Can a dog live to 20 years? The aging profile of dogs varies according to their adult size (often determined by their breed): smaller dogs often live over 15–16 years (the max is 20 years), medium and large size dogs typically 10 to 20 years, and some giant dog breeds such as mastiffs, often only 7 to 8 years.
Is 13 years a long life for a dog? The average lifespan for medium-sized dog breeds is 10 to 13 years, with some breeds living even longer. As with small dogs, exact age ranges for medium-sized dog breeds are hard to determine, but there are general lifespan guidelines for each breed.
What percentage of dogs live past 15? Studies show that only 20% of dogs live over their 14th birthday, with fewer than 10% making it to their 15th birthday. However, not all dogs live to their full lifetime potential. There are factors to consider, such as the breed and size of the dog in question. The health of the dog also must be considered.
