When does a pet become “old”?

It varies, but cats and small dogs are generally considered geriatric at the age of 7. Larger breed dogs tend to have shorter life spans and are considered geriatric when they are approximately 6 years of age. Owners tend to want to think of their pet’s age in human terms. While it is not as simple as “1 human year = X cat/dog years”, there are calculations that can help put a pet’s age in human terms:

Age: Human Equivalents for Older Pets

7 45
10 58
15 75

Dog years Human years (*dog size lbs)

Large – Very large: 50-56
10 Small – Medium: 56-60
Large – Very large: 66-78
