Size and Lifespan
The gray wolf is the largest member of the canine family. They range in height from 26-32 inches at the shoulder and on average their length is 4.5-6.5 feet from snout to tail. They can weigh from 55-130 pounds, although, male wolves are typically heavier and taller than female wolves, female wolves tend to be bigger in length.
Gray wolves can live 7-8 years in the wild or 9-11 years in captivity. There have been some wolves in the wild that have lived up to 10 years, but this is not very common.
