It would be cool to have a 300 lb. attack wolf with a spiked collar, 5 rows of razor sharp teeth, and a bitter distaste for criminals to protect your home, but food could get expensive. If you're looking for an effective, affordable solution, the Rex Plus may be just what you need. Simply install this portable device right next to a door or window and it plays a simulation of an attack dog barking should anyone come within 30 ft. (adjustable). For less risky times of day, or when expecting guests, try the rainforest sounds alert. If you're in a joking mood, keep the dog barking for the guests you're expecting!
