Want to insure that your dog gets the best care regardless of its age? A comprehensive pet insurance plan is the best way to do just that!

A dog has, on average, a life expectancy of between 12 and 15 years. This varies depending on the dog's size, breed, lifestyle, general health, etc.

Do you want to know how old your dog is in human years?

Our dog to human age converter above lets you do this calculation in just seconds.

How to calculate dog age in human years

It's very simple, just use our dog to human age converter above.

Firstly, you select the category your dog comes under, and then our calculator instantly converts your dog's age into human years.

In order to estimate, in your head, how old your dog is as a human, take into account that a dog ages:

  • 15 years for the first year after birth
  • 6 years for the second year
  • 4 years for each addition year

Another commonly accepted rule for performing a quick dog to human age calculation is to multiply your dog's age by 7. However, this is a rough calculation that does not take into account any criteria specific to the dog (breed, size, lifestyle, etc).

What is my dog's life expectancy?

An average dog has a life expectancy of about 12 to 15 years. However, several different criteria come into play, in particular:

  • Size
  • Breed
  • Lifestyle habits
  • General state of health

Good to know

Smaller dog breeds tend to live longer on average than larger dogs, as you will see in the chart below. A poodle, for example, will live longer than a Great Dane.

How do I help my dog to live longer?

Veterinary medicine has evolved enormously in recent years. More and more dogs are living longer.

However, you can also, on your part, extend the life expectancy of your dog by making simple changes. Like humans, dogs also need a healthy lifestyle and in particular:

  • A balanced diet adapted to your pet (avoiding diabetes, obesity etc.)
  • Daily physical activity (walking)
  • Regular and appropriate care (vaccinations, sterilization, etc.)

Good to know

Note that neutering and spaying can prevent cancers and can extend the life of your pet.
