you may think a dog needs to be trained to kill. However, train a 40 pound lab to kill then train an 80 pound pit to kill. One obviously takes to it better than the other, but I won't dare say which one. On the other hand train each of the two breeds to be well manored. Which breed is most likely to deviate and make a fatal mistake, and if both breeds go nuts which one is more likely to do more damage. Again, I won't say but the answer is obvious. go labs go. And if you have a pit, love him as much as he loves you and be aware of peoples fear of him, and create a barrier because you love him not to suppress him.
