I recently attended a show where I helped a fellow exhibitor handle in the challenge line up because they had 2 dogs in for challenge. I have just seen this same exhibitor is judging in a couple of months and I would like to enter. Can someone tell me if this is ok under NSW rules and regulations? I've tried to look on Dogs NSW website, but can't find any info on it. If anyone can help it would be very much appreciated. thank you
