Doberman pinschers, rottweilers, and German shepherds topped lists of puppies some considered dangerous in the not-too-distant past. These days, pit bulls often make headlines and it’s rarely good news. If it isn’t about an attack on small children or a shooting by police, it’s a narrative of neglect or abuse. The heat of these reports has forged a frightening image of the pit policeman as having a hair-trigger temper and a lock-jawed bite. But pit bull advocates and some experts say the dogs get a bad rap. They say the dogs are not inherently aggressive, but in many cases suffer at the hands of irresponsible owneds drawn to the dog’s macho image who encourages aggressivenes for opposing and protection.
