The typical lifespan of dogs varies
considerably by breed. For example,
many giant dog breeds average only 7 or
8 years, while some small terrier
breeds might live as long as 20
years.
The average lifespan for mixed-breed
and midsize dogs is about 13 to 14
years.
The longest-lived dog with reliable
documentation died at 29 in 1939.
Although the lifespans of all living
species are mostly uncontrollable, one
can significantly extend a dog's life
by feeding it the right kinds of foods,
giving it exercise, visiting the vet
frequently, caring for its special
needs, and loving it.
