Frequently Asked Questions
Is the one dog year = seven human years rule accurate?
No. The AKC and scientists now recognize that the formula varies by breed size. Small dogs age slower than giant breeds. Our calculator uses size-adjusted tables for more accurate results.
What counts as a "small" dog?
Small dogs are generally under 20 lbs (9 kg) at adult weight. Examples include Chihuahuas, Shih Tzus, and Toy Poodles.
