Guard dog
Personal protection dogs are highly trained dogs who protect individuals or families against any threats. Personal protection dogs are trained to go anywhere with their owners and in many different situations. At home a guard dog may keep trespassers from entering. They have better hearing than humans and are usually aware of what is happening sooner. They act as a kind of home alarm. A dog's bark lets the owner know someone is there and alerts the trespasser the dog knows he is there. A guard dog can also provide protection should the intruder keep coming. Larger dogs make for better personal protection dogs. Some of the favorite breeds are German Shepherds, Boxers and Akitas. They are very trainable and look very intimidating to strangers.
