I wouldnt want to be patted on the head either LOL! Petted might be ok.

You probably could change her reaction by you and others giving her treats and praise when petting on the head but i would only let people you trust to do it nicely do it. The tester is going to pet her nicely on the head.. not fast ,grabby or hard. I had the same problem with feet on Hoolie but he improved with interaction with responsible people. Good luck.. i didnt think Hoolie would pass the test but he did quite nicely

I have just started training the new puppy to get her to a point where i can put her in a CGC class.
