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 a 2 year old dog still a puppy?
In general, puppies become adult dogs between one and two years of age. But it’s not like they wake up the morning of their first birthday and are suddenly grown-up dogs! In fact, puppy maturation is a process, and it varies from dog to dog depending on size, breed, socialization, and more.
Is a 2 year old dog full grown?
Physical Maturity: Physically speaking, dogs are fully grown by the time they ‘re 1 year old, although large breeds may keep growing until they’re 2 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.
Is 8 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 5 old for a dog?
At age 5 and 6, your dog should still have plenty of energy and, with proper care, many years left to enjoy with you. There is huge individual and breed variation in life expectancy, but your 5-year-old dog is generally considered to be approaching middle age.
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 should I expect from a 2 year old dog?
Most dogs are physically mature when they hit the age of 2. By the time most dogs are 2 years old, they have all their permanent adult teeth. Those sharp little puppy teeth are gone! That fuzzy puppy coat is gone, too, and the hair you see at age 2 is the hair your dog will be wearing the rest of his life.
Is a 2 year old German Shepherd a puppy?
A two-year old GSD is still pretty much a puppy.
Is 3 old for a dog?
By age 3, your dog is in her prime and ready to enjoy her best years. She is fully integrated into your home and a real member of the family. If you have done your work — putting in the time and effort to train and exercise your dog — this phase is your reward. She is now officially your best friend.

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?
Researchers at the University of California, San Diego published a paper in 2019 that proposed a novel approach for determining the age of a dog that was based on variations in both human and canine DNA throughout time. The addition of methyl groups to DNA molecules occurs in both species throughout the course of life, affecting the function of DNA but leaving the DNA itself mostly unchanged. Consequently, scientists have employed DNA methylation to investigate human aging by creating a “epigenetic clock” to track the progression of the disease.
It was possible to construct 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) based on the findings of the experiment.
It is possible that your dog’s “human age” based on this formula will be slightly different from the results of the research because it only included a particular breed of dog.
It doesn’t matter how you look at it, the new science-backed method that has been proposed is unquestionably more beneficial for folks who want to compute their dog’s “human age” than the long-debunked “multiply by 7” approach.
Dog Age Chart: Dog Years to Human Years
Researchers at the University of California, San Diego published a paper in 2019 that proposed a novel approach for determining the age of a dog that is based on variations in both human and dog DNA throughout time. Throughout the lifespan of both species, methyl groups are added to DNA molecules, affecting the function of DNA without modifying the DNA itself. Consequently, scientists have employed DNA methylation to examine the aging process in humans by employing a “epigenetic clock.” 104 Labrador Retrievers were subjected to targeted DNA sequencing over a 16-year period in an attempt to compare the epigenetic clocks of dogs and humans.

Different breeds age differently, and hence the UCSD model may not have enough variables to produce conclusive findings.
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.
Visit your veterinarian on a regular basis for checkups; modifications may be made to make your dogs’ lives more pleasant, longer, and more healthy.
- 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.

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. 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.
- The age of your puppy or dog may be unknown if you have adopted them from a shelter or have no knowledge of their past. It’s possible to predict someone’s age even if they don’t know their birth date. Your best guess as to their age should be their teeth. These recommendations will differ from dog to dog, and they will also vary depending on the type of dental treatment (if any) they received before to coming to you with your dog.
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.

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 is easier (and more accurate) than other methods of estimating the age of dogs.
- 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.
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.
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. Pet dogs of all sizes, including little and toy types, attain seniority around the age of 10.
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.

What is the oldest dog in Britain?
In November 2014, Britain’s oldest dog, a Jack Russell named Meg, reached the grand old age of 25 – which is about 113 years in dog years!
Dog Years To Human Years
Because a dog’s lifespan is one-seventh that of a person’s, dog years are multiplied by seven to obtain a human age. The conversion of dog years to human years is dependent on a number of things. All breeds of dogs grow and mature in their own ways, which is why dogs up to 50 lbs. can live longer than pups up to 100 lbs. in the same environment. According to expert opinion, a dog’s level of maturity during its first two years is comparable to that of a 14-year-old person, but that’s about where the similarities end.
- Breed, size, weight, activity level, diet, lifestyle, health, and life span are all factors to consider.
Comparing age: Dog years vs Human years
While most pet parents have been calculating their pup’s dog to human years for a long time, the process has no basis in fact, and the conversion of human years to dog years is primarily used for amusement purposes instead of scientific research. Take a look at the dog years converter and estimate how old a toy, small, medium, big, and gigantic dog breed is in human years based on their age in dog years.

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. Overall, the average lifespan of a pedigreed dog is 12 years. 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.
Many of us consider our dogs to be members of our families, and we want to provide them with the best possible life.
All we can do is calculate the averages and hope for the best, and that is all we can do.
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.

Calculating Your Dog’s Age
Your dog’s equivalent age in human years may be calculated using the “multiply by 7” rule, which you are most likely familiar with. Despite the fact that this is a simple method of generating a number, research has revealed that it is not particularly accurate. The concept of “multiplying by seven” was probably inspired by the average worldwide lifespans of dogs and humans, which are 10 and 70 years, respectively. The difficulty is that dogs mature considerably more rapidly than people do during their first few years of life, and this is especially true for puppies.
Research conducted by scientists from the University of California at San Diego and the National Institutes of Health, as well as researchers from the University of Pittsburgh School of Medicine and the University of California at Davis School of Veterinary Medicine, looked into the DNA patterns in the DNA of a group of 104 Labrador Retrievers ranging in age from 4 weeks to 16 years.
- It is a biological process in which methyl (CH3) groups are added to DNA molecules, which is known as methylation.
- The addition of methyl groups to DNA in both humans and dogs as they age allows the use of mathematical models known as “molecular clocks” to determine the age of the animal in question.
- The first 8 weeks of a dog’s existence corresponded closely to the first 9 months of a human’s life, resulting in life expectancies of 12 and 70 years, respectively, for the two species.
- For the natural log, the acronym “ln” stands for “natural log.” The following is a breakdown of the comparable life stages:
|Dogs’ Age||Humans’ Age|
|First 8 weeks||First 9 months|
|2 – 6 months||1 – 12 years|
|6 months – 2 years||12 – 25 years|
|2 – 7 years||25 – 50 years|
|7 – 12 years||70 years|
In order to establish your dog’s equivalent age in human years, you are surely familiar with the “multiply by 7” rule. Despite the fact that this is a simple method of generating a number, study has revealed that it is not particularly precise. Considering the typical worldwide lifespans of dogs and humans, which are 10 and 70 years, respectively, the “multiply by 7” concept is most likely inspired from these figures. Unfortunately, dogs age far more rapidly than people do during their first several years of life, which creates a difficulty for owners.
In this study, scientists from the University of California at San Diego, the National Institutes of Health, the University of Pittsburgh School of Medicine, and the University of California at Davis School of Veterinary Medicine examined DNA methylation patterns in a group of 104 Labrador Retrievers ranging in age from four weeks to sixteen years old.
When methyl (CH3) groups are introduced into the DNA structure, this is known as methylation.
Methylene groups are added to DNA as people and canines get older, allowing mathematical models known as “molecular clocks” to be used to determine their ages.
When comparing the first 8 weeks of a dog’s life to the first 9 months of a human’s life, researchers discovered that they were almost identical, with life expectancies of 12 and 70 years in both cases.
As a result of gathering this information, researchers devised the following equation to determine the age of a dog in human years: Age of a human being equals 16 ln(dog age) plus 31. For the natural log, the abbreviation “ln” is used. The following is a breakdown of the equivalent stages of life:
- In comparison to humans, one year of age for a medium-sized dog is comparable to 15 years of age. Two years of age for a dog is equivalent to nine years of age for a human. As a result, each human year is comparable to 5 years in the life of a dog.
Small dogs are considered “senior” by the American Veterinary Medical Association (AVMA) at the age of seven, but bigger breeds are deemed “senior” at the age of five or six. Despite the fact that these figures are preliminary approximations, they can assist you and your veterinarian in providing the finest care possible for your pets as they get older. Dogs live alongside us, share our habitats, and suffer from many of the same age-related illnesses that we do as humans. In order to evaluate age-related health concerns like as arthritis, weight control, and impairments in hearing or vision, it is necessary to first determine your dog’s age and biological life stage.
For more information:
Larger breeds are regarded “senior” around 5 or 6 years of age, whereas tiny dogs are deemed “senior” at 7 years of age, according to the American Veterinary Medical Association (AVMA). This information is approximate, but it can assist you and your veterinarian in providing the best care possible for your pets as they get older. Dogs coexist with us, share our habitats, and suffer from many of the same age-related illnesses as we do as we grow older. In order to examine age-related health concerns like as arthritis, weight control, and hearing or vision deterioration, it is necessary to first determine your dog’s age and biological life stage.
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|
|Big dog age||16||22||31||40||49||58||67||76||85||96||105|
There are a number of individuals who believe that in order to determine the “human” age of a dog, you just increase the dog’s age by 7. That is just incorrect! The age of a dog does not follow a linear curve when compared to the age of a person, hence in practice, there is no mathematical formula (at least, there isn’t one that is easy). “Childhood” and “adolescence” occur far more quickly in animals than they do in humans. It is true that dogs develop five times quicker than humans during their first year of life.

As a result, veterinarians have developed a correlation table (age chart) based on observations of canine ages in order to evaluate if there is a similarity in human ages:
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.
