I think its wonderful you can train your dog to get your medicine for you!!
Sorry you had to explain to some. I know our disabilities can really be imbarrassing at times. Never feel bad about having them, they are things we certainly didn't ask for. I think your dealing with it great!
I also have a disability, which I won't mention either. I take medication daily, and go to a forum where others have the same problem for support.
I wish I could come up with a way to teach mine to be service to me, as I'd love to have them fly free (since they are considered as 1 of our "carry ons anyway). I'd love to start flying when I go to see my Mom, but can't afford both of us a ticket!
When I travel in a car, I put Adonis in his Sherba carry on, and nobody has said anything to me. It has a shoulder strap, and is soft sided, and breathable, and you can barely tell there is a dog in it. Not leaving my dog in the car, as I live in the deep south, and summers are really hot here.
Not real sure but I'd bet the laws for service dogs are different in every state!
Wtg though on training to fetch meds! Thats COOL.
