Having had and still due the oldest pedigree that is almost identical to the Nordic white wolf I can tell you they need to be out in the country. Fenced yard. They are illegal in many states. The Samoyed, Sibrian due not like loud noise especially a wolf. The gray wolf is very dangerous. Wolf's are very intelligent however they and the hybrids do not live as long as more of a domestic canine. Diet,exercise and mental stimulation is vital to all three types. I own one of the country's top grand champs who has been a wonderful producer. Originally from the Siberian Tunda. Putin uses them to guard his prisons in the tundra. The hybrid wolf was a good pet and protective but remember they still go after any animal and will kill them around their territory.
