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.
- If your dog weighs 20 pounds or less, then one human year equals 15 dog years. However, if your dog 100 pounds or more, then one human year equals 12 dog years! Also read: Can Dogs Have Asthma? Signs And Symptoms

Is 1 year really 7 years for a dog?
Dogs are much older than we think, and researchers devised a more accurate formula to calculate a dog’s age based on the chemical changes in the DNA as organisms grow old. According to the well-known “rule of paw,” one dog year is the equivalent of 7 years.
How old is a 2 year old dog in 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.
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.
Is 7 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 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 17 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.
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.
How old is a 4 year old dog in human years?
A 4-year-old dog is similar to a 52-year-old human. Then by seven years old, dog aging slows.”

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 area of research, as dog owners want to not only prolong the amount of time they spend with their dogs, but also to increase 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 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.
A large puppy may appear to age more slowly at first, but by the age of five, he or she will be approaching middle age. 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. Even if you don’t know their exact birth date, you may make an educated guess as to their age. Their teeth should be able to give you a general sense of how old they are. 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 may also make an educated prediction 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
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
Statistics from pet-insurance companies, breed-club surveys, and veterinary clinics have all contributed to our understanding of how dogs age and how to keep them healthy. The prevalent misconception is that dogs age at a pace of 7 human years for every year in dog years. This is not true. The American Veterinary Medical Association (AVMA) says the following:
- 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.
In other words, during a dog’s rapid growth to maturity, the number of human years accumulates more swiftly on the dog’s life.

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.
- The first year of a dog’s life is equivalent to approximately 15 human years
- The second year of a dog’s life is equivalent to approximately nine human years
- And so on and so forth. For every additional year, around four or five human years are gained.
So, what makes this technique more accurate than the “one dog year equals seven human years” method, you might wonder. Because it takes into consideration the fact that not all dog breeds age in the same manner. A seven-year-old Great Dane may be regarded a “senior” dog, but the same is not always true for a seven-year-old Chihuahua. In general, smaller canines enjoy longer lives than larger dogs. As a result, it is beneficial to split down a dog age chart in terms of size, as you will see in the next section.
To find out how old your dog is in human years, use the table below to convert their dog age to human age depending on their size group:
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. This is due to the fact that this progression will vary depending not just on your dog’s size, but also on their breed and individual genetics as well.
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 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 your dog in human years? New method better than ‘multiply by 7’
In human years, how old is your wagging-tailed bundle of happiness? To put it another way, according to the well-known “law of paw,” one dog year is equal to seven years. Scientists now claim that this is incorrect in a paper published on July 2 in the journal Cell Systems. We don’t realize that dogs are much older than we believe, and scientists have developed a more precise formula to determine a dog’s age based on the chemical changes that occur in the DNA of creatures as they age. In addition to sharing a same habitat with their owners and receiving almost the same level of health care as humans, dogs provide a unique chance for scientists to better understand the process of aging across species.
- However, the way they age on a molecular level is more difficult – they mature swiftly at initially and then slowly as they go further along in their lives.
- You know right away that if you do the arithmetic, you don’t simply multiply seven times seven, you multiply seven times seven “Trey Ideker (@TreyIdeker) of the University of California, San Diego is a senior author on the study and can be reached through Twitter.
- The DNA of humans and dogs, which contains the genetic code that determines who we are, does not change much during life, but chemical marks on the DNA, known as methylation marks, do.
- I like to think of it in terms of when you look at someone’s face and guess their age based on wrinkles, gray hair, and other traits,” he adds.
- ” They worked with two canine specialists, Danika Bannasch of the University of California, Davis, and Elaine Ostrander of the National Institutes of Health, to study 104 Labrador retrievers ranging in age from a few weeks to 16 years.
- They compared the changes in the methylation pattern in mice to changes in human methylation patterns.
- The new function estimates that an 8-week-old dog is around the same age as a 9-month-old baby, owing to the fact that both are in the newborn period, during which pups and infants are developing teeth.
- “I enjoy taking my dogs for walks, and as a result, I’m a little more sympathetic to the 6-year-old now,” says Ideker, who learned that his dog, according to the new estimate, is approaching the age of sixty.
- According to Ideker, by the time a person reaches adulthood and stops developing, “you’ve basically turned off these genes, but they’re still there burning.” It’s still evolving when you look at the methylation marks on those developmental genes,” says the researcher.
- Moreover, according to Ideker, further research into different dog breeds with varying lifespans may give more insight into the new clock.

Your 1-year-old dog isn’t 7 human years old, contrary to the traditional math. It’s more like 30 years old, new research shows.
- According to a widely accepted rule of thumb among dog owners, one year in the life of a dog is comparable to seven human years. However, according to recent study, young pups age considerably more quickly than young people, indicating that the traditional one-to-seven-year ratio is incorrect. According to one expert, a one-year-old canine is more “like a 30-year-old person.” Dogs, on the other hand, mature more slowly as they become older. Consequently, experts discovered that a 12-year-old labrador would be the equal of 70 human years in human years. More articles may be found on the Business Insider homepage.
Dogs live an average of 12 years throughout their lifetime. Humans, on the other hand, have a life expectancy that is at least five times greater. This disparity is a contributing factor to the widely accepted rule of thumb that one “dog year” is equal to seven “human years.” A new study published in the journal Cell, however, finds that the one-to-seven ratio is incorrect. This is due to recent genetic research indicating that pups and younger canines mature at a quicker rate than their older counterparts.
According to the study, a 6-year-old dog would be the human equivalent of around 60 years old.
“I’m a little more sympathetic to the 6-year-old now,” he added.
An 8-week-old puppy is the equivalent of a 9-month-old baby

Photograph courtesy of Angela Auclair/Getty Images It was Ideker’s team’s investigation of chemical markers in the DNA of 104 labrador puppies varying in age from only a few weeks old to 16 years old that enabled them to develop an improved formula for comparing human and dog ages. Despite the fact that an animal’s DNA does not alter throughout the course of its life, these chemical identifiers, known as methyl groups, do.
- After measuring the pace at which these methyl groups accumulated in different sections of their genomes over time, the researchers compared the accumulation rate to the identical methyl group alterations observed in humans over the same period of time in humans.
- As a result, an 8-week-old dog is the same age as a 9-month-old infant.
- In the end, one canine year does not equal seven human years in any way.
- In the researchers’ calculation, a dog’s human age is calculated as follows: 16 ln * yourdog’s age + 31.
- Photograph courtesy of Shutterstock The gist of it is that for every year that a dog grows older, the proportional gain in “human years” grows smaller and smaller.
- A 12-year-old lab, on the other hand, is 70 years old in human years.
It’s challenging to equate human and dog aging
According to the findings of the current study, methyl groups accumulated on several of the same genes in both dogs and humans as both animals aged. According to the study’s authors, this makes sense because dogs live in the same household as their owners and receive virtually the same level of medical care as their owners. Nonetheless, age matching does not hold true for the hormones and behaviors of the two species. Photograph of a little girl with her dog. Photograph courtesy of Brittany Schauer Photography/Getty Images However, Asher explained to The Guardian that while a 30-year-old person could have cells that are equivalent to those of a 1-year-old dog, many canines will not be completely developed at this time and would still have disturbed hormones and behavior associated with adolescence.
It’s difficult to discover a clear match between a dog’s age and that of a human because “the growth of dogs is not simply a condensed version of the development of humans,” Asher continued.
1 Human Year Equals Seven Dog Years? Think Again.
Canine owners are all too aware with the stock-standard calculation, which states that “one dog year equals seven human years.” The difficulty is that this equation was never established on the basis of solid scientific evidence. As a result, it is most likely based on a comparison between the average longevity of dogs (about 10 years) and the average lifespan of humans (approximately 70 years), and therefore fails to account for changes in the maturation arc between the two species. Following an investigation conducted by Trey Ideker and colleagues at the University of California, San Diego, new in-depth research has revealed that the “one dog year equals seven human years” equation is incorrect, concluding that dog and human aging are significantly different, as well as that the relationship between human and dog age is nonlinear.
A one-year-old dog is actually equivalent to a 31-year-old human, rather than a seven-year-old human, while a two-year-old dog is equivalent to a 42-year-old human and a three-year-old dog is equivalent to a 48-year-old human, with the researchers observing a smaller and smaller increase in the human-age equivalency of the dogs as the dogs age, according to the findings.
They discovered that the DNA profiles of dogs and humans may be matched at specific ages by comparing commonalities between them.
They used the results of these matches to develop a new formula for converting between canine years and human years.
It turns out that your three-year-old puppy, who you believed was comparable to a 20-year-old, may actually be approaching the age of 50!
How old is your dog in human years? Forget the 7-year rule, study says
Whenever we think about how old we think our dogs are in human years, the majority of us employ a computation based on the fact that dogs live seven years for every one that humans live in human years. As a result, from a developmental standpoint, a 1-year-old dog is about equivalent to a 7-year-old person. A 2-year-old dog is the equivalent of a young adolescent, and so on and so on. According to a report in USA Today, a new study by academics at the University of California San Diego School of Medicine, in collaboration with other experts from throughout the country, is calling into question the math in question.
A total of 104 Labrador retrievers between the ages of four and sixteen years old participated in the study.
According to the study’s senior co-author Trey Ideker, professor at the University of California, San Diego School of Medicine and Moores Cancer Center, “This makes sense when you think about it — after all, a nine-month-old dog can have puppies, so we already knew that the 1:7 ratio wasn’t an accurate measure of age.” A new study published on July 2 in Cell Systems is the first to be transferable between species, and it provides vets with a tool “for assessing anti-aging therapies,” according to the researchers.
According to Ideker, “There are a plethora of anti-aging products on the market today – each with radically differing degrees of scientific backing.” ‘However, how can you tell whether or not a product can actually lengthen your life without having to wait 40 years or more?’ Why not instead test your age-associated methylation patterns before, during, and after the intervention in order to discover if it has any effect?
- Methylation patterns are the formula that is used to compute a dog’s age in terms of human years, and they are described below.
- According to the findings of the study, while dogs age swiftly in their early years, once they reach a specific age, the aging process slows down.
- A 4-year-old dog is comparable to a 52-year-old person in terms of age.
- You may use the Google calculator to estimate the approximate age of your dog.
- Afterwards, select the “ln” option to obtain the natural logarithm (also known as the ln) function.
When you get that figure, multiply it by 31 to obtain the equivalent of the dog’s age in years of human life. As a result, a 7-year-old dog would be around 62.1 years old in human years. Cox Media Group is a media company based in the United States.
How Old Is Your Dog In Human Years? You Don’t Multiply By 7…
According to the American Kennel Club, the first year of a medium-sized dog’s life is similar to 15 years of a human’s life in terms of time. For a person, his or her second year of life is equivalent to nine years. After then, each following human year corresponds to around five years for the canine. At the age of seven years, little dogs are typically considered senior pets by the general public. Larger dogs, on the other hand, tend to live shorter lives and are sometimes referred to as senior pets when they are just five or six years old.

However, because it incorporated breed-specific data, further investigation is required.
According to PetMD, the life expectancy of a dog varies significantly depending on its size and breed. When compared to bulldogs, who typically live six years on average, golden retrievers can live up to twelve years on average. According to a 2013 research conducted by Banfield Pet Hospital, dogs weighing less than 20 pounds have an average lifespan of 11 years, but dogs weighing more than 90 pounds had an average lifespan of just eight years. However, there are certain outliers, and some pets have shorter or longer lifespans than the typical animal.
When determining the average lifetime of a dog, it is necessary to take their weight into mind.
Two canines who were born in the same year had a 21-year age gap between them.
More Research Is Needed
Researchers are baffled as to why tiny canines live longer lives than their larger counterparts. In the opinion of Cornelia Kraus, an evolutionary biologist at the University of Göttingen in Germany, there are a number of possible explanations. Large dogs may age more quickly, or they may just begin to age sooner. Alternatively, they may just have a greater mortality risk. In addition, as compared to large dogs, little dogs have lower quantities of the growth hormone IGF-1 in their blood. It has been shown that high levels of this hormone are associated with an increased risk of dying from age-related problems such as cancer and heart disease.
