The largest of the great white mountain dogs of Central Europe, the Tatra Mountain Sheepdog (Owczarek Tatranski) is a classic flock guardian, although it was also used occasionally to pull carts. Independent by nature, it can become firmly attached to humans when raised from puppyhood as a canine companion. Its popularity, in Poland in particular, but also elsewhere in Europe and North America, has soared dramatically in the last 15 years.
