Game bred dogs

Well, I'm just a newbie to these dogs but I am going to give my 2 cents... Way Out, you are right about there being some sort of sign most of the time. That however is not the case all the time. I have had Bulldogs that were multi time winners that were calm and collected around other dogs and wouldn't show the slightest sign of aggression towards them unless you stepped over them or put them in a box then it was a different story. I had a 32 lb female that would scream her head off digging and screaming to get to another dog in the box but she would let another dog run up to her and she would play with it until you dropped her collar. I had a male that was similar to her as well. I had a male that was a 2Xer that I caught hogs with and he wouldn't touch another dog in my he woods. No matter what I have never been one to allow any of my Bulldogs to run loose with any other dogs... PERIOD!! The rule I live by with these dogs and the dog aggression issue is "it's not if, it's when and how bad is it going to be when it happens". I don't allow my kids to be alone with any dogs, regardless of breed. The way I see it is if the dog has teeth it can and will bite given the right circumstances. I have raised my kids around these dogs and I have never worried about one of them biting them but I also never put them in that situation. The advice given above is as good as it gets... Get a catchdog from a catchdog line of that is what you are wanting to use it for. Gamedogs were/are bred for a purpose and that goes back a long time...
