my boss used to show and breed chow's and she said that it doesn't matter what the judge does, they get poked, probed and touched all over and they can not under any circumstances appear annoyed at the handling or try to bit. no offense or anything but you shouldn't be making excuses for this behavior (heat, poked too ahrd ect.) i'm not sure about there but over here if the dog bites they aren't given many chances and then that dog is eventually banned from showing. and even just lunging at the judge while in line makes the judge think twice about selecting him as a winner.
