Here is a thread that might be helpful.

Since that thread, I have noticed a lot of Facebook "Groups" that have started up about having, training and being partnered with Service Dogs. Most are good resources for connecting with other service dog users and learning about what is involved.
There are a couple other threads about service dogs here on the RSD forum that you can search for... and if you go to the Pets Forum here on NeuroTalk, there is a sub-forum in it for Service Animals.
Hope that helps.
My hands have become much worse since the post I linked to above, and it has become much harder for me to type, so I seldom post to the forums now. I used to be able to type long posts or private messages to answer questions but right now that is very hard. But the links in the post and the Facebook groups are very helpful. Some of the people in the FB groups have RSD, and can speak to what the dogs do to help them.
