  • 20-metre circle

    The largest standard circle in dressage, 20 metres in diameter, filling the full width of the arena with four touch points.

    See also: Volte

  • Agouti

    The gene locus that decides where black pigment goes. The dominant form pushes black to the points (bay); the recessive form spreads it over the whole body (black).

    See also: Extension (red factor), Points, Base colour

  • Arena letters

    The fixed letters along the edge and on the centre line of the arena that serve as reference points; the small arena has eight outer letters (A-K-E-H-C-M-B-F) and D-X-G on the centre line.

    See also: Centre line

  • Bald face

    A very broad facial marking covering most of the face and extending over at least one eye and usually both nostrils.

  • Base colour

    One of the three colours that all other horse colours are built on: chestnut, bay or black. Dilutions and patterns work on top of a base colour.

    See also: Dilution gene, Points

  • Bell boots

    Bell-shaped protectors around the heel bulbs that guard the front hooves against being stepped on by the hind legs.

    See also: Brushing boots

  • Blaze

    A broad white stripe running down the forehead and nose. Narrower it is a stripe; very broad it becomes a bald face.

    See also: Marking, Star

  • Body brush

    A brush with short, soft bristles that smooths the coat, picks up fine dust and spreads skin oils for shine.

    See also: Dandy brush

  • Body language

    The combination of ear position, head height, tail and posture that hints at a horse's attention or tension; a single sign never proves a particular emotion.

    See also: Flehmen response

  • Brushing boots

    Leg boots that protect the inside of the lower leg from being struck by the other leg.

    See also: Tendon boots

  • Cannon

    The straight bone between the knee or hock and the fetlock, with the flexor tendons behind it; heat or swelling here is always a warning.

    See also: Fetlock

  • Canter

    A three-beat gait with three hoof beats per stride, followed by a moment of suspension; the leading foreleg sets left or right lead.

    See also: Gallop

  • Cantle

    The raised back of the saddle seat; a higher cantle gives a deeper dressage seat, a lower one more freedom for jumping.

    See also: Pommel

  • Centre line

    The straight line from A to C dividing the arena into two equal halves; every test starts by entering along the centre line, usually with a halt at X.

    See also: Arena letters

  • Champagne

    A dominant dilution gene that dilutes black to brown and red to gold, with a typical metallic sheen, pinkish mottled skin and amber eyes.

    See also: Dilution gene

  • Colic

    A collective name for abdominal pain in the horse; risk rises with lots of concentrates, little forage and sudden feed changes. When suspected it is a veterinary emergency.

    See also: Concentrates, Forage (roughage)

  • Concentrates

    Concentrated, starch- and sugar-rich feed such as grain or pellets; too much at once raises the risk of colic, laminitis and ulcers.

    See also: Forage (roughage)

  • Coronet

    A narrow white band just above the hoof; the lowest of the leg markings.

  • Cream

    A dilution gene that dilutes red to yellow. One copy gives palomino (on chestnut) or buckskin (on bay); two copies give an almost white colour such as cremello. Cream is dominant with a dosage effect.

    See also: Dilution gene, Heterozygous, Homozygous

  • Croup

    The curve of the pelvis between the loin and the tail root, holding the large muscles that provide most of the push.

  • Curb bit

    A bit that works through leverage via the shanks and a curb chain, often used together with a snaffle in a double bridle (Weymouth and bradoon).

    See also: Snaffle bit

  • Curry comb

    A handy tool with rubber or plastic nubs to loosen dirt, mud and dead hair, usually in small circles on the muscled areas.

    See also: Dandy brush

  • Dandy brush

    A brush with long, stiff bristles to flick away the loosened dirt and dust, mainly on the large muscled areas.

    See also: Curry comb, Body brush

  • Dilution gene

    A gene that lightens a base colour. Some dilute only red, others only black, others both. Examples: cream, dun, champagne and silver.

    See also: Cream, Dun, Champagne, Silver

  • Dominant

    A trait that shows with a single copy of the gene. Cream, dun and grey are for example dominant.

    See also: Recessive, Heterozygous

  • Dorsal stripe

    A dark stripe running along the topline, from withers to tail. The clearest sign of the dun gene and the main difference from a buckskin.

    See also: Dun, Primitive markings

  • Dun

    A dominant dilution gene that lightens the body and adds primitive markings such as a dorsal stripe. Head, lower legs, mane and tail stay undiluted.

    See also: Dorsal stripe, Primitive markings

  • Ermine marks

    Small dark spots within a white leg marking, usually just above the hoof around the coronet.

    See also: Coronet

  • Extension (red factor)

    The gene locus that decides whether a horse can make black pigment. Two recessive e alleles give a chestnut: the horse then makes only red pigment.

    See also: Agouti, Base colour, Recessive

  • Farrier

    The professional who trims the hooves, fits shoes and helps with corrective hoof care.

    See also: Horseshoe

  • Fetlock

    The hinge joint below the cannon that absorbs a lot of shock at every stride, and is therefore prone to wear.

    See also: Cannon

  • Flehmen response

    Raising the head and curling the upper lip to route inhaled scent to the vomeronasal organ; a normal sensory mechanism, not an emotion.

    See also: Body language

  • Fly rug

    A light, fine-mesh rug that lets air through but keeps biting insects off in summer.

    See also: Turnout rug

  • Forage (roughage)

    Fibre-rich feed such as grass, hay and haylage that should make up most of the ration; it keeps digestion healthy and lowers the risk of colic and ulcers.

    See also: Concentrates, Hay

  • Frog

    The V-shaped, rubbery structure in the middle of the underside of the hoof that helps absorb shock and pumps blood back up the leg with each step.

    See also: Sole

  • Gallop

    The fastest gait: an asymmetric four-beat movement in which each leg lands separately, followed by a moment of suspension.

    See also: Canter

  • Girth

    The strap that passes under the belly and holds the saddle in place.

  • Grey

    Not a fixed colour but a process: the horse turns whiter year after year, whatever colour it was born. The skin stays dark.

    See also: Roan

  • Hay

    Dried grass with a low moisture content, a basic form of forage for horses.

    See also: Haylage, Forage (roughage)

  • Haylage

    Wrapped, part-dried grass with a higher moisture and thus lower fibre content per kilo than hay, so the amount fed must be adjusted.

    See also: Hay

  • Heterozygous

    Carrying two different versions of a gene (for example one cream and one normal). With a dominant gene a heterozygous horse already shows the trait.

    See also: Homozygous, Dominant

  • Hock

    The large angular joint in the middle of the hind leg that takes huge forces on push-off; it corresponds to our ankle.

  • Homozygous

    Carrying two identical versions of a gene. With cream, homozygous (two copies) gives a cremello instead of a palomino.

    See also: Heterozygous, Recessive

  • Hoof pick

    A curved hook to remove mud, manure and stones from the hoof, working from heel to toe and away from the sensitive frog.

    See also: Frog

  • Horseshoe

    A usually metal shoe fixed under the hoof to protect the hoof wall from wear.

    See also: Farrier

  • Laminitis

    A painful inflammation and damage of the laminae that connect the hoof wall to the coffin bone; severe cases can lead to rotation of the coffin bone. Causes include carbohydrate overload and obesity.

    See also: White line, Concentrates

  • Licking and chewing

    Non-nutritive chewing and licking of the lips, often seen after a tense moment; its meaning is scientifically contested and not a sure sign of submission or calm.

    See also: Body language

  • Loading

    Calmly letting the horse enter the trailer or lorry; safe pre-travel checks of floor, lights and brakes are part of it.

    See also: Trailer

  • Long-reining

    Steering the horse from the ground with two long reins while the handler walks behind, slightly to one side.

    See also: Lungeing

  • Lungeing

    Moving the horse in a circle around the handler on a long line (the lunge), for training and exercise from the ground.

    See also: Lungeing cavesson, Long-reining

  • Lungeing cavesson

    A sturdy padded noseband with rings to attach the lunge line, giving more control than a halter without acting on the mouth.

    See also: Lungeing

  • Marking

    A congenital white marking on the head or legs, such as a blaze, star or white sock. Markings are separate from the coat colour itself.

    See also: Blaze, Star, Snip

  • Martingale

    An auxiliary strap that limits how high the horse carries its head; a running martingale works via rings on the reins, a standing one via the noseband.

  • Noseband

    The band that runs over the horse's nose; the simplest form is the cavesson, other types are the flash, the drop and the grackle.

  • On the bit

    A posture in which the horse moves in balance with the poll as the highest point, the head near vertical and a soft, even contact with the hand.

    See also: Transition

  • Pace

    A lateral two-beat gait in which the two legs on the same side move together, instead of diagonally as in the trot.

    See also: Tolt

  • Pearl

    A recessive dilution gene that shows only in double dose or together with cream, then giving a pale, even colour and sometimes light eyes.

    See also: Cream, Recessive

  • Points

    The extremities of a horse: mane, tail, ear rims and lower legs. On a bay the points are black, and on a buckskin too.

    See also: Agouti, Base colour

  • Poll

    The highest point of the neck, just behind the ears, where the head hinges on the neck and the bridle headpiece rests.

  • Pommel

    The raised front of the saddle, where the tree comes together at the front and the leg can move freely forward.

    See also: Cantle

  • Primitive markings

    The ancient markings that come with dun horses: the dorsal stripe, horizontal zebra bars on the legs and sometimes shoulder stripes.

    See also: Dorsal stripe, Dun

  • Quartering

    A quick grooming before riding in which the rug is folded back in sections to keep the horse warm; feet, eyes, nose and dock are cleaned.

    See also: Curry comb

  • Recessive

    A trait that shows only when a horse has two copies of the gene. Chestnut and pearl are for example recessive.

    See also: Dominant, Homozygous

  • Roan

    White and coloured hairs mixed on the barrel, with a coloured head and legs. Unlike a grey this does not change with age.

    See also: Grey

  • Sabino

    A white pattern with irregular, ragged markings on the legs, belly and face, often with a lot of intermixed white hairs (roaning).

    See also: Roan, Marking

  • Serpentine

    A series of equal loops that wind from one long side to the other; at each crossing of the centre line the bend, and so the rein, changes.

    See also: Centre line

  • Silver

    A dominant gene that lightens only black, not red. Mane and tail turn silvery. On chestnut it is invisible. Linked to the eye condition MCOA.

    See also: Dilution gene

  • Snaffle bit

    A bit that works with direct pressure on the mouth, without leverage; the most common bit and the only one allowed at the lower dressage levels.

    See also: Curb bit

  • Snip

    A small white patch on or between the nostrils, separate from any blaze.

    See also: Marking, Blaze

  • Sock

    A white leg marking that reaches from the hoof to about halfway up the cannon, above the fetlock joint. White reaching higher, to the knee or hock, is a stocking.

  • Sole

    The hard, concave underside of the hoof that protects the internal structures and helps bear the horse's weight.

    See also: Frog, White line

  • Star

    A small white patch on the forehead. Larger, it is called a star.

    See also: Marking, Blaze

  • Stocking

    A white leg marking that reaches to the knee (foreleg) or hock (hind leg), higher than a sock.

    See also: Sock

  • Tendon boots

    Boots that cover the back of the forelegs, over the flexor tendons, against knocks.

    See also: Brushing boots

  • Tobiano

    A pinto pattern with large, rounded white patches that cross over the back, usually with white legs and a mostly coloured head.

    See also: Marking

  • Tolt

    A comfortable lateral four-beat gait with no suspension, in the same footfall order as the walk but much faster; typical of the Icelandic horse.

    See also: Pace, Walk

  • Trailer

    A towed vehicle to transport one or more horses behind a car, with a ramp for loading and unloading.

    See also: Loading

  • Transition

    A change of gait or of tempo within a gait, for example from walk to trot; in dressage it is judged on smoothness and balance.

    See also: On the bit

  • Travel boots

    Boots or wraps that protect the legs during transport from knocks and kicks against the walls.

    See also: Trailer

  • Trot

    A two-beat gait in which diagonal pairs of legs move together, with a short moment of suspension between the two beats.

    See also: Walk, Canter

  • Turnout rug

    A waterproof, breathable rug for the field that protects against rain, wind and cold.

    See also: Fly rug

  • Volte

    A small circle of 6, 8 or 10 metres in diameter; a figure larger than 10 metres is called a circle.

    See also: 20-metre circle

  • Walk

    The slowest gait: a four-beat movement with no moment of suspension, with two or three hooves always on the ground.

    See also: Trot, Canter

  • White line

    The visible junction on the underside of the hoof between the hoof wall and the sole, where the laminae attach the wall to the foot.

    See also: Laminitis

  • Withers

    The ridge where the neck meets the back; the height of the horse is measured here.
