I haven't been on much due to computer problems both at home and work so I just saw this. I have to say it looks worse now than when you first found it. When Jasmine was born and I was in Texas with her and Christy, we found a puncture wound on Dakota's side. We couldn't figure out what it had come from either. We took her to the vet and he said we needed to walk around the yard and look for something about that high. He thought it might have come from the fence. I thought he was crazy but we went home and sure enough there was a wire that was sticking out of the fence right at the heighth. The way she and the other dogs run I imagine she got pushed right into it. I hope Bon continues to heal and that ugly thing becomes a small scar all covered over by his hair.
