We’re progressing with Zen training even though I have not managed to do a solid training session every day. We do at least a bit every day, though. We’ve probably used another 300 treats or so out of our 1,000.
How I’ve been starting it is when my PCA brings me a meal, I usually still need to cue Zen (either “Leave It” if I’m verbal or “Eh!” if I’m not) and then after one or maybe two cues, we move to the food and my eating being the cue.
Barnum will now look up with anticipation for a training session when he hears me chewing. This would seem to be counterproductive, and I admit that I feel on the knife edge of creating a behavior chain, so I’m trying to head that off at the pass. I can pretty quickly now get him from sniffing at me or the food to backing up and ending up on his mat across the room.
I’ve reduced the number of repetitions — lowered rate of reinforcement in going for longer durations — and this means that sometimes he gets up from the mat and comes over. I’ve decided that if he wants to get on the bed to look out the window while I’m eating, that’s fine. Anything that maintains “ignoring food” as the goal behavior is OK. But if he comes back on the bed, looks out the window for a while, and then sniffs my food, he gets (as Sue Ailsby puts it), The Big Prize! Which is that he gets to go and lie in his crate for a couple of minutes and then be released. (No treat.)
Here are some pictures from a session a three days ago. This was after we had taken a break from formal sessions for a few days.

While not actually relaxed, Barnum is offering a more relaxed pose (and he sighed after putting his head down, earning a click).
Peace,

P.S. I’m keeping my blogging to a minimum and trying to do less typing in general, including alt tags for the pictures, because I’m having repetitive strain issues with my hands. That’s scary because I spend all my time on the computer!
