What is the difference between an english bridle and bit and an american bridle with bit?
Western bridle: used for American-style western riding, this bridle usually does not have a noseband. Many western bridles also lack browbands, sometimes replaced by a “one ear” (variations called “split ear,” “shaped ear,” and “slip ear”) design where a small strap encircles one or both ears to provide extra security to keep the bridle on. Some horse show styles do not have a throatlatch, most working styles do. Snaffle bridle: the “English-type” snaffle bridle is most commonly seen in English riding. It is a basic bridle that carries one bit and usually has one set of reins. Despite the name, a snaffle bridle may be used not only with a snaffle bit, but also with almost other types of single rein bits, including kimberwickes, gag bits, and single curb bits. The English bridle is almost always used with some type of cavesson noseband.
