If you're talking about a curb strap on a curb bit, then yes, it is required. If you are talking about a curb strap for a snaffle bit, then no, it is not required. Bosals do not require a curb strap. If you are talking about a chin strap for the western hat, no, one is not required. It is not required but I strongly recommend because with out it the bit has too much movement that may confuse the horse.
