Wolves are not dogs and rarely make good pets. *Some* wolf-dog hybrids can make good pets but it is really sort of a toss up on temperament. Dogs have been selectively bred to be compatible with humans for as much as 30,000 years. (according to most recent discoveries) Wolves are aggressive, dominate (even with other pack members) and do not form the connection with humans that dogs do. You will never be able to expect it to act like a dog. if you want see a GREAT show about dogs that contains a segment about the differences between dogs and wolves check out Nova's "Dogs Decoded" it is avail on Netflix streaming, :) Also a full blooded wolf could never be truly happy in captivity they need to be able to roam, run free and hunt. The very things most people admire about wolves is the very thing you would be squashing by keeping them confined.
Dogs are bred domesticated for centuries and generally safe to be around humans and other pets. Wolves are WILD ANIMALS and not safe to be around people as they ARE NOT DOMESTICATED!!!!!! Like any wild animal, even if raised in captivity as a pet, they remain wild animals genetically there is always a very strong chance that something could suddenly trigger a wild animal reaction and you or a family member or friend could find their throat ripped out. Wild animals cannot be completely tamed and forever remain unpredictable.
In most places a wolf is considered an exotic pet and so is illegal to own, plus many wolf species are endangered and so doubly illegal to own.
