An unsocialized dog is like a sociopath. There really is no training them. That said, most people aren’t up to the task of responsible dog ownership. Especially true of unaltered dogs. The most you can expect of them is thst they keep their dogs confined.
That's not entirely true. The wife and watch the Animal Planet channel often. There is show of a group who rescue Pit Bulls trained and abused for dog fights. Once the Pits are taken out of that environment and shown love and affection and proper treatment, we're amazed to see them turn into loving well-behaved pets. It happens time and again. Check it out if you get the channel. And that's just one rescue group.
