How Old Is Your Dog in Human Years? Use This Quick Calculator

To determine a dog’s age in human years, don’t just multiply your pet’s age by seven. Calculating a dog’s age is more nuanced. A dog’s lifespan depends on several factors, primarily size and breed. Small-breed dogs typically live longer, while larger breeds have shorter lifespans but mature more quickly. The average lifespan for a medium-sized dog ranges from 10 to 13 years. However, some dogs can live significantly longer.

The calculation is further complicated by the fact that dogs age at different rates during various stages of life. Experts from the British Kennel Club suggest the first two years of life for small-breed dogs equate to about 12.5 human years. For medium-sized dogs, that figure drops to 10.5 years, and for large breeds it’s around 9 years. After that, each additional year of a dog’s life corresponds to approximately 4.3 to 13.4 human years, depending on the breed. The Daily Mail has published a calculator that can help you determine your dog’s age in human years more accurately. You simply need to input your dog’s age in calendar years and its size.
