How Long Do Mixed Breed Dogs Live?
For mixed breed dogs, owners can use an individual’s weight to help determine how long he or she would be expected to live. In general, small dogs enjoy longer lives than do their larger counterparts. A recent analysis of veterinary records revealed that dogs under 20 pounds had an average lifespan of 11 years while those over 90 pounds typically lived for only 8 years. Medium and large dogs fell in the middle at around 11 years. (State of Pet Health 2013 Report, Banfield Pet Hospital).
But average life expectancy isn’t the whole story. The very definition of “average” means that many individuals will have shorter lifespans while others can be expected to live much longer than the norm. Perhaps a better way to evaluate a dog’s longevity is to convert “dog years” into “human years.” In this way, we can understand just when a dog is an adult, a senior citizen, geriatric, or the equivalent of a human centenarian.
Information about a dog’s expected lifespan won’t help blunt the pain of his or her loss, but it can help owners plan how to best care for their companions during the time we do have together.
Humans have much longer lifespans than dogs. This is a basic fact of dog ownership and one that many owners struggle with when the time comes to say goodbye. While we may wish our dogs could live forever, knowing how long dogs live helps prepare us for their needs as seniors, ensuring that we give them the best possible care throughout their lives so that we get to spend as much time with them as possible.
There are several factors that determine the longevity of dogs, including size, breed, and the general health of the animal. These factors can help answer the questions on most dog owner’s minds: How long do dogs live? And how can I help my dog live longer?
10 Dogs With Short Life Expectancies
You’ll notice that most dogs in this chart are larger breeds. As mentioned above, larger dogs tend to have shorter lifespans than smaller ones. Some believe this is because large breeds age more quickly. For example, a Great Dane can gain 100 pounds from its day of birth to its first birthday, whereas a Shih Tzu can weigh up to 15 pounds in its entire lifespan. Below is a table of 10 dogs with short lifespans.
|Dog Breed||Average Lifespan|
|French Mastiff||5-8 Years|
|Great Dane||6-8 Years|
|Bernese Mountain Dog||6-8 Years|
|Irish Wolfhound||6-10 Years|
|Neapolitan Mastiff||7-9 Years|
|Saint Bernard||8-10 Years|
|Scottish Deerhound||8-10 Years|
