Someone one on NeuroTalk pointed you out to me. I have MS and have had my service dog, Monty, a black Lab, for over four years. I live in Southwestern Virginia, 15 miles from Saint Francis Service Dogs, the organization that trained Monty.
I don't know where you live, but I can give you two websites to check out:
ADIonline.org They have a list of each state with all service dog organizations in each state.
Best of luck with your search. I wish you full and speedy recovery.
If you have any questions, I will be happy to try to answer them. Or, if you just need to "talk", please feel free to message me.
