Have you ever wondered how old your dog is in human years?

It’s not as simple as 7 years to every 1 human year, as science has shown dogs age more rapidly during the puppy phase, and size and breed will also affect the dog years to human years ratio.

Understanding your dog’s age in relation to our own can provide valuable insights into their health, behavior, and overall wellbeing.

That’s why we’re excited to introduce our advanced Dog Age Calculator!

The dog age calculator will provide you with a good estimate of your dog’s age in human years based on their current age and size of breed.

You will also find a reference table below to show how the human age equivalents vary for different dog breeds and sizes.

    Why is 17yrs an invalid age for a medium breed dog?

      Hi Diana, ah the age calculator isn’t perfect! Best we can do with the knowledge we have, but yes you’re right – even 25 should be a valid age for a medium dog 😉
