We have wolf breeders (Up to 98%, due to legal reasons.) on opposite ends of this great state...they are surprisingly well-behaved. The wolves, that is.
They are amazing and beautiful animals.
I'm not sure I'd want one as a pet though. They are not the same as dogs.
I imagine it's similar to those select few who have pet grizzly bears. It can be done if you get them from birth and raise them, but even then, it's still quite risky, wild instincts and such.
