When people think of wolves, one species usually comes to mind: the gray wolf. The gray wolf is the largest wolf and the basis of legends. According to National Geographic, the breed was almost hunted to extinction in the lower 48 states of the United States. Even now, few exist outside Alaska.
The largest wolves are Arctic wolves and Gray wolves. They are both 4 - 7 feet long and weigh 175 - 176 pounds at average and also weigh over 200 pounds. The largest wolf everâ¦ that I have heard of was shot and weighed 240 pounds, though that record has not been published on websites or books.
