Thanks-- The trainer we're waiting to go see posted a video of her new rescue learning it, and I stole her act! We'd only been working on it for 10 or 15 minutes before I took this video; I waited until I could capture Robin doing it without luring or prompting it. She's getting quicker and cleaner today.
River, however, is still a bratty attention hog.
