Frequently Asked Questions
- Is one dog year really seven human years?
- No, that is a myth. Dogs age fastest in their first two years — a 1-year-old dog is roughly 15 in human years and a 2-year-old is about 24. After that, the rate depends on size.
- Do small dogs live longer than large dogs?
- Yes. Small breeds typically age more slowly after maturity, while large and giant breeds age faster and have shorter average lifespans.
