The Caucasian Shepherd Dog is a strong-willed, loyal, fearless dog. This dog will fiercely protect whoever he believes is his family (including children, other dogs, and even cats) but will attack everyone else including friends of your children who may come to visit and play. The Caucasian Shepherd is not a breed for first-time owners. It is for experienced dog owners only who can dedicate a lot of time to train and socialize this majestic breed. Also known as the Caucasian Mountain Dog, he is a happy dog when he has a job to carry out and when he is used in what he is naturally born to do ie. guard and protect. The Caucasian Shepherd is not recommended for apartment life. They need space and will do best with at least a large yard.
