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.

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.
