How to Calculate Your Dog's Age?

Your dog's age can be calculated based on several factors, including their weight. Contrary to popular belief that one year equals seven human years, this method isn't accurate. Dogs age faster during their first years, then the pace slows, and it varies by size.

  • The first year of a dog's life corresponds to about 15 human years.
  • The second year is equivalent to about 9 human years.
  • From the third year onwards, each additional year equals 4 to 8 human years, depending on the dog's weight.

Use Our Calculator to Find Your Dog's Real Age

With our interactive calculator, you can easily determine your dog's real age based on their human age and adult weight category. Dogs are classified into three weight categories, which influence their aging process:

  • Under 15 kg: Small breeds, such as Bichons or Dachshunds, age more slowly after their second year.
  • Between 15 and 40 kg: Medium-sized breeds, like Labradors or Bulldogs, have a moderate aging pace.
  • Over 40 kg: Large breeds, such as Mastiffs or Great Danes, age faster.

For example, a 5-year-old dog weighing less than 15 kg would be about 36 in human years, while a dog of the same age weighing more than 40 kg could be as old as 49.

How to Calculate Your Cat's Age?

For cats, the first year corresponds to about 15 human years, and the second to about 9 years. After that, each additional year is equivalent to 4 human years.

Example: A 3-year-old cat would be about 28 in human years.

Cat Age Specifics

  • Indoor vs. outdoor cats: Indoor cats tend to live longer than those that spend a lot of time outside.
  • Breed and care: Some cat breeds live longer, especially with proper care.
