Tristan has a bit of a colic history. At some point, I got into the habit of praising him every time he poops. I usually say something like “Good job! Ponies who poop are my favorites!”
Yes, I get that that’s weird.
Anyway, last night he pooped when he got back into his stall, and I praised him, and then turned away to pick up his saddle to put it away.
I turned back, and there he was, begging for a treat.
I may have accidentally done some operant training here…
