I'm having trouble teaching my sister's bull terrier to lie down. I tried luring her into a down, didn't work, I tried moving the treat towards her side to get her to lie down, didn't work. I'm trying to have her crawl under my leg into a down but I don't know how to go from there or if there is another way to teach it. I think free shaping would take a long time for her to connect the word and the action. She learned to sit pretty fast but it took a month to teach her to learn to shake a paw. She loves to play and loves food!!! She has other behaviour problems to but I post them later.
