I've discussed my previous fun times with Ebon and dog training before. My most recent project has been teaching him to carry his leash on walks. It's something I tried once before and failed, but I started over with slightly different tactics and we've made a fair amount of progress. If I coil the leash in a way that keeps him from dragging it he's rather happy to tote the thing around while we walk. I'm trying to make it clear that I want him to keep it in his mouth until I reach out to take it.
I still can't get him to sit without him spitting it out, though.
During training sessions, I have to use two leashes because of local ordinance. One goes in his mouth and the other is looped around my torso.
