the coolest however have got to be labs.
Labs are great. One of my all time favorite dog is the lab/pit
mix. The playfulness of the lab mixed with the intensity of the pit makes for fun times. However, you need to be a responsible pet owner to own one imo, and unfortunately there are too many pet owners who are not.
I'm not sure about the breeding of wolfs with dogs, but a friend of mine says one of his cat's is half bobcat. It's a huge cat, but I couldn't say 100 it is or is not. If it is doable, then yeah you could make some monstrous home pets.
