See if you can get him near a wheelchair and what the reaction is. My neighbor was in an accident and we walked up to him while he was in the wheelchair, she was skitish but it was ok. I should have rented one for a week and left it in my livingroom. The day we took the test there was a man in a wheelchair recertifing his dog and the dog was "staring" at Lakota so Lakota gave a bark. The tester told me that was what happened and to take her outside for a while, and that she should not have allowed me to take the test. Lakota took the CGC cold, we hadn't been to classes for a few months and she passed by the hair on her butt. Mostly because she doesn't like when people pat the top of her head, she puts her ears down. When you practices long down stays, leave the room. I used to hide behind the door.
