With Pitts, I wouldn't say that he is lucky. It is all how they are raised really. They just get a bad rap because of how so many of them are abused and raised to be mean. Any dog raised in similar conditions that some of these Pitts are will be mean. Now, some breeds are what some may call one owner dogs, and a Pitt is definitely one of those breeds. They will attach to whomever they feel is the "alpha" of the "pack"/family. So, if the alpha is the women of the house, then the dog will be protective and guarded around her, and read off her body language. etc.
I've had Boarder Collies most of my life. I really appreciate an intelligent animal.
As far as being able to put down a feral dog. Before my folks and brother had moved out to the country, I would have agreed.
But now, seeing what feral dogs can do to terrorize livestock, yes, it is too expensive to not put them down. You also get a feel for who is your neighbours and your neighbours dogs. So you recognize them and they you, and you know that you might ought to have a talk with your neighbour before shooting their dog if they get out. Plus, you learn their habits. So it isn't like you are talking about someone's pet necessarily. As was pointed out, a lot of people will go out to the country to dump their no longer wanted, or affordable pet and hope it either figures out how to survive out in the wild or someone will pick it up. Usually what happens is they will mostly end up getting hit by a car, or shot when trying to go for an easy kill on someone's farm near their chicken coop. The ones that make it, which are very few, may come up with disease and other issues since dogs are so domesticated they are not used to the wild, and they will suffer and die, but worse yet, is they may spread diseases to the local farmers pets and live stock, which you really don't want to happen.
Anyway, I got way far afield there. I'll shut up now.
