How to Convert Your Dog’s Age Into Human Years

Have you ever found yourself looking at your four-legged friend and asking him, “How old are you in human years?” Well, if this is a common practice for you, you’re not the only one doing it. Tens of millions of dog owners ask themselves this question daily  , and, needless to say, the answer isn’t as boring as that
“dog years = 7 human years” myth many people believe.

Why Do We Need To Know Our Dog’s Age in Human Years

In some sense, the human desire to comprehend everything from our own perspective makes us do this. Once we realize that our 8-year-old golden retriever is like an energetic 61-year-old grandma who enjoys going for walks and chasing balls, we immediately figure out why she sometimes takes too long getting out of bed.

Dog age calculators are not just entertaining to use, They help us change the way we view our dog’s nutrition, physical activity, health checks, and even emotional needs.

The “Multiply by 7” Myth And Why It’s Wrong

Let me start with stating that the long-established principle of multiplying a dog’s age by 7 to get their age in human years  is a massive oversimplification. While there is no doubt that it has worked its way from generation to generation, it has been disproved by modern science.

Here are the reasons why:

• A dog’s life is not marked by equal aging. At just one year old, a dog is much more mature biologically speaking compared to a human at only 1/7 of his or her lifespan. Moreover, at about a year old, a dog is ready to have babies, which is the stage that corresponds to a teenager at the age of 15.
• The dog’s breed and its size. While small-sized dogs develop relatively fast in the first months of life and slow down afterwards living longer, giant breeds mature quickly becoming seniors already at five-six years of age.
• The curve of aging is nonlinear rapid aging is characteristic of the first years of a dog’s life and then becomes slower.

How to Calculate Dog Age the Right Way

The Science Behind the Most Up-to-date Dog Aging Calculator

In 2020, scientists from the University of California San Diego conducted an interesting study published in the scientific journal Cell Systems. In it, using the phenomenon of DNA methylation  changes in DNA that occur with age, they compared dog aging with human aging. As a result of their research, a logarithmic equation for translating dog years into human years appeared.

Human Age = 16 × (Dog’s Age) + 31

This  formula showed that not everything is quite as simple as we think. One-year-old dogs turn out to be about 31 years old in human years. Eight-year-old dogs correspond to a 64-year-old person. This tracks far better with what vets observe clinically  things like joint health, cognitive function, and organ aging.

That said, the UC San Diego study was primarily based on Labrador Retrievers. The formula is a great general guide, but it doesn’t fully account for breed-specific aging differences.

The Size-Based Dog Age Calculator

As per most veterinarians and health-related pet associations, taking into account the size of your dog is necessary while doing calculations. This is a formula that is very well known to and used by The American Veterinary Medical Association (AVMA).

Small Dogs (under 20 lbs)

Medium Dogs (21–50 lbs)

Large Dogs (51–90 lbs)

Giant Dogs (over 90 lbs)

Giant breeds like Great Danes, Saint Bernards, and Irish Wolfhounds age the fastest. A 10-year-old Great Dane has lived an extraordinarily full life  equivalent to nearly 80 human years.

Using a Dog Age to Human Age Calculator

To calculate the dog’s age fast and precisely, here are the steps you need to take immediately:

• Firstly, find the real age of your dog. If you rescued your pet, and you do not have information about its birth date, then you can consult a veterinarian, who can tell you how old is your dog by assessing its teeth, coat, eyes, and muscles.
• Secondly, define the category for your dog. It can be done by weighing your dog or consulting your vet. There are four categories: small, less than 20 pounds medium, between 20 and 50 pounds large, between 51 and 90 pounds giant, over 90 pounds.
• Thirdly, select the corresponding conversion. Look at the conversion table provided above in connection with the age of your dog and its category, or use an online dog to human age converter.
• Finally, interpret the results. Do not use only the numbers received. A dog aged 55 years in human terms might need additional nutrients and medical appointments, and avoid some types of physical activities.

What Does the Calculator Tell You About Dog’s Health

Now you know what that dog age calculator can do for more than entertaining purposes.

Puppy (Teens to mid-20s)

Dogs under the age of one year are going through rapid growth and development. It’s time for vaccination, socializing, and proper training. Imagine your puppy like a rebellious teenager that requires strict rules, lots of exercise, and freedom.

Young Adult Dog (Late 20s to 30s)

A dog between 2 and 5 years old will have lots of energy but won’t be hyperactive like a puppy. It’s crucial to provide healthy nutrition and professional dental care at this age.

Middle-Age Dogs (40s to 50s)

During that period of life, you can observe some changes. Perhaps your dog started eating less and sleeping more. It can also become overweight and have trouble getting up from the ground. Blood testing is essential at this age as many senior illnesses can develop.

Senior Dog (Above 60s)

Any dog over 7-10 years (depends on the breed size) is called a senior dog. Just like people need to care about themselves and take special treatment during that period, so do older dogs. They require regular veterinary examination, soft food, and ramps instead of stairs.

Breeds Have Their Own Pace of Aging:

Aging is not the same for each dog breed. Below are some examples that prove how greatly the lifespan of certain types of dogs may differ:

• Chihuahuas normally live 15-20 years, and their age equals to 10.
• Labrador Retrievers usually live 10-12 years and become senior at the age of 7-8.
• Bernese Mountain Dogs typically have an exceptionally short lifespan – 6-8 years, and even begin showing signs of aging at four or five.
• Jack Russell Terriers enjoy great longevity for a medium-size dog and are expected to live between 13 and 16 years.

The more accurately you want to calculate your dog’s age in human years using a dog age calculator, the more important it is to account for breed along with size.

Interesting Facts About Dog Aging

According to Guinness World Records, the oldest living dog was a Portuguese Rafeiro do Alentejo named Bobi, who died at the age of 31 years and 165 days which corresponds to 200 human years and change.

Just like humans, dogs experience such symptoms of aging as grey hair, cataracts, arthritis, as well as cognitive decline, similar to dementia.

There are researchers who suggest that spayed and neutered dogs have a slightly longer lifespan than those intact.

Dental hygiene is among the best indicators of longevity in dogs. Regular teeth cleaning can add years to their life.
