The Caucasian Ovcharka is a member of the extremely large, very willful, and demonically intelligent tree of the dog family. This doggo decided silly kid shouldn't be allowed to play in the ocean without a life jacket. Canine Overlord immediately corrects the situation.
A CO is a bad choice for anyone who isn't an experienced large breed dog owner. They are guard dogs first and cuddly mountains of fur second. There is no known maximum size, they are fearless and extremely aggressive when the guard genes kick in.
