If you ever wondered if your dog is still a rebellious teenager or a respectable pensioner, this dog age calculator might be right up your alley. It is a tool that lets you recalculate dog years into human years for any dog breed. (Spoiler alert: a year in your buddy's life is not equivalent to seven human years.) Thanks to this calculator, you will learn how to count dog years in no time!

Dog year calculator principles

Unfortunately, there is no one simple formula to allow you to quickly convert between dog and human years. Puppies grow up faster when they're still young, and they age slower once they reach maturity. Hence, the first year in a dog's life is always equivalent to 15 human years, but for older dogs, one year is only like 4 or 5 human years.

The second thing that you have to take into account is that small breeds tend to live longer (and hence age slower in the big picture). In general, dog breeds can be divided into three types that age at a different speed:

  • small: 20 lbs or less (when fully grown)
  • medium: 21-50 lbs
  • large: above 50 lbs

Our dog age calculator takes into account only dogs below 20. We know that older dogs have made the Guinness World Records, but they were exceptions - regular dogs don't live that long.

How to count dog years

  1. Begin by researching your puppy's breed. If it's a mongrel, you don't need to know the exact breed, but you should know how big will the dog grow.
  2. Choose whether your dog is small, medium, or large. Choose the appropriate type from the list.
  3. Enter the current or expected age into the dog age calculator.
  4. You will obtain a result - the number of human years that correspond to your dog's age.

Things to consider

Think about a control visit at your doctor. How often do you go to get yourself examined? Every two years? First two years of a dog's life are like 24 human years. Can you imagine going to see a doctor only once during that time?

Remember to take your dog to a veterinarian much more frequently than you go to a doctor. Twice a year is an absolute minimum!
