One of Antonio Pierce's hobbies on the Giants official website is breeding pit bulls. But according to Pierce, his interest in pit bulls is limited to an appreciation of the animals, not an exploitation of them. "Anybody who fights pit bulls is a punk," the middle linebacker said yesterday after the team's organized team activities workout at Giants Stadium. "It gives my dogs a bad rap. Everybody loves my dogs because they're good dogs. So of course I'm not pleased with it." Pierce refused to comment specifically on Vick, who has said he was unaware of the activities taking place on the property Vick owned in Virginia. But Pierce said he's been following the case and said, "None of it sounds positive. If (the evidence proves Vick was involved), then (prosecutors and the NFL) need to do what they need to do." Pierce said he owns four pit bulls and has sold several to his teammates and friends. But he said he has never sold one unless he was certain the dog wouldn't be involved in any kind of illegal activity. "Mine are all for show, for looks. They're all good-looking dogs and they're registered," Pierce said. "I only sell them to people I know. There's no Web site called antoniopiercepitbulls.com. "If I don't know you, you don't get one of my dogs."
