1. Shepherd in Caucasian

A huge breed that can weigh up to 200 pounds is the Caucasian Shepherd, also referred to as the Caucasian Ovcharka. That weight alone can be challenging for someone who is unfamiliar with such massive beasts. However, with the right training, this dog might develop into a wonderful friend. The average lifespan of a male adult is 10–12 years, and this breed has roots in Russia and other European nations. The Caucasian Shepherd is a strong, self-assured canine that was initially bred for herding and protecting cattle. Due to their size, the breed can easily perform these tasks. However, if they are not properly trained and socialized, it may contribute to their being aggressive and dangerous.
