How good is a Caucasian Shepherd for guarding?

The Caucasian Shepherd is a very strong, brave, and alert dog, excellent at guarding homes. Their combat ability is formidable and their alertness high, so they protect family and territory well.

Caucasian Shepherds are usually wary of strangers, with strong deterrence and a firm self-stance and a strong instinct to protect their owner. But their aggression is much stronger than other dogs, so the owner must give it some socialization training to prevent it from attacking people randomly.
