Groom the air
While the game will show an error message if you try to feed a horse that's not in the stall, it fails to do so for grooming or petting the horse. You can send it out to the pasture and then do the grooming - the hitboxes for mane / tail and coat will still be where the horse usually stands. You can also increase your horse's trust by petting the wall behind where the horse should be. This doesn't gain you anything apart from a little chuckle.
