DogAge is a new website that calculates your dog's age in people years using a series of questions about your dog's health, breed, birthdate, lifestyle, and feeding habits.

Historically, people figured that they can calculate a dog's age in people years by multiplying its actual age by 7. But DogAge goes about it a different way by gathering information specific to your dog.

I ran through the calculator for our Beagle "Mia". We don't really know when she was born, because the rescue group we adopted her from found her as a stray. But they seemed to think she was born around October of 2003. So I used that as her actual birthdate. After running through all the questions, it calculated her "people age" at 10.4 years, claiming that she was 4.1 years younger than the average Beagle. The younger, the more healthier she is presumed to be, and the longer she's expected to live.

DogAge is produced by the folks at RealAge, a publisher of books, and media relating to healthy living. The DogAge calculator was created by Dondi Dahlgaard, DVM, who has written a book by the same name, "DogAge".
