A different trainer is coming to our house on Saturday to do an assessment. She will do a temperament test and then hang around for an 1 1/2 or so and check him out. We discussed a few possibilities that I won't mention here because right now it's all guessing, but she did say that there are exercises we can do to correct the situation. Poor guy learned a lot of things that he's going to have to unlearn with us. I'll update this weekend.
