Since the 1930s, the canine life span has increased more than 70 percent, from seven years to 12! And that's just the average. With advances in veterinary care and nutrition and more knowledgeable owners, many good-sized dogs now live to 14. Of course, no one can really predict how long an individual dog will live.
The aging profile of dogs varies according to their adult size (often determined by their breed): smaller dogs often live over 15â16 years, medium and large size dogs typically 10 to 13 years, and some giant dog breeds such as mastiffs, often only 7 to 8 years.he mean age at death (all breeds, all causes) was 11 years and 1 month, but in dogs dying of natural causes it was 12 years and 8 months. Only 8 percent of dogs lived beyond 15, and 64 percent of dogs died of disease or were euthanized as a result of disease.
