The Polish Tatra Sheepdog is a breed of dog introduced into the Tatra Mountains of Southern Poland by Vlachianshepherds.
Tatras are primarily considered livestock guardian dogs. Their instinct, through hundreds of years of breeding, is to protect livestock, though they easily adopt a family as a flock. They are a good companion dog as well as a protection dog. They are not an attack dog, but rather move threats away through intimidation. They have a loud bark. They are not all that similar in temperament to their Mountain dog cousins the Kuvasz, Great Pyrenees or Maremma Sheepdog. They are less aloof than the other breeds, tending to be better tied into their breeding and not as domesticated or inbred as some of their cousins.
In the USA the Tatra sheepdog is considered a rare breed. It is not recognized by the AKC.
