Agree with Lisa and msvette2u.
You need two to show - judge checks that along with teeth, etc. If you artificially make the other one descend in order to show, that is ok if you are only doing it for fun - however, if I am going to get nitpicky, this is technically cheating. You have surgically altered your non-show worthy dog in order to show and get a show rating. This dog should *NOT* be bred. He has a genetic fault. Surgically altering that for health and a prerequisite to show for fun is ok, but again, this is NOT a breed worthy dog - sorry. If you had a clause for this in your contract, you may be owed compensation. Otherwise, just enjoy the dog.
