How the Labrador Retriever ages
The Labrador Retriever is a large dog weighing about 55–80 lb, with a typical lifespan of 13–14 years. Like all dogs, the Labrador Retriever matures fast early: about 15 human years by age one and 24 by age two, and then ages more quickly after that. A 5-year-old is roughly 42 in human years, and a 10-year-old about 72. This size-adjusted method reflects how large dogs actually age, rather than the flat "multiply by seven" rule, which overstates the age of young pets and understates senior large breeds.

Frequently asked questions
How old is my Labrador Retriever in human years?
Enter your Labrador Retriever's age above. As a guide, a large dog is about 15 at 1 year, 24 at 2, and 60 by age 8.
Do Labrador Retrievers age faster than smaller dogs?
Yes. Larger dogs age faster after year two and have shorter lifespans. That's why we adjust the curve by size instead of using ×7.
