Dogs and Longevity

Every dog breed has its own set of characteristics. From height and weight, fur or hair, to temperament. Large dogs are good watchdogs and guard dogs. Their size intimidates strangers. However, they eat more and thus cost more to care for. Small breeds are easy to travel with and adapt well to city living. Longevity, or life span, depends on a variety of things but is often correlated to the breed’s size.

Studies show that smaller breeds live longer than larger breeds. Specifically, small breeds tend to live between 12 to 14 years, bigger breeds typically live between 8 to 10 years, while giant breeds generally live between 5 to 8 years. This difference is largely due to characteristics on a cellular level. Large dogs age more rapidly because of the strain on their body due to their size.

This correlation is not true for all species. For instance, bears live longer than bugs, and whales live longer than fish.  Mammal cells age and decay slower, leading to longer life spans.

But whatever their sizes, your dog will always be loyal and show you love. Carefully consider your lifestyle and expectations before choosing your dog!
