I switched to a 12' board (it's actually my teeter plank) because the 8' just wasn't cutting it.
I decided to go back to trying a toy with mixed results. He started looking back at me the more we did it. I think there were 2 that he missed, one of which I rewarded. I did way too many reps with him (more than even on this video, I got tired of editing). I didn't realize until I looked at the video.
