Five bites...only one answer here...unpleasant as it is. No use asking if you did anything wrong, that's water under the bridge (but likely not, in a major way, anything you did). I suppose you could talk to the breeder, but they would likely do what you don't want to have to do, and then he would leave for the bridge with strangers...if you love him and want what's best for HIM, you're going to have to be very strong and do the right thing for him. DO NOT, under any circumstances re-home him via craigslist or over the internet, believe me when I tell you there are much worse things than a humane euth out there...sales for experimentation and bait for dog fighters...and this is exactly the kind of dog they're looking for. I'm so sorry, but I don't see any other safe solution.
