ELI5: If you are completely blind, how do you get your guide-dog to take you where you want to go? How is that communicated?

It doesn't work like that. The guide dog does not lead the blind, it restrains them. The blind person goes where they want to go and the dog will pull back to avoid danger such as roads. If the blind person wants to go to the market or something they need to go themselves; the dog doesn't know where that is, there is no way to communicate it, and it isn't part of their training.
