Wolves can indeed be dangerous but I hav one purebred male wolf and he is the sweetest dog ive ever had.

It depends on what state you live in, and if the wolf is purebred. Some states forbid wolves and hybrids. If your wolf is pure, you must buy a $100.00 license, and take wildlife classes. You'll also need to renew the license EVERY year

Actually, They are averagely 3.0-3.5 Feet Tall At the Shoulder.
