What’s the Latest Math? – Dogster

You’ve heard the old saying — to calculate your dog’s age in human years you multiply his age by seven. A more modern idea accounts for breed size, where small and medium-sized breeds are thought to age at a slower rate than large and giant breed dogs.

All mammals progress through the life stages of embryonic development, birth, infancy, youth, adolescence, adult and senior, but not at the same rates. The new math for determining how old a dog is in human years changes our perception of just how old our dogs are.

The latest research on converting dog years to human years

In a study published by Cell Systems, researchers from the University of California San Diego School of Medicine, along with leading veterinarians, formulated a new way for determining age in dogs that, pending further research, works for multiple dog breeds.
