I'd say shame on your instructor for thinking any kind of teeth bite that leaves a bruise is acceptable!
You know, the more I'm with her, the more I'm not liking her. I mean, she's super nice, and that is what attracted me to her in the first place. But she's so nice, to where we don't get anything done in my lessons. So, I'm paying 40/hr for MAYBE 30 mins of riding, and she doesn't push me, which on one hand I'm thankful for, because some times I don't feel comfortable, but on the other hand, it DOES get boring just sitting on the horse, going around the arena. Anyway, back to topic.
Yea, she said it was fine.. I was more worried about it, the biting, becoming more of a habit. He's to big a horse to have bad habits.
Sonny used to do that...no bits just fool around with my skin with his lip...as if he was grooming me. He didn't do anything with his teeth. That's a love "nip" as I call it, and it isn't bad. Horses do it all the time to each other.
