Have any of you ridden/owned horses with vices? How did it affect you/your horse during riding?
One of the horses I ride is a really terrible windsucker, so bad that his teeth are practically little nubs and if he lifts his head while drinking water is just falls right out of his mouth

it doesnt really affect him so much when we are riding but he is a huge pain to bridle because he'll be totally focused on his cribbing. Unfortunately, because he isn't my horse, there isn't much I can do to help him
