Michigan: Boy attacked by pit bull at convenience store

MICHIGAN -- Yesterday I watched a boy get his leg mauled by a pit bull by Cumberland farms (a chain of convenience stores) ... Im hopping he makes a qwik recovery but his leg was chewed up pretty bad .... the owner came and beat the dog til it let go .REALLY, WHY would anyone have a monster dog like that?.. and today I look out my front door and there is a guy on the phone holding a 20 foot leash letting his dog crap on my yard REALLY?..... what is with these jackasses with dogs ... there are so many idiots that give good dog owners a bad rep
