The Caucasian Shepherd, or Caucasian Ovcharka, is a giant breed that can weigh up to 200 pounds. For those unfamiliar with large dogs, this size can be quite intimidating. However, with appropriate training, this breed can become a devoted companion. Males typically live for 10–12 years, and the breed originates from Russia and other European regions. Bred to protect and herd livestock, the Caucasian Shepherd is both strong and confident. Their size aids them in these roles, but without proper training and socialization, they may become aggressive and dangerous.
