The Science Behind Pet Aging

The old "1 dog year = 7 human years" rule is a myth! Pets age much faster in their first few years of life, then the aging process slows down.

For dogs, size matters too. Smaller dogs tend to live longer and age more slowly than larger breeds. A Great Dane is considered "senior" at 6 years old, while a Chihuahua might not reach that stage until 10.

Cats age similarly regardless of breed—about 15 human years in their first year, 9 more in their second year, then about 4 human years for each year after that.

Our calculations are based on guidelines from the American Veterinary Medical Association and recent research on pet aging.
