Strikes me there's a lot of folks on this thread haven't the first idea about proper manstoppers (and yard dogs rarely are)they take a LOT of work,time,dedication and responsibility and believe me a dog thats tested to the full will take more pressure than most could imagine that said they are not bullet proof but realistically who is going tooled up to steal your cur from its kennel,if the dog does its job its more likely to catch hep c from the smack head it bites than get a bullet.
