Yes, I have a service dog for CRPS. My dog provides me with mobility assistance (balance, counterbalance, brace), blocking and protecting my "right side", deep pressure therapy for the tremors, circling to protect me, wheelchair ambulation, medication and item retrieval, (I want to train "find help", along with guiding to exits, and carrying bagged items). I feel like there's more, but I'm forgetting. I'm very knowledgeable about SD'S and was just referred to this forum, and I'd love to help someone out who is looking :-)
