One thing about dogs that fascinates me the most is the differences in lifespans between dog breeds.
At 29 years of age, the Australian Cattle Dog name Bluey is the oldest living dog, passing away in 1939. However, a study regarding longevity in Australian Cattle Dogs showed that most Australian Cattle Dogs live, on average, 13.41 years. Although Australian Cattle Dogs live longer than average, it’s not the longest living breed of dog.
As for the longest living dog breeds, these breeds are amongst the average longest living: Toy Poodle 14.67 years, Miniature Dachshund 14.4 years, Canaan Dog 14.67 years, Swedish Vallhund 14.77, Border Terrier 14 years, and Cairn Terrier 14 years.
The Dogue de Bordeaux, or French Mastiff, has the shortest life span of 5.29 years. Other breeds like the Irish Wolfhound and Bloodhound have an average lifespan of around 7 years.
The British Veterinary Association compiled results of a survey by dog owners who gave information about their deceased dogs, resulting in information from 3,000 dogs.
From the abstract of the article: “The mean age at death (all breeds, all causes) was 11 years one month, but in dogs dying of natural causes it was 12 years eight months. Only 8 per cent of dogs lived beyond 15, and 64 per cent of dogs died of disease or were euthanased as a result of disease. Nearly 16 percent of deaths were attributed to cancer, twice as many as to heart disease.”
If you are interested in more information regarding breeds and their average life spans, you might want to check out Dog Longevity created by Dr. Kelly M. Cassidy. On the site you will find information on life spans of dog breeds, including information from the US, Canada, and the UK. You will probably notice some variance in breed life span between the different countries. I would attribute this to statistical noise and probably not habits of dog owners by nation. None of the differences in life spans between the countries seems to be statistically significant.
I realize there is so much more information that could be covered but, I just wanted to give you all a brief overview of dog breed longevity and some interesting facts. There is just an overwhelming amount of information and a multitude of variables when it comes to the life spans of all the different breeds of dogs. Selective breeding has given us a wide variety of dogs and a wide variety of health concerns for these dogs. Future posts about health issues, selective breeding, designer dogs, diet and other posts will hopefully provide more information about the life spans of our dogs.
Do you have any stories about the life span of your dog or a dog you know? Any anomalies you have witnessed in the age of a dog?
