Simple horse twitch

A twitch is a device that is used to restrain horses during various stressful situations, such as veterinary treatment. [1] It is usually made up of a stick-like handle loop of chain or rope on the end, or a metal ring with a rope loop which is wrapped around the upper lip of the horse and tightened. Another design, sometimes called a "humane" twitch, is a plier-like clamp that squeezes the lip with motion akin to that seen in a nutcracker. The aluminium screw twitch is yet another form of twitch.

Use

The upper lip of the horse is grasped and the loop of chain or rope is placed around it, then the handle of the twitch is twisted until the loop is firmly around the lip. A wooden handled twitch has the disadvantage that it requires a handler and the handle may injure the horse handler if the horse throws its head. Other twitches may be attached to the halter or headcollar. An emergency twitch can be improvised by placing a loop of leather or heavy cord around the nose and tightening it by twisting a stick around and around until it is tightened sufficiently. [2]

The twitch is popularly believed to work by distracting the horse, but may act instead by triggering the release of endorphins from the horse's brain, producing a calming effect. [3] It is hypothesized that its effects are similar to acupuncture. [1] The twitch is considered a humane method of restraint and is commonly used by horsemen and veterinarians to keep an animal still and quiet. [2]

Misuses

A twitch is not intended to replace proper pain management of the horse. [1] It is not intended for use on any other part of the body of the horse other than the upper lip. It may cause permanent damage and behavioral issues if it is used--even correctly--such as a head-shy horse when used on the ear. Additionally, if a twitch is left on for an extended period of time, it can cause permanent damage. [1]

Tack is equipment or accessories equipped on horses and other equines in the course of their use as domesticated animals. This equipment includes such items as saddles, stirrups, bridles, halters, reins, bits, and harnesses. Equipping a horse is often referred to as tacking up, and involves putting the tack equipment on the horse. A room to store such equipment, usually near or in a stable, is a tack room.

The constrictor knot is one of the most effective binding knots. Simple and secure, it is a harsh knot that can be difficult or impossible to untie once tightened. It is made similarly to a clove hitch but with one end passed under the other, forming an overhand knot under a riding turn. The double constrictor knot is an even more robust variation that features two riding turns.

<span class="mw-page-title-main">Whip</span> Tool or weapon used to train animals either by sound or physical pain.

A whip is a tool or weapon designed to strike humans or animals to exert control through pain compliance or fear of pain. They can also be used without inflicting pain, for audiovisual cues, such as in equestrianism. They are generally either a firm stick designed for direct contact, or a flexible line requiring a specialized swing. The former is easier and more precise, the latter offers longer reach and greater force. A hunting whip combines a firm stick with a flexible line.

Bondage in BDSM, is the activity of tying or restraining people using equipment such as chains, cuffs, or collars for mutual erotic pleasure. According to the Kinsey Institute, 12% of females and 22% of males respond erotically to BDSM.

Animal euthanasia is the act of killing an animal humanely, most commonly with injectable drugs. Reasons for euthanasia include incurable conditions or diseases, lack of resources to continue supporting the animal, or laboratory test procedures. Euthanasia methods are designed to cause minimal pain and distress. Euthanasia is distinct from animal slaughter and pest control.

Livestock branding is a technique for marking livestock so as to identify the owner. Originally, livestock branding only referred to hot branding large stock with a branding iron, though the term now includes alternative techniques. Other forms of livestock identification include freeze branding, inner lip or ear tattoos, earmarking, ear tagging, and radio-frequency identification (RFID), which is tagging with a microchip implant. The semi-permanent paint markings used to identify sheep are called a paint or color brand. In the American West, branding evolved into a complex marking system still in use today.

<span class="mw-page-title-main">Bridle</span> Piece of equipment used to direct a horse

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. It provides additional control and communication through rein pressure.

<span class="mw-page-title-main">Halter</span> Animal headgear

A halter or headcollar is headgear that is used to lead or tie up livestock and, occasionally, other animals; it fits behind the ears, and around the muzzle. To handle the animal, usually a lead rope is attached. On smaller animals, such as dogs, a leash is attached to the halter.

A dog collar is a piece of material put around the neck of a dog. A collar may be used for restraint, identification, fashion, protection, or training. Identification tags and medical information are often placed on dog collars. Collars are often used in conjunction with a leash for restraining a dog. Collars can be traumatic to the trachea if the dog pulls against the restraint of the leash, causing severe pressure to the neck. Use of a harness instead of a collar may be beneficial for dogs prone to tracheitis or those with a collapsed trachea. Conversely, dog breeds with slender necks or smaller heads may easily slip out of collars that are too loose. This can be avoided by using a martingale dog collar which tightens to distribute pressure around the neck when training the dog not to pull. Any style of dog collar must be properly fitted to ensure safety and collars should not be worn when the dog is unattended.

<span class="mw-page-title-main">Natural horsemanship</span> Collective term for a variety of horse training techniques

Natural horsemanship is a collective term for a variety of horse training techniques which have seen rapid growth in popularity since the 1980s. The techniques vary in their precise tenets but generally share principles of "a kinder and gentler cowboy" to develop a rapport with horses, using methods said to be derived from observation of the natural behavior of free-roaming horses and rejecting abusive training methods.

<span class="mw-page-title-main">Hobble (device)</span>

A hobble, or spancel, is a device which prevents or limits the locomotion of an animal, by tethering one or more legs. Although hobbles are most commonly used on horses, they are also sometimes used on other animals. On dogs, they are used especially during force-fetch training to limit the movement of a dog's front paws when training it to stay still. They are made from leather, rope, or synthetic materials such as nylon or neoprene. There are various designs for breeding, casting, and mounting horses.

<span class="mw-page-title-main">Hackamore</span>

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. Hackamores are most often seen in western riding and other styles of riding derived from Spanish traditions, and are occasionally seen in some English riding disciplines such as show jumping and the stadium phase of eventing. Various hackamore designs are also popular for endurance riding. While usually used to start young horses, they are often seen on mature horses with dental issues that make bit use painful, and on horses with mouth or tongue injuries that would be aggravated by a bit. Some riders also like to use them in the winter to avoid putting a frozen metal bit into a horse's mouth. In the Mexican Charro tradition, the Jáquima and Bozal substituted for the serrated iron cavesson used in Spain for training horses.

<span class="mw-page-title-main">Chain</span> Series of connected links which are typically made of metal

A chain is a serial assembly of connected pieces, called links, typically made of metal, with an overall character similar to that of a rope in that it is flexible and curved in compression but linear, rigid, and load-bearing in tension. A chain may consist of two or more links. Chains can be classified by their design, which can be dictated by their use:

<span class="mw-page-title-main">Nose ring (animal)</span> For controlling bulls and weaning calves

A nose ring is inserted into the nose of an animal. Nose rings are used to control bulls and occasionally cows, and to help wean young cattle by preventing suckling. Nose rings are used on pigs to discourage rooting. Some nose rings are installed through a pierced hole in the nasal septum or rim of the nose and remain there, while others are temporary tools.

<span class="mw-page-title-main">Stable vices</span>

Stable vices are stereotypies of equines, especially horses. They are usually undesirable habits that often develop as a result of being confined in a stable with boredom, hunger, isolation, excess energy, or insufficient exercise. They present a management issue, not only leading to facility damage from chewing, kicking, and repetitive motion, but also leading to health consequences for the animal if not addressed. They also raise animal welfare concerns.

<span class="mw-page-title-main">Bitless bridle</span> Type of horse equipment

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.

<span class="mw-page-title-main">Lead (tack)</span> Line used to lead a horse

A lead, lead line, lead rope (US) or head collar rope (UK), is used to lead an animal such as a horse. Usually, it is attached to a halter. The lead may be integral to the halter or, more often, separate. When separate, it is attached to the halter with a heavy clip or snap so that it can be added or removed as needed. A related term, lead shank or lead chain refers to a lead line with a chain attached that is used in a variety of ways to safely control possibly difficult or dangerous horses if they will not respond to a regular lead.

<span class="mw-page-title-main">Grimace scale</span> Method of assessing pain in non-human animals

The grimace scale (GS), sometimes called the grimace score, is a method of assessing the occurrence or severity of pain experienced by non-human animals according to objective and blinded scoring of facial expressions, as is done routinely for the measurement of pain in non-verbal humans. Observers score the presence or prominence of "facial action units" (FAU), e.g. Orbital Tightening, Nose Bulge, Ear Position and Whisker Change. These are scored by observing the animal directly in real-time, or post hoc from photographs or screen-grabs from videos. The facial expression of the animals is sometimes referred to as the pain face.
