ATTENTION: These Dog Breeds Have A Life Expectancy Under 10 Years…


In a previous article, I listed long-living dogs. Here, you will find some of the dog breeds with a shorter lifespan. These tend to be larger dogs, compared to the longer-living breeds. Is your dog one of them?

The Newfoundland is equal as both companion and worker. They are strong in body, confident in the water, and natural babysitters. You may recall Nana from Peter Pan; she is a Newfoundland.

Greater Swiss Mountain Dog – 8 years

The Swissie excels in weight pulling and agility sports — he is an all-around working dog, whether standing guard, herding cattle, or pulling carts.

With a legacy dating back 5,000 years, this monstrous pooch can weigh up to 220 lbs — in fact, it’s it his size that contributes to a shorter lifespan.

Borzoi – 7 years

Another dog with a shorter lifespan is the tall Borzoi dog. They sport a variety of colors such as black, white, cream, red and fawn. Yet, due to many health problems, this gentle giant’s lifetime is limited to 7- 10 years.

Bernese Mountain Dog – 7 years 


The Berner is known for his wonderful temperament and high intelligence. Sadly, due to the breed’s small gene pool, they have numerous health problems, related to inbreeding, and struggle to survive, making our list of dogs with the shortest lifespan.

French Mastiff Has The Shortest Lifespan – 5 To 7 Years

The easy caring, French Mastiffs may be one of my favorite dogs. They are possibly the shortest living dog breed in existence with a life expectancy of 5-8 years. 

Would you live differently if your dog had a shorter lifespan?
