So I am curious what service dogs in training can do. I.E: can they go in stores, etc.? Basically, what's the difference between a service dog in training and a service dog ( besides being in training)? In about 6 weeks I am getting a puppy that I am hoping to train as my service dog. (Please no flack about owner trained service dogs, I know what I am doing and have a trainer to help.) But I don't quite understand what a "service dog in training" is.
