Frequently Asked Questions
Why isn't 1 dog year equal to 7 human years?
Dogs mature much faster in their first two years. A one-year-old dog is roughly equivalent to a 15-year-old human, and the rate varies by breed size.
Do small dogs age differently than large dogs?
Yes. Small breeds tend to live longer and age more slowly after maturity, while giant breeds age faster and have shorter lifespans.
