We have all heard
"You can lead a horse to water, but you can't make them drink", but can you teach a horse to crap every time in a designated spot in their stall?
If so How?
Top Groom class 101
First clean the stall real good.
Add fresh bedding.
Take a pile of fresh crap from a different horse (preferable from the opposite sex) and put it where ever you want your horse to crap. Your horse will walk in smell the fresh crap turn around and crap on top of it.
Do this for a few days and most horses will crap in that same spot for years to come.
