Aging in Dogs - It's a Mystery

In mammals, the general longevity rule is that the larger the mammal, the longer it lives. For example, elephants live about 65 years, and rodents only about four.

But in dogs, it's the opposite. The smallest breeds live more than twice as long as the largest breeds.

The aging contradiction in dogs is a mystery waiting to be solved. That's why Cornell University, in collaboration with schools across the country, is creating the first research network to study canine aging with hopes of applying findings to questions about human aging.

Cornell's Adam Boyko, assistant professor of biomedical sciences, and his colleagues will lay the groundwork for a nationwide Canine Longitudinal Aging Study (CLAS) to find out how a dog's aging process is shaped by genes and environment. Read more about the study here.

I interviewed Adam Boyko about a different study, The Village Dog Genetic Diversity Project, published in the 2013 summer issue of The BarkScientists Searching for Clues to the First Dog: Village dogs' genetic code may hold clues to canine evolution and health.  It seems like Dr. Boyko is always asking the most interesting questions.

  1. I saw that recently with large breeds living less years and it made me think I might prefer a smaller dog, losing a pet is hard enough but hate the thought of such a short time with a loved pet.
