Question 1

How old is my dog in human years?

Accepted Answer

The old '7 years' rule is a myth. Dogs age faster in their first two years (15 + 9 human years), then 4-7 years per dog year depending on size. Small dogs age slower than giant breeds.

Question 2

Do small dogs live longer than large dogs?

Accepted Answer

Yes, small dogs typically live 14-16 years, medium dogs 12-14 years, large dogs 10-12 years, and giant breeds 7-9 years. The exact reason is still studied, but larger dogs age faster at the cellular level.
