There are dogs that can climb trees, cat-like bend back and even "sing"

We are talking about the New Guinea Singing Dog (Canis lupus hallstromi), considered to be one kind of wolf scientists, and others - view of feral dogs. Externally, these dogs resemble the ordinary, but they are very small: the growth of males is not more than 40 cm at the withers, weight - 10-14 kg (females is even lower and easier).

Habitats of these animals are considered to be forests of New Guinea, at least it was there they discovered in the twentieth century. Biologists believe that this breed is much more ancient history - people have used for centuries singing dogs for hunting, because they are very intelligent and have specific skills. For example, in the New Guinea dogs howl a very unusual manner, to distinguish them from coyotes, wolves and other colleagues - it is more like birds singing than usual barking, howling with the New Guinea dogs, usually simultaneously. In addition, they are inferior to domestic breeds in running speed and endurance, but they have a flexible skeleton, and they're very agile - it allows them to climb trees like cats jumping through the barricades and even hog.

See the New Guinea Singing Dog is possible in some zoos of the world: living in captivity, they quickly become accustomed to the man, although in the wild, these dogs almost imperceptible.
