How Long Will My Dog Live?

Lifespan chart below:


That’s a Question All Pet Owners would Like An Exact Answer To

Unfortunately there is no exact answer to how long will my dog live. General references indicate the life expectancy of the Canis lupus familiaris (Dog for most of us) to be 13 years in average. However averages are averages. History tells us  the oldest living dog (documented by The Guinness World Records) lived 29 years. The dog was Bluey – an Australian Cattle Dog.

Every Dog owner would love their dog to live as long as Bluey, however genetic characteristics will predominantly determine how long pooch will be by our side. Size, weight and heredity for the most part will determine longevity. 

It is also true that dogs in modern times are exceeding their average lifespan due to the fact pet owners are giving them a more preponderant position within the family, leading to better lifestyles conditions and preventive health care practices.

Size is a significant determinant in life expectancy. Giant breed such as Mastiffs, Saint Bernards and Great Danes are known to have a 6 to 8 year life span while smaller “Chihuahua” sized dogs can extend this limit close to 20 years of age. Keep in mind however that even size is relative in determining longevity.
