Catch dog teeth setting???

Thanks for the clarification. I have a dogoxpitxgh thats just over a year hes only been on half a dozen hogs in the last four months or so. I noticed the other day that one of his larger rear teeth had like a pocket in between it and the gum, almost like it was pulled out a bit. I examined his teeth because he chewed through his cable tie out, (must be why people use chain) so it could have been from that to. I aslo have a six month old AB and I want to start him out right and not F him up due to impatience. I was at a hog tournament weigh in today and there was a young pit with one tooth that popped out and the other ripped out the side of the gum, it had only been on three hogs ever the guy said. he also said the dog was done, which I guess is not true if they catch with a full bite.
