Kota and Tanner both seem to have "take" down. Now I'm working on figuring how to shape it into a Hold. They will gladly hold the rope bone, but I'd also like to incorporate having them "take" other objects. Kota was easier to train than I thought because normally he doesn't want anything in his mouth.
You will notice in the video that Kota is more interested in my hotdog smelling finger than the bone at first. Food works great with him because it's all about how it smells. I hid the hotdog behind the bone the first couple of times because he could smell it making him more willing to put it in his mouth, maybe he was hoping the rope bone was made of hotdog.
