I would have to agree with those that have stated that the bigger dogs get a bad rap because their bites by nature do more harm. It is also the problem of the culture that thinks it is cool to have an aggressive dog and don't know or care how to train it. Then you have a large potentially dangerous dog with no socialization skills that can cause serious harm. I agree that if a dog attacks a human it should be put down. But there is a big difference between an attack and a bite. Many dogs, labs and poodles included, will snap at you if you hurt them, even on accident. This does not make the dog "aggressive". It makes it an animal. I also think that the circumstances should be taken into account in a biting case. Did the person enter the dogs territory uninvited by the owner? Were they tormenting the dog? I think a one bite and put it down law would be a mistake.
