Down took Gina the longest, but she usually picks up on a new trick right away, she is usually used to show off how to do a trick in her classes. Crawl also took a week to get down but she uses it to get things she otherwise couldn't reach. If you don't have one I strongly suggest a target stick, Amazon has one with a built in clicker, and it extends, for $19.99, I have 2 one on the coffee table and on that stays on her treat pouch.
Cheers Quad & Gina
