BlockBuster, I have had this happen to me a couple times when I use to use bullsnaps, and it never ended good. Yard accidents suck because you never really know what happened. I had a 9 month old pup that got hit by a grown male, and when I got home they were rockin' & rollin'. After I got them apart the pup wanted nothing to do with that grown male, but during the accident he was giving him the business. I just held on to him until he was old enough to check, and I ended up with the same results.
I also had a grown bitch get loose by pulling her angle iron out of the ground when it became soggy. I use to weld my chains to 2' foot long sticks of angle iron, but realized then it wasn't long enough. When I came home I found her in the dog house with a 6 month old puppy. They were both jacked up real bad, and the chains were tangled so tight that they looked like one dog with two heads. I got them loose and the grown bitch was trying to get ahold of every other dog on the yard, and the puppy didn't want to do shit. I took the grown bitch right to the barn and learned for the second time that she wasn't a finisher, but she wasn't a cur neither. I let the puppy grow up and just hoped for the best, but he turned out to be a cur. He never acted the same after that attack. He was a very hot and active little pup until the bitch got ahold of him, and after that he was a little shy and cautious around other dogs. I think he remembered that beating well. It was my own damn fault for having my animals on those snaps. I gave the bitch away to some gentlemen who were happy with her, I had no desire to breed her after that, nor did I plan on showing her.
