I've just been going through this with Rambo, only with him it was ALL judges -this is why I have been absent from the shows. Still don't know what happened to scare him. I tried all the tricks I was told about -rescue remedy, sereneum, different versions of scullcap & valerian etc etc -all that did was turn him really aggressive towards other dogs as he got TOO cocky. (That stopped as soon as he came off it!) We had the same problem, I could have 5 people go over him OUTSIDE the ring and he was fine, even with total strangers, then when inside the ring he'd freak out. He's getting a lot better now. Basically what has helped was to a) rest him and forget shows for a while, just do obedience b) keep getting people to go over him and TELL them about his problem c) setting up mock rings at ringcraft with tape so that it LOOKED more like an actual show d) gently grabbing his collar BEFORE anyone touched him, and keep stroking his back -that way he hasn't had a chance to back off as he's restrained, and with stroking him he doesn't know WHO is touching him -us or the judge, e) avoid like the plague any judges not on the BSDA lists and some of them as well! f) and what I think has made the biggest difference- getting him really worked up and happy by playing with him just before he goes in the ring so he's in a good mood -and playing in the ring too.
We had a couple of months break then tried a show, which happened to be Crufts -was not perfect but better. Break for another month then a show -and he was fine, even got placed first. Another month's break and another show and he was fine -all women judges so far to play safe. Now not doing anything until Working & Pastoral in July -this way his most recent memories of shows have been good ones.
Good luck!
