Longevity is the ability to maintain vital body functions longer, minimizing the effects of external changes. We say that a dog is long-lived when it lives longer than the average life expectancy of similar specimens. Dogs manage to live more years when all the functions of their body remain optimal for longer, resisting the natural process of aging. The latter is a natural process of changes and adaptations throughout their life cycle.
The longevity of a dog depends on intrinsic factors, mainly genetic, and extrinsic agents that can be controlled to counteract the effects of aging. Nutrition, exercise, and the care given to a pet are all factors that affect the duration of their life.
Do dogs really age 7 times faster than humans?
A dog’s size determines the age at which they reach adulthood as well as when the signs of aging begin to appear, therefore longevity is related to size.
With smaller breeds at one end of the longevity scale and larger breeds at the other end, the popular belief that a “dog year” is equivalent to 7 human years is not always true.
There are exceptions to the rule and some dogs insisted on overcoming these parameters, thus going down in history as the longest living dogs.
The 10 Longest Living Dogs
Although it was never officially confirmed, a dog named Chilla seems to be the longest living canid in history, reaching 32 years and 12 days. Genetically, Chilla was a mixture of Labrador and Australian Cattle Dog, which triggered a research on the special characteristics of the Australian Cattle Dog to stay healthy and live longer than dogs of breeds with similar size and characteristics.
