Hello, I have a two year old Staffy cross who I am beginning to teach a complex skill. I am using a clicker as the conditioned reinforcer. The trick in mind is for her to take a tissue from a tissue box, bring it to me. I use the tissue and crumple it and thrown it on the ground. She then picks it up and puts it in a waste basket. However, I cannot get my head around forward/backward chaining and what part i should be teaching first and how i would chain them together? Would love some ideas on how I should approach. She has started sniffing the tissue (which i click and reward) and that's the stage she is at. Thanks!
