The Caucasian Mountain Dog has a keen sense of hearing and is quick to alert to strange sounds. This means that the breed is often noisy and barks a lot, especially at night. These traits must be carefully considered by the potential owner. Because the Caucasian Mountain Dog has functioned as a livestock guardian and a predator animal, he will protect the yard from a wolf, a coyote, a mountain lion, and the neighbor's dog. The properly socialized and trained Caucasian Mountain Dog is gentle and loving with his family. He is good with children and the family cat and is so loyal that he will sacrifice himself to protect his family. The Caucasian is sweet and charming--downright beguiling most of the time!
