Why do small dogs live longer?

Researchers believe that smaller dogs live longer than large dogs due to several different reasons and studies continue to determine a definitive reason. One theory is that because large dogs grow at such a rapid pace from being a puppy to adulthood it could cause abnormal cell growth which would contribute to various illnesses and conditions in later life.

A dog is a fantastic addition to any home and no matter what their expected life span is, love, care, regular exercise and a good quality diet all contribute to their overall health, quality of life and life expectancy.
