Panda is a miniature horse with an unusual job. She's a guide for her blind owner. We’ve been talking a lot about cues in the recent podcasts. I can think of no better way to illustrate the concepts we’ve been exploring than to talk about Panda’s training and the job she does for her owner, Ann Edie. This is part one of our conversation with Ann. We begin with some history and the contrast between commands and cues.
