All dogs are descendants of wolves, but many of today’s dog species are still directly crossbred with these wild animals. Because of the inherent danger in breeding a wild animal with a domestic one, these dogs are often extremely skittish and unpredictable, to the point that many states have made it illegal to own a wolf hybrid. The CDC determined that wolf hybrids were responsible for the deaths of 14 people in the United States from 1979 to 1998.
