What does petcalc do?
Petcalc is an independent collection of free browser-based tools for dog owners. Its dog age calculator accepts an approximate age, birthday, or shelter age range and uses adult size to show human-age estimates and life stages. It also offers a puppy weight calculator and dog lifespan references by breed and size. Methods and published sources are explained on the site, and no account is needed. Results are estimates and do not replace veterinary advice.
