How It Works
We use the modern AKC-accepted formula. The first year counts for ~15 human years, the second for ~9, and subsequent years vary by size (small dogs age slower than giant breeds).
Tips & Best Practices
- •Small dogs typically live longer than large dogs.
- •The first year of a dog's life equals about 15 human years.
- •Regular vet checkups are crucial as dogs enter their senior years (7+).
Frequently Asked Questions
Is the 7-year rule true?
No. It was a simplified average. A 1-year-old dog can reproduce, while a 7-year-old human cannot. The aging curve is much steeper early on.
