Dog Years to Human Years
The Average Lifespan of a Dog
Working out dog years to human years for your pooch depends on his expected lifespan, which varies from breed to breed, and can be lengthened. More about that later, but for now, let’s assume you don’t know your dog’s breed and you just want a rough idea of dog years to human years.
Dog’s mature more quickly than humans in the first year of their life, so the first year of your dog’s life (in human years) is equal to 15 dog years. So if you have a one-year-old pooch, he will be a 15-year-old teenager to other dogs.
Dog Years Calculator
- The average lifespan of a dog is 11.5. This is the average of all breeds put together.
- The average lifespan of a human is 78.
- That gives us 6.7 dog years to human years (round it up to 7 if you want to simplify the math).
In other words, if your dog is 5 years old (in human years) he is almost 35 years old in dog years.
How Long Do Dogs Live?
The average lifespan of a dog varies from breed to breed, with the smallest breeds living longer than the large breeds. For example, the Chihuahua lifespan is around 16 while the Great Dane lifespan is only around 9 years. But the average lifespan of a dog can be lengthened.

Factors Affecting Dog Lifespan
Pet obesity is an epidemic across developing nations. This is alarming because research has shown that obese dogs live 2 years less than dogs at a healthy weight. Obesity increases the risk of many diseases that not only shorten your dog’s life, but diminishes the quality of his life, too.
Keeping your dog at a healthy weight reduces the risk of his developing weight-related diseases, improves his quality of life, and gives him a chance to live out his full life expectancy.
Trauma, cancer, congenital disease and infectious disease are other factors that can affect your dog’s lifespan. Cancer is the leading cause of death in large dog breeds, particularly Golden Retrievers, and studies are underway to discover why this is the case.
