Calculate your dogs age Chart

Have you ever found yourself wondering how old your dog is in people years? With this simple formula, it's now easier than ever to calculate your dog's age! Find out how old your furry companion really is today.

Consider their Breed, Size, and Health.

Before you can accurately estimate your dog's age in human years, it is important to factor in elements such as their breed, size, and overall health. Smaller breeds tend to live longer than larger breeds and those breeds with a genetic predisposition for certain illnesses may age faster than other dogs. A huge pup might age more slowly at first, but be nearing middle age at 5. Tiny and toy breeds don't become "seniors" until around age 10. Medium-sized pooches are somewhere in the middle on both counts. Large breed dogs tend to age faster than small breed dogs.

How to calculate the age of your dog Chart

To get the most accurate estimate of your pup's age in human years, use the formula 2 x (your dog's age) + 21.

This will give you a starting point that can then be adjusted depending on your pup's breed, size, and health. For instance, smaller breeds may add an additional year per every three or four dog years while larger breeds may subtract a year per every three or four years.

Additionally, if your pup has an illness that requires specialised care due to their breed type, you may want to factor in more time than the standard calculation.

Acquaint Yourself with Life Stages and Draw Conclusions.

It's important to remember that dogs go through a number of life stages and experiences. By understanding these stages and applying the formula, you can draw conclusions regarding your dog's age in human years. For example, puppies reach maturity around nine to twelve months old - this is equivalent to approximately 15-20 human years. Adult dogs live eight to twelve years depending on size and breed - which is equivalent to 56-80 human years. Senior dogs are commonly seven years old or more - roughly equivalent to 77 human years.


Convert dogs age in human years

If you've adopted a puppy or dog but don't know their history, you may not know how old they are. Even if you don't know the birth date, you can still guess their age. Their teeth should give you a rough idea of their age. These guidelines will vary from dog to dog, and they also depend on the kind of dental care (if any) they had before you got them.

8 weeks:All baby teeth are in.

7 months:All permanent teeth are in and are white and clean.

1-2 years:Teeth are duller and the back teeth may have some yellowing.

3-5 years:All teeth may have tartar buildup and some tooth wear.

5-10 years:Teeth show more wear and signs of disease.

10-15 years:Teeth are worn, and heavy tartar buildup is likely. Some teeth may be missing.

Your vet can also guess their age based on a complete physical exam or tests that look at bones, joints, muscles, and internal organs. Senior dogs might show some specific signs of aging.

Calculate Aging with a Multiplier Based on their Average Lifespan.

To accurately estimate your dog's age in human years, use this simple formula based on the average lifespan of different breeds: divide the age of your pup in years by their average lifespan. Next, multiply that number by the total number of human years they typically live.

This formula provides a more accurate estimation of your dog’s true age and helps you determine how much time to spend with them, as well as when it is time for regular checkups.
