Would something like that open quick enough? My boss has a Bull Mastiff. He's geting a little older, but he still weighs in around 160lbs. My boss can use his collar as a belt. As for someone saying a dog would attack a kid instead, that's why you train them. Like the police do, pick words from a foreign language or something like that. Maybe the police have it right. Get a shot gun, a hand gun, a dog, some pepper spray, a beater stick AND some backup!
