How do you motivate a pony with r+ if they have grass and don't really care about food anymore?
Idk what your situation is specifically but my horses are both on pasture and have 24/7 access to a round bale, and they still come in for training.
I mean like piece of advice #1 is, take them out of their grassy area and put them in a place where there is no grass, and train there. #2 Find a higher value food reward, like sweet feed.
But most of all, horses that are trained with positive reinforcement usually find the training itself super reinforcing, and it becomes less about the food (tho that doesn’t mean you can leave the food out altogether) and more about the fun of figuring out a puzzle.
Person 1 told Person 2 that when they were a kid, they always want a pony for Christmas, but they never did. So Person 2 goes on an adventure to try to get Person 1 a pony for Christmas, just for shits and giggles.
