About Borzoi aging
The Borzoi is a large breed with a typical adult weight of 60–105 lbs and a life expectancy of 9–14 years. Because aging speed tracks body size, this page uses the large-breed rate — a middle rate.
Frequently asked questions
How do you calculate a Borzoi's age in human years?
As a large breed, the Borzoi ages at the large-breed rate: about 15 human years in year one, 24 by age two, then roughly 5.5 human years for each dog year after that. Enter an age above to see the exact figure alongside the UCSD epigenetic estimate.
How long do Borzois live?
The typical Borzoi life expectancy is 9–14 years. Keeping your dog at a healthy weight, staying current on veterinary care, and dental hygiene are the biggest levers on the high end of that range.
When is a Borzoi considered a senior?
Large and giant breeds like the Borzoi reach senior status early — around age 6–7. Senior care means more frequent vet checks and often a diet adjustment.
