I let my sim's daughter try out the family horse and it is cute the horses bend down like that to help them.

He didn't even try to buck her off like he sometimes does to her father, canceling the ride after telling him to bring her home may have caused an issue.

They got back he went to the bathroom, fine, but he still wasn't sleeping in his bed so I let her mom try and she was reset off, then her husband was. I took him into cas and changed his outfit and he was fixed, if that happens to anyone else with a family horse.
