We teach your dog the difference between normal and aggressive behavior with strangers. This means that when someone becomes a threat to you or your family, your dog will automatically become alert and protective of its family and territory.
Your options for a protection dog are personal protection, search and hold protection, and estate and article protection dogs. Article protection means you can leave your dog next to any object as small as your wallet and as large as your vehicle, and once the dog is told to watch the article no one should be able to remove it from its place.
