Attacks by wolf-dog hybrids on people and livestock may lead people to expect similar behavior from wild wolves and hamper wolf recovery. Hybrids seldom survive long in the wild. A wolf has very well developed senses. It can hear a rodent moving under heavy snow cover and other wolves howling from several miles distant. It can smell prey that is more than a mile away.
Wolves run on their toes.
This lengthens their legs and makes it possible for them to run faster and turn more quickly. There are probably fewer than 2,500 wolves in the entire United States today, outside of Alaska. Most of them occur in Minnesota and neighboring states, though a few occur in the northern Rockies and the northern Cascades. All dogs are descended from wolves that were tamed in the Middle East about 12,000 years ago. A wolf's winter coat is very wooly.
