We completed Cooper's basic manners training by working on an "automatic" Leave It. This is more of an advanced skill, but Cooper only takes things off the desk when someone leaves the room so a regular Leave It doesn't work as well. We tempted him with remote controls, socks, flip flops, even cat food, and he did pretty well. It will still take some work because he has been reinforced by taking them in the past, but this was a great start.
