most essential feature of the tool.

Dog Years – How Old is My Dog in Human Years?

We all want that our canine companions could live as long as we do, if not even longer if it were possible. However, the fact is that their life expectancy is far shorter than ours, and many dogs are actually fully grown adults by the time they reach the age of two. In this post, we’ll teach you the quickest and most accurate method of converting dog years to human years, so you can determine precisely how old your dog is.

Why the most famous rule to calculate dog years to human years can sometimes be wrong?

In order to figure out how old your dog is, you’ve undoubtedly followed the following simple arithmetic rule: multiply their dog age by seven to find their age equivalent in human years. The calculation was most likely based on the fact that, although the majority of humans live to be 70 years old, dogs live on average for just 10 years. This rule, on the other hand, does not always produce trustworthy outcomes. When it comes to life expectancy, the size and breed of the dog are crucial considerations, with smaller types often having longer lives than bigger breeds.

Generally speaking, large and gigantic breeds reach old age by the time they are five years old, but medium-sized dogs do not reach old age until they are seven years old.

How to calculate dog years to human?

According to the Kennel Club of the United Kingdom, the following are the general standards for determining the age of a dog:

  • The first two years of a tiny dog’s life are roughly equivalent to 12.5 human years, whereas the first 10 years of a medium dog’s life are equal to nine years of life for a large dog. Afterwards, for each extra year of the dog’s life, the human age is calculated by multiplying it by a factor of between 4.3 and 13.4 years depending on the breed.

You’ve probably heard for years that the best way to figure out a dog’s age in “dog years” is to simply add seven years to each year that the dog has been alive. That ought to provide you with the human equivalent of your dog’s age, shouldn’t it? Wrong! The chart below can help you precisely calculate the age of your dog in canine years, which are different from human years.

Farmer’s Almanac is the source of this information. The values presented above are based on “averages,” and they are typically applicable to the majority of dogs. However, there is a newdog age calculator that also takes the breed of the canine into mind! It is because size and heredity are important factors in deciding how quickly and how long a dog will survive. The following chart combines your dog’s chronological age with his or her height and weight to establish the physiological age of your dog: The physiological age of a dog takes into consideration all of the processes that are in place to keep the body alive and operating properly.

Dog Age vs. Human Age: Mental/Behavioral Age

It becomes more about a dog’s “maturity” rather than about his mental capacity or real intellect at this point. It has been said (sadly) that a dog’s IQ level is on par with that of a 2-year-old person when only looking at intelligence. That, of course, is speaking in broad terms — and it applies to dogs of all ages and breeds. I mean, my dog appears to be far more intelligent than a 2-year-old! And I’m sure yours does as well. However, the reality is that all dogs have the capacity to learn, grow, and flourish at a higher (or lower) rate than other dogs their own age.

  1. A 10-year-old dog is believed to be emotionally equal (or “acts like”) a 70-year-old person, but a 12-year-old dog is thought to be extremely similar to (or “acts like”) an 84-year-old human.
  2. When it comes to emotional development, it is not the same as physical maturity.
  3. For example, a human who is 21 years old is considered an adult, yet he or she may not acquire emotional maturity until they are 40 or so years old.
  4. Despite the fact that a 9-month-old puppy may be socially and sexually active, true maturity does not occur until the age of three or four.
  5. VCA Hospitals is an abbreviation for the Virginia Commonwealth University Hospitals.

Calculate dog age in human years (equivalence)

A lot of people believe that in order to get the “human” age of a dog, you just increase its age by seven, which is incorrect. That is just incorrect! Because the age of a dog does not follow a linear curve when compared to the age of a human, there is no mathematical formula (at least not a simple one) that can be used to calculate its age. The stages of “childhood” and “adolescence” occur significantly more quickly in animals than in humans. It is true that dogs develop five times quicker than humans during their first year of life!

Real dog age 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18
Small dog age 20 28 32 36 40 44 48 52 56 60 64 68 72 76 80 84 88 94
Average dog 18 27 33 39 45 51 57 63 69 75 81 87 93 100
Big dog age 16 22 31 40 49 58 67 76 85 96 105

Note: A little dog is defined as a dog weighing less than 15 kg, an average dog is defined as a dog weighing between 15 and 45 kg, and a large dog is defined as a dog weighing more than 45 kg. Finally, the larger a dog is (based on its breed), the slower its growth will be in its youth, but it will become old more rapidly and have a shorter life. An average dog can live between 10 and 15 years, depending on his or her breed and body size (and his breed).

And you, how old is your dog?

If humans had Jeanne Calment, the oldest dog on the planet would have been a dog named Bella, who would have lived to reach a hundred years old. When she died, she was 29 years old in Clay Cross, United Kingdom, which would have made her a person who had lived approximately 202 years! Although the unfortunate puppy has been officially documented in the Guinness Book of Records, his master was unable to prove his age because he did not have a birth certificate.

Here’s a better way to convert dog years to human years, scientists say

Buckaroo, our Scotch collie, is 14 years old and still going strong. As a result of the long-debunked but still widespread belief that one canine year is equal to seven human years, he is approaching centenarian status. In this case, the “formula” may be based on the average life spans of dogs and people, which are 10 and 70 years, respectively. Researchers claim to have developed a new method (see calculator below) for converting canine years to human years, one that is based on sound scientific principles.

  • According to scientists, one of these modifications, the insertion of methyl groups to certain DNA sequences, tracks human biological age—that is, the toll that disease, a bad lifestyle, and heredity have on our bodies as we get older.
  • Other animals, such as humans, also experience DNA methylation as they get older.
  • Geneticist Trey Ideker of the University of California, San Diego, and colleagues started with dogs to see how their clocks differed from the clocks used by humans.
  • All dogs, regardless of breed, develop in a similar manner, reaching puberty about 10 months of age and dying before the age of 20.
  • They studied the DNA methylation patterns in the genomes of 104 dogs ranging in age from 4 weeks to 16 years, and found that they were all different.
  • Most crucially, scientists discovered that particular sets of genes involved in development are methylated in a similar manner in both animals as they get older.

According to Matt Kaeberlein, a biogerontologist at the University of Washington in Seattle who was not involved in the research, “We already knew that dogs suffer from the same diseases and functional declines associated with aging as humans do, and this work provides evidence that similar molecular changes are also occurring during aging.” “It’s a fantastic representation of the preserved aspects of the epigenetic age clocks that are shared by dogs and humans,” says the researcher.

Dog methylation alterations were also employed by the study team to match the pace of changes to the human epigenetic clock, however the resultant dog age conversion is a little more complicated than “multiply by seven.” When a dog is more than one year old, the new formula determines that a canine’s human age is approximately equivalent to 16 ln(dog age) + 31 years old.

According to the methylation data, the life phases of dogs and humans appear to be comparable.

A further benefit of the method is that it accurately correlates the average life span of Labrador retrievers (12 years) with the worldwide life expectancy of humans (70 years).

In both animals, “they’ve demonstrated that DNA methylation increases gradually with age,” says Steve Austad, an evolutionary biologist and aging expert at the University of Alabama in Birmingham.

That is one of Kaeberlein’s goals, and his group’s newDog Aging Project (which is available to all breeds) will incorporate epigenetic profiles of its canine patients as part of its research.

So, how does our Buckaroo fare in this situation?

He’s just 73 years old in human years—and a remarkably healthy 73 at that. Updated at 10:52 a.m. on November 16: This item has been modified to include a phrase that explains why young dogs appear to be middle-aged in human years when using the age calculator.
