A bitting rig or bitting harness is a training tool for horses that can teach a horse to accept a bridle and bit, and later assist a horse in developing the necessary musculature for a given equestrianism discipline. Generally used in conjunction with training on a longe line, it is most often seen in the training of Saddle seat horses, but also is used by some dressage trainers and as a tool to start horses in driving.
A basic bitting rig consists of a surcingle (also known as a roller) that has a number of rings on either side, placed at varying heights, usually with a crupper to prevent the surcingle from sliding forward. A bridle is also part of a bitting rig, with side reins and rings or small pulleys on either side of the browband to accommodate an overcheck. Some variations use pulleys and leverage on side reins to create a given "headset." Other designs add straps resembling breeching on the hindquarters to encourage engagement of the horse's rear end.
The use of only a surcingle and side reins, a common component in basic horse training across all equestrian disciplines, is not usually considered a "bitting rig." It is the use of additional reins such as the overcheck, or the use of leverage to place the horse's head in a set position that turns a classic surcingle into a bitting rig.
Both a bitting rig and a classic surcingle with side reins are intended only to be used while longeing a horse. They are not to be used on a horse that is standing in a stall (though this is a very common type of misuse), nor are they used while riding. However, the surcingle and side reins are used as safety tools in the sport of equestrian vaulting.
While a surcingle and side reins are considered classical training tools, the use of the full bitting rig is controversial in some circles. The basic debate is whether the use of the overcheck or any other rein setup other than the classic side rein is unnatural and develops incorrect musculature in the neck, back, and hindquarters. Like any tool, a bitting rig can be overused, leading to soreness and fatigue in the horse, and in some cases, improper use may teach a horse to lean on the bit and develop a hard mouth rather than relaxing and giving to it. Misuse can also lead to a horse that holds its head in a set position, but fails to properly engage the hindquarters and learn proper collection. Proponents argue that it safely teaches a horse a correct head position and gently accustoms a horse to what will be expected of it when carrying a rider.
Tack is equipment or accessories equipped on horses and other equines in the course of their use as domesticated animals. Saddles, stirrups, bridles, halters, reins, bits, harnesses, martingales, and breastplates are all forms of horse tack. Equipping a horse is often referred to as tacking up. A room to store such equipment, usually near or in a stable, is a tack room.
A bridle is a piece of equipment used to direct a horse. As defined in the Oxford English Dictionary, the "bridle" includes both the headstall that holds a bit that goes in the mouth of a horse, and the reins that are attached to the bit.
Longeing or lungeing is a technique for training and exercising horses. It is also a critical component of the sport of equestrian vaulting.
A surcingle is a strap made of leather or leather-like synthetic materials such as nylon or neoprene, sometimes with elastic, that fastens around the horse's girth.
A noseband is the part of a horse's bridle that encircles the nose and jaw of the horse. In English riding, where the noseband is separately attached to its own headstall or crownpiece, held independently of the bit, it is often called a cavesson or caveson noseband. In other styles of riding, a simple noseband is sometimes attached directly to the same headstall as the bit.
A pelham bit is a type of bit used when riding a horse. It has elements of both a curb bit and a snaffle bit. In this respect a pelham bit functions similar to a double bridle, and like a double bridle it normally has "double" reins: a set of curb reins and a set of snaffle reins. Because it has a bit shank and can exert curb-style pressure on the horse, it is considered a curb bit. Like all curb bits, a pelham bit has a mouthpiece, shanks with both purchase and lever arms, a ring for rein attachment at the bottom of the shank, and a curb chain. But like a snaffle bit, a pelham bit also has a bit ring on either side of the mouthpiece. Like some curb bits, a pelham bit usually has "loose" shanks - hinged at the mouthpiece in the same way that the rings of a snaffle bit are hinged. When two sets of reins are used, the snaffle rein generally is wider, to help distinguish it from the curb. A "cowboy pelham" is a western style of loose-jawed curb bit with additional rings at the mouthpiece allowing a second set of reins to be added.
A double bridle, also called a full bridle or Weymouth bridle, is a bridle that has two bits and four reins. One bit is the bradoon, is a modified snaffle bit that is smaller in diameter and has smaller bit rings than a traditional snaffle, and it is adjusted so that it sits above and behind the other bit, a curb bit. Another term for this combination of curb and snaffle bit is a "bit and bradoon", where the word "bit" in this particular context refers to the curb.
Side reins are equipment used when longeing a horse, running from the bit of the bridle to the saddle or surcingle. As a horse training tool, they encourage flexion and softness in the horse's mouth. For longe line work with a rider up who does not carry ordinary riding reins, they help calm and settle the animal. However, they are a tool best used by experienced handlers; used improperly they may unduly restrict the horse's movement or cause an accident.
A martingale is any of several designs of tack that are used on horses to control head carriage. Martingales may be seen in a wide variety of equestrian disciplines, both riding and driving. Rules for their use vary widely; in some disciplines they are never used, others allow them for schooling but not in judged performance, and some organizations allow certain designs in competition.
A chambon is a piece of horse tack. It is a strap that runs forward from the bottom of the girth or surcingle, and forks. The forks continue to a ring on either side of the bridle or halter, at the base of the crownpiece. Running through those rings, the forks follow the cheekpieces to the bit. They may attach to the bit or pass through the bit rings and attach to themselves below the horse's neck.
Reins are items of horse tack, used to direct a horse or other animal used for riding. They are long straps that can be made of leather, nylon, metal, or other materials, and attach to a bridle via either its bit or its noseband.
Horse training refers to a variety of practices that teach horses to perform certain behaviors when commanded to do so by humans. Horses are trained to be manageable by humans for everyday care as well as for equestrian activities from horse racing to therapeutic horseback riding for people with disabilities.
A hackamore is a type of animal headgear which does not have a bit. Instead, it has a special type of noseband that works on pressure points on the face, nose, and chin. It is most commonly associated with certain styles of riding horses.
The bit shank is the side piece or cheekpiece of a curb bit, part of the bridle, used when riding on horses. The bit shank allows leverage to be added to the pressure of the rider's hands on the bit. Shanks are usually made of metal, may be straight or curved, and may be decorated in some disciplines. The headstall and curb chain or curb strap of the bridle is attached to the top of the shank, and the reins are attached at the bottom. Shanked curb bits are used in western riding for nearly all adult horses, and are seen in English riding disciplines primarily as part of the double bridle used by advanced dressage riders, and on the hybrid pelham bit that includes a ring for a second rein attached at the bit mouthpiece.
A bearing rein, known today as an overcheck or a checkrein, is a piece of horse tack that runs from a point on the horse's back, over the head, to a bit. It is used to prevent the horse from lowering its head beyond a fixed point. A variation called a side check passes beside the ears through loops at the top of the bridle cheekpieces.
Draw reins and running reins are pieces of riding equipment used for training that use the mechanical advantage of a 'single movable pulley' to cause the horse to bring its head down and inward. While a regular rein is the strap that attaches to the bit and is held by the rider, these types of reins slide through the bit ring, adding leverage to the rider's hands and arms, allowing the rider to force the horse's head into a desired position.
The Gogue is a piece of horse tack used for training purposes, and is very popular in Europe, with a similar place in training regimes as side reins. Its purpose is to encourage the horse to raise the neck, free the shoulders and engage the hocks, so that he may develop the correct muscles for a rounded topline.
Riding aids are the cues a rider gives to a horse to communicate what they want the animal to do. Riding aids are broken into the natural aids and the artificial aids.
The bit is an important item of a horse's tack. It usually refers to the assembly of components that contacts and controls the horses mouth, and includes the shanks, rings, cheekpads and mullen, all described here below, but it also sometimes simply refers to the mullen, the piece that fits inside the horses mouth. The mullen extends across the horses mouth and rests on the bars, the region between the incisors and molars where there are no teeth. The bit is located on the horse's head by the headstall, and which has itself several components to allow the most comfortable adjustment of bit location and control.
A bitless bridle is a general term describing a wide range of headgear for horses or other animals that controls the animal without using a bit. Direction control may also be via a noseband or cavesson, if one is used. The term hackamore is the most historically accurate word for most common forms of bitless headgear. However, some modern bitless designs of horse headgear lack the heavy noseband of a true hackamore and instead use straps that tighten around a horse's head to apply pressure in various ways. These are often specifically patented and marketed as "bitless bridles", usually referencing a particular type of headgear known as the cross-under, though other designs are sometimes also given similar names.
