Buy a few pitbulls... Make sure they are red nose nasty pits.... Train them in German..... SCHNELL!!!!!
sorry, but no, that's an idiotic idea. besides the fact that any sort of violence in this situation is going to cause nothing but more violence, as in i would imagine the 2 guys that the 2 friends brought over, have friends of their own who would want payback, i personally can't stand someone who would do that to any kind of dog. if you trained a dog to attack someone, and then it did, if someone saw it and reported it, the dog would be taken and then put to sleep and destroyed. plus, pitbulls already have enough of a bad name for their breed that isn't deserved, they don't need some stupid jerkoff making them attack dogs and make the whole thing worse.
