One of my dogs used to stand fore square when showing now is just fidgets and also used to look at me when I used to say "Watch Me" now he looks anywhere but towards me even if I have a food never had this problems with any of my dogs before nor with the other one I have now. Why?

Just a training thing :) hard to exactly where it's broken down with limited info.

Perhaps he's just bored with the show scene - it might be a good time to keep up with the ringcraft, but rest him off shows for a while.  Showing is expensive and if he's chucking his chances by misbehaving, why push it!!   Your decision.

I had same issue with one of my heavys horses inhand best thing is give your dog rest few months off will do.him/her good but again its your dog you no him/ her best
good luck

We only do champ shows and not all of them and possible 1 or 2 opens shows a year.

We did have a rest for 3 months and thought that would help, but no, he shows perfectly if in a field or training. I thought of getting someone else to show him but no one interested.

He is probably picking up on your anxiety. Try to make it as much fun for him as possible
