Dog Size and Life Expectancy

Do small dogs live longer than large dogs?

Q. I've heard that small dogs live longer than large dogs. Is this true? If so, why?

A. It is true that the small, or toy, breeds live longer. The Chihuahua, for example, has a life expectancy of 16 to 18 years. The larger the dog, the shorter its life. Great Danes rarely live more than 8 years. In the simplest terms, there is less strain on the organs (liver, heart, lungs, etc.) of a small dog to keep it alive and much more strain on those of larger dogs.

What about a Pug with it's pushed in snout and breathing problems. I monitor my 6 year old Pug's health and most people can't tell how old he is. I exercise him and belong to a Dog Club where we meet each Monday and do obediance training. I know I take good care of him and that plays a tremendous role in their lifespan but I was just wondering if there were any facts on pugs.

Thought the article gave me very minimal information about my question, however did answer what I wanted to know. Guess my problem is that my dog possibly has cushings now so I'm wondering about that - by the way my dog is a pompoo.
