Average Life Expectancy of Dogs

after researching some dog breeds for "average life expectancy" i found this site that i thought was interesting http://www.pets.ca/pettips/tips-46.htm ; it took me a minute to find collie as it's listed as rough collie (smooth's do have the same life expentancy) and of course we all know some dogs that have lived longer or shorter lives---but this site seemed more accurate than some i encountered that said collies live to be 13 to 16 years, german shepherds 12 to 15 years and dobermans 12 to 15 years . (all dogs i have studied and knew better). if you go down the page of the link it has many interesting tips on dogs and cats also.

Life expectancy in dogs - How long will my dog live?

We all want our pet dogs to live as long as possible, but the fact of the matter is that on average, certain dog breeds live longer than others. This might be a consideration when choosing a dog breed and it is therefore useful information to know before hand.
The average life span of the North American or European dog is 12.8 years. This is a large increase in life span over the past 100 years and is mostly attributable to better food and better medical care. Within this 12.8 year average for all dogs is a large range of life spans where certain breeds live longer and certain breeds live less long. In general, larger dogs live shorter lives than smaller dogs. This is due to the fact that the bodies of larger dogs must work harder (are more stressed) than the bodies of smaller dogs. That said, the life expectancy of any one dog in particular is ALSO determined by the stresses in its life (both physical and psychological), what it eats and how well it is taken care of.
