What Is a Dog Year?
A dog year refers to one calendar year in your dog’s life. Because dogs age at a very different rate to humans — especially in their first two years — each dog year carries a different human-equivalent value. Our dog year calculator tells you exactly which year of life your dog is in and what it means for their health and care.

FAQs
Is 7 dog years 1 human year?
No — this is the reverse of the common myth. 7 dog years equals approximately 44-62 human years (depending on size). 1 human year is not equivalent to 7 dog years in any meaningful sense.
How old is my dog in dog years if he is 5?
A 5-year-old dog is in their 5th dog year, which equals approximately 38-47 human years depending on size. Use the calculator above for your specific dog.
