It's sad that people are allowed to own wild animals. Actually, disturbing...
This animal doesn't belong in a house. In a yard. In a neighborhood. That animal, regardless of how gorgeous it may be, is WILD. Not feral, WILD. It's sad he's been hand reared... even so, should not have to be confined to just a yard for the rest of his life. And on a chain? Sorry, but that's cruel and inhumane - especially to a wolf. This goes for any wolf hybrid too...
Someone needs to take it from them, if they plan to keep it that way. They need to realize what they are doing, and get a dog. All a dog is, is a domesticated wolf. Tell them to get a malamute... they look simular.
