About Yorkshire Terrier aging
The Yorkshire Terrier is a toy breed with a typical adult weight of 4–7 lbs and a life expectancy of 11–15 years. Because aging speed tracks body size, this page uses the toy-breed rate — the slowest, which is why small dogs often reach 15+.
Frequently asked questions
How do you calculate a Yorkshire Terrier's age in human years?
As a toy breed, the Yorkshire Terrier ages at the toy-breed rate: about 15 human years in year one, 24 by age two, then roughly 4 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 Yorkshire Terriers live?

Smaller breeds like the Yorkshire Terrier typically enter their senior years around age 8–10. Senior care means more frequent vet checks and often a diet adjustment.
