This isn't my horse, but it made me wonder.
My friend has a 26 yo Quarter horse. He's had a few owners, but she's had him for four years.
She rides western and english, his bit is always a full cheek snaffle.
If she puts him in a loose ring, or anything else, he will not listen. At all.
The point of a full cheek/D ring is so that they feel the pressure on their face and move away from it, correct?
My mare does fine in all three, why won't he listen? Just because he's used to it?
