You see a guy walking a pit bull with a studded __1__. What's your first thought: tough guy, right? Well, probably. But chances are he's a conscientious, rule-abiding tough guy. So says a study in the journal Anthrozoos.?

Researchers gave personality tests to 235 subjects—from teens to people in their 60s. Those subjects also rated how aggressive they considered different __2__ of dogs to be, from Cocker Spaniels to Pit Bulls, and chose which type they'd most like to own.

As the authors expected, the most unfriendly study volunteers, and the youngest, preferred the meanest breeds. But the __3__ ends there. Pit bull lovers weren't any more likely to have delinquent past behavior—like carrying weapons for fights—than people who preferred friendly Labs.

In fact, pit bull lovers actually scored higher for __4__ on the personality test. Which means they may be more rule-oriented, careful and organized—the perfect candidates for dog training classes, the authors say. So next time you see someone walking a __5__ dog, that person’s bark may be worse than his bite.?
