The Caucasian Shepherd, also known as the Caucasian Ovcharka, is a massive breed that can weigh up to 200 pounds. For someone unfamiliar with such large dogs, this size alone can be overwhelming. However, with the right guidance, this dog can become a devoted companion. The average life span for a male is 10–12 years, and the breed originates from Russia and other European countries. Bred to guard and herd livestock, the Caucasian Shepherd is strong and confident. Their size allows them to handle these tasks easily, but without proper training and socialization, they can become unpredictable and challenging.
