I would love to see the legislation for that. Let's outlaw a dog that may or may not be between thirty and eighty pounds, have drop or prick ears, a short or long muzzle, no specific pattern, be smooth or rough-coated, tall and slim or short and thick, any color including blue, red, brown, black, white, fawn, speckled, spotted, or any combination thereof.
Sound like any dog you know?
Then just declare open season on anything that even resembles a pit.
