Sounds like it went well! And keep in mind, the handler can always request from the judge that they show the bite. I have never found a judge that refused that request.
I never request… I just put my hands on the mouth and lift the lips before the judge asks... no one has ever said a word to me about it.
Usually they just thank me for being so efficient! It is something that will settle him down if you are working with him on a table and checking his bite daily... then he knows you will do it and it won't bother him.
Also let others check his teeth and give him a treat... makes it all fun for them!
