BTW, I would love to do Pet Partners, but due to feeding a dehydrated Raw food, I can't. After the first two years with a very, very sick little dog, his current diet has cured nearly all his symptoms. So, I'm not really willing to compromise that either...
  
 what does that diet have to do with his ability to go with Pet Partners? 
Cali went through her CGC in a harness and no one, even the evaluator, said anything a out it.  One way around the AKC collar issues is to use a good fitting martingale  - course I had to make my own because no one made one small enough.  Several of the a therapy Dog training groups allow harnesses.
