What are the best family guard dogs?

Bullmastiffs rank high as family guard dogs on many pet-related websites. Family Circle notes that these dogs are "softies on the inside" and good with children. Other breeds that receive frequent mention as good family guard dogs include German shepherds, Rottweilers, boxers and Komodors.

When choosing a family guard dog, the individual dog's traits are more important than the breed's traits. A good family guard dog combines an intimidating appearance and the physical ability to take down an intruder with a nature that is loyal and protective, but not overly aggressive. All guard dogs need proper socialization and training, and no dog should be left unsupervised with young children, particularly children he does not know.
