The wolf is the ancestor of the domestic dog but instead of barking, it howls. Only wolf pups make a high-pitched bark. The timber wolf has a number of subspecies found in the wilder parts of Europe, northern Asia and India, and North America.
Red wolves are very rare and are found in the south-eastern United States.
Wolves live in open country and in forests. The timber wolf is 120 to 200 cm from nose to tip of tail. It is about 75-80 cm tall and weighs between 20 and 60 kg. Timber wolves that live in northern regions tend to be much heavier than those found further south. A timber wolf looks much like a husky, that long-legged dog which pulls sleds over the snow.
