A wolf-dog is a cross between a pure wolf and a dog or another wolf dog hybrid, usually Malamutes, Huskies and German Shepherds.
Hybrids tend to be heavier and taller that wolves.
There are many myths about wolf-dog hybrids, some are about them being viscous and untrainable, others say they are as docile as the family golden retriever, as with dogs each animal is different, some are good and some are not. That said, the wolfdog being a cross between a wolf and dog needs special training and a person with dedication. People have to understand that a wolf-dog is still part wild, it will never be the docile family pet, these animals have special needs, both physical and mental. Most People, once they learn the truth about wolves and thier true nature- will sometimes want to go and purchase a wolf pup. They see the wolf as a tangible symbol of the wilderness, they envision movies like white fang , and have misplaced ideas about helping an endangered species by keeping one as a pet.
