Not true, most viloent breed of dogs depend on the breed. I was doing my paper round earlier, and when i pushed a paper through this door, the dog jumped up madly (i think it was a germa shepard) and bit the paper from out of the letter box. I think that if the door wasnt there, then i would have been seriously injured. Certain breeds have the potential to be meaner. Like, a Chihuahua isn't going to eat your face off, but a Pitbull would. But it still depends on how they're raised. You should have to have a permit to own ANY large-breed dog in my opinion, and the people giving out permits should heavily use stereotyping when issuing them. The people will the violent dogs are always the same...They look like hicks. Being buying Pitbull's aren't helping them. Most people are buying them for the "cool" factor knowing that they CAN rip someone's face off. They're not being trained to do so, though. My sister's boyfriend bought one because he thought they were cool, and the dog turned out to be a big, moronic moose. :P I absolutely hate cichauhaus, a rabid one charged and bit my leg a couple months ago while walking my dog.
