How old is your dog in human years? We used to multiply a dog’s age by seven; however, this calculation isn’t so cut-and-dried. See our dog calculator and chart to discover your dog’s age.
The Easy Calculation of Dog’s Age
The easy way to calculate a dog’s age is to take 1 dog year and multiple it by 7 years. This is based on an assumption that dogs live to about 10 and humans live to about 70.
For example, a dog which is 5 years old is 35 “human years.” This isn’t a bad way to go from a health perspective because it helps us humans realize that our dogs aren’t the same as children.
As pets get older, they need extra care and attention. Small dogs are generally considered “senior” at seven years of age. Larger breeds are often senior when they are 5 to 6 years of age.
Be aware of arthritis and related discomfort or irritability, weight control, sight and hearing issues, and any changes in behavior or activity which could indicate more serious issues.
Visit your vet for exams regularly; adjustments can be made to give your pets a more comfortable, longer, healthier life.
The More Accurate Calculation of Dog Years
Statistics from pet-insurance companies, breed-club surveys, and veterinary hospitals have helped us learn more about how dogs age.
Dogs do not age at a rate of 7 human years for each year in dog years.
According to the American Veterinary Medical Association:
- The first year of a medium-sized dog’s life is 15 years of a human’s life.
- The second year of a dog’s life equals about nine years for a human.
- And after that, very human year equals approximately five years for a dog.
In other words, the number of human years piles onto a dog’s life more quickly during the dog’s rapid growth to maturity.

If we think like a dog, here’s how a dog’s age compares to a human’s age! There are differences between a dog’s size (small, medium, large) and a dog’s breed, but this should give you a good sense of where your dog is in the development/aging process.
