A true beauty, the most common variety of the the Caucasian Mountain Dog, is called the Ovcharka. They are most popular in places like Russia and Azerbaijan. They are also found in the Mountaneous country of Armenia.

Due to their heavy coat, the Ovcharka is capable of withstanding severe cold, and is primarily used to guard livestock. Often used to guard sheep, the sheer size and potential aggressiveness (When their family or stock is threatened) is a suitable deterrent against predators.
