Frequently Asked Questions

Is 1 dog year really 7 human years?

No, the 7:1 rule is inaccurate because dogs mature rapidly in their first year (reaching roughly 15 human years) and larger breeds age faster than smaller breeds.

Why do small dogs live longer than large dogs?

Large dogs grow rapidly from puppyhood, which scientists link to increased cellular strain and accelerated physiological aging.
