Napping: When a horse, runs to the back of a ride, runs or drags towards the exit of the school or arenas, plants feet when taken out on own and refuses to go foward etc. Or the horse stands still and refuses to move in reaction to a worrisome or unpleasant situation (NewRiderForum).
As long as I know have her, Bonnie was prone to napping. In the first few months of owning her, it wasn’t a huge issue. Then, in July, it started to affect our partnership as it became more and more frequent and was beginning to get dangerous.
