Shortest-living dog breeds

Everyone from grade school students to proud pet owners quotes the statistic that one dog year equals seven human years. It's considered axiomatic. But, as it turns out, that's not accurate. Really, experts say, it's more accurate to compare the first year of a dog's life to 15 years of a human's life, the second year to nine human years, and every year after that to five human years.

The math gets still more complicated when the size of the dog is factored in: Bigger dogs start to age faster than small dogs around 6 years old and the gap increases by year eight. This relationship between body mass and age expectancy baffles scientists. Normally, the larger the mammal, the longer it lives. Yet for every 4.4 pounds of body mass, a dog’s life expectancy is reduced by about a month. Theories why abound, from age-related illnesses affecting big dogs sooner to a higher likelihood of abnormal cell growth and death from cancer because of the sped-up growth of large dogs. 

Regardless of how you calculate it, the truth remains that our canine companions won't live anywhere near as long as our human friends. However, some breeds have longer average lifespans than others. To find out which dogs tend to live the shortest lives, Stacker used data from a study published in the journal Genetics and the American Kennel Club dog breed popularity rankings to rank 50 breeds based on their average lifespans. Only breeds recognized by the AKC were considered. When several breeds had the same average lifespan, Stacker used popularity rankings to break the tie.

Read on to find out which large breed lives just over six years on average, and which small dogs can live an impressive 11-plus years.
