American Paint Horse

About the breed

The American Paint Horse (Equus ferus caballus) is a muscular, Quarter Horse-type riding horse from North America, recognised at first glance by the white patches in its coat. A spotted coat alone does not make a Paint, though: the American Paint Horse Association (APHA) registers only horses whose parents are both registered with APHA, AQHA or the Thoroughbred studbook of The Jockey Club. Under the Slovenian breeding programme it reaches 142–165 cm at the withers, and its reputation is that of a calm, kind all-rounder, seen most often in Western riding.

From the spotted horses of the Old West to a studbook of its own

The Paint Horse's roots go back to the 16th century, when the Spanish brought horses to North America, many of which were turned loose when the Spanish went home. The Slovenian Quarter Horse Association (SIQHA) describes how spotted horses were highly prized by Native American peoples, and how settlers later caught and tamed them for ranch work, where usefulness was the only real selection criterion.

Spotted stock horses got a studbook of their own relatively late. According to Horse&Rider magazine, the American Quarter Horse Association (AQHA) decided in the 1940s not to register stock horses with white markings above the hocks and knees. Horsewoman Rebecca Tyler Lockhart gathered like-minded breeders, and on 16 February 1962 a group of 16 met at a café in Gainesville, Texas, to found the American Paint Stock Horse Association. In 1965 it merged with the American Paint Quarter Horse Association to form today's American Paint Horse Association (APHA). Registration No. 1 belongs to Bandit's Pinto, a black tobiano foaled in 1959.

The breed's studbook is kept by APHA, based in Fort Worth, Texas, which describes itself as the second-largest equine breed association in the world and says it has registered more than a million horses. In Slovenia, SIQHA has been the recognised breeding organisation for the American Paint Horse since 2018; its breeding programme was written together with the Veterinary Faculty of the University of Ljubljana. According to the programme, Slovenia had more than 110 horses of the breed at the end of 2017, with foals registered there continuously since 2007.

A pedigree breed, not just a colour: APHA rules

The Paint is a breed defined by both bloodline and coat pattern. APHA requires both parents to be registered with APHA, AQHA or The Jockey Club. A horse with at least one APHA parent is always eligible for registration, whatever its white markings. A foal with only Quarter Horse or Thoroughbred parents must meet minimum colour requirements and have a colour and pattern DNA panel done. The Slovenian breeding programme adds explicitly that crosses with any other breed are not allowed.

APHA calls the colour requirement a "natural Paint marking": an area of solid white hair with some unpigmented skin underneath that the horse had at birth. For the Regular Registry the marking must be more than 2 inches (about 5 cm) and lie within a defined qualifying area, mostly above the knees and hocks. Since 1 January 2022 every registration also requires parentage verification by DNA.

A Paint Horse can also be entirely solid-coloured. APHA calls a horse that qualifies by bloodline but shows no white markings or white-spotting genetics a Solid Paint-Bred rather than entering it in the Regular Registry. It can later move to the Regular Registry on the strength of DNA-confirmed pattern genes combined with typical Paint traits, such as blue eyes or a two-tone mane, or on pedigree, with two APHA parents and three connected generations of APHA breeding.

SIQHA notes that solid Paints are often mistaken for Quarter Horses because the breed characteristics are the same, and that a solid horse can still pass a pattern on to its foals.

Tobiano, overo and tovero: how to recognise the pattern

Paint coat patterns fall into three groups, tobiano, overo and tovero, and each can range from minimal to very loud. APHA describes tobiano as a dominant white-spotting pattern caused by the Tobiano allele, so a tobiano horse must have a tobiano or tovero parent. Its white often crosses the topline between the withers and the tail, the legs are usually white at least below the knees and hocks, the spots are regular ovals or rounds, and the head is typically marked like a solid horse's, with a star, stripe, blaze or snip.

Overo is an umbrella term for patterns caused by one or more of more than 30 white-spotting genes other than tobiano, including frame overo, splashed white and sabino. On an overo the white rarely crosses the back, at least one leg is usually dark, the spots are irregular and scattered, and the head often carries extensive white (bald-faced, apron-faced or bonnet-faced). A tovero carries tobiano plus at least one overo gene and often has dark ears, dark patches around the mouth, on the chest and flanks, and one or two blue eyes. Any base colour is possible underneath; PetMD gives black, brown, chestnut, grey, bay roan, palomino and buckskin as examples.

Size and build: a compact, muscular stock horse

SIQHA's breeding programme gives the Paint a height at the withers of 142–165 cm, slightly wider at the lower end than the 145–165 cm the Slovenian programme sets for the Quarter Horse; PetMD gives 14 to 16 hands, or about 142–163 cm. Weight is not fixed by any studbook. PetMD's vet-reviewed profile gives 950–1,200 lb (about 430–545 kg), the same range Britannica gives for the Quarter Horse, whose type the Paint shares. What an individual horse weighs depends on type, sex and condition.

APHA describes the breed as a stock-type horse, and the breeding programme spells it out: a short, wedge-shaped head with well-developed jaw muscles, a rectangular, wide and deep body with a short back and very well-muscled hindquarters, correct, clean legs with sound hooves, and elastic movement driven by a very active hind end.

Temperament: calm, kind and willing to learn

Breeders and veterinary sources alike describe the Paint as calm, friendly and trainable. The Slovenian breeding programme lists a kind heart, a trusting and balanced character, a quiet temperament and intelligence among the breed's special traits, and the breeding goal gives temperament particular weight. PetMD's vet-reviewed profile describes the Paint as relaxed, friendly and intelligent, and eager to learn.

Uses: from the Western arena to the racetrack

The Paint is above all a Western horse, but its uses are broader. SIQHA's breeding programme calls it a horse for the whole family, suited to all competitive disciplines and to driving, and especially to Western disciplines; the breeding goal is a versatile horse for leisure and competition alike. Worldwide, Paints compete in every Western discipline and in some English disciplines such as show jumping, as well as in racing. APHA also lists racing among its competition programmes.

Paint or pinto: what is the difference?

Paint is a breed; pinto is a coat pattern and also the name of a colour registry. The Pinto Horse Association of America (PtHA) explains that Paint Horses are limited to registered Paint, Quarter Horse and Thoroughbred bloodlines, while a Pinto can come from many breeds, including the Arabian, American Saddlebred, American Miniature Horse, Tennessee Walking Horse and American Shetland Pony. Horse&Rider calls PtHA a true colour breed that requires no particular pedigree, and a horse that meets APHA's colour requirements will usually also qualify for PtHA registration. Colour alone, in other words, does not make a Paint; the pedigree does.

By type, a Paint does not differ from a Quarter Horse: SIQHA stresses that it is the same in origin, appearance and breed traits, only coloured, with its registry kept by APHA.

Paint Horses for beginners and children: under what conditions?

Conditionally. The coat draws many people in, but for a beginner or a child what counts is the horse's age and schooling. An older, quiet Paint with plenty of mileage can be a dependable partner for a novice who rides under an instructor, provided the horse has suitable work; a young or under-schooled horse is the wrong choice for someone taking their first steps in the saddle. Children around horses need constant adult supervision. When buying, an individual horse with a known history matters more than the breed or the pattern.

Care: white hair, skin, hooves and teeth

Caring for a Paint is the same as for any riding horse, with extra attention to the white areas. The Merck Veterinary Manual notes that photosensitisation – a skin reaction to sunlight triggered by certain plants or liver disease, not ordinary sunburn – mainly affects lightly pigmented or thinly haired skin such as the lips, eyelids and ear tips; the white patches over pink skin of a Paint are such areas. The DEFRA code of practice says horses living out need shelter from prevailing winds, summer sun and flies.

Hooves should be trimmed or re-shod as the farrier advises, usually every 4–8 weeks, and teeth checked at least once a year by a vet or qualified equine dental technician. DEFRA recommends agreeing a parasite control programme, including faecal worm egg counts, and a vaccination plan suited to the horse's age and use with your vet.

Feeding a Paint: hay, grass and care with concentrates

Hay and grass make up the bulk of a Paint's ration, with concentrates only as a top-up. The DEFRA code reminds owners that horses in a natural state graze and browse for 16–20 hours a day, which is why it recommends almost constant access to grass, hay or haylage outside working hours, alongside continuous access to clean, fresh water. If grazing falls short, extra feed, vitamins and minerals may be needed, but concentrates should not exceed what the horse needs for its work or any weight it has to gain. Restraint pays with this breed: PetMD notes that Paints gain weight easily when overfed, and in DEFRA's view a very overweight horse is as much a welfare concern as an underweight one. SIQHA's Slovenian programme recommends full-day grazing in the grazing season.

Exercise and turnout: work, grazing and shade

The Paint descends from horses that settlers tamed for ranch work, and it still needs regular ridden or groundwork, matched to its age and schooling, plus daily turnout. The DEFRA code says horses are herd animals that in the wild would live in relatively stable social groups; isolation can harm them psychologically, and other animals are only a fallback, because the company of other horses is by far the better option. Turnout in the field lets them graze and mix with their own kind, and may reduce the risk of weaving, crib-biting or box walking. Horses with extensive white patches should have shade available in the field.

Health: lethal white overo and genetic testing

The best-known inherited issue in the Paint Horse is lethal white overo (LWO). The Veterinary Genetics Laboratory at UC Davis explains that it is caused by a mutation in the EDNRB gene, the same variant that produces the frame overo pattern. A horse with one copy (N/O) shows frame overo and has no known intestinal problems, although it may be deaf. A foal with two copies (O/O) is born completely white, without the nerve cells its intestine needs, and dies soon after birth, as there is no treatment. Mating two carriers gives a 25% chance of an affected foal, and a carrier may show only minimal white, so the test reveals what the eye cannot.

APHA requires breeding stallions to have a Genetic Health Panel on file covering HYPP, HERDA, GBED, MH, PSSM1 and OLWS (APHA's name for lethal white overo), run by UC Davis VGL, its official testing partner. The first five also make up most of AQHA's panel for the Quarter Horse and are explained in our American Quarter Horse profile. A 2009 UC Davis case series described 14 deaf American Paint Horses: most had the splashed white pattern or a splashed white–frame blend, a few frame overo or tovero, and all had extensive white on the head and legs; most had two blue eyes. Deaf and suspected-deaf horses were nonetheless used successfully in various performance events. No source gives a lifespan for the Paint as such; the Merck Veterinary Manual's general figure for all horses is an average of 25–30 years.

Who suits a Paint, and what to check before buying

A Paint will best please a rider looking for a calm, muscular horse for Western riding, trail or leisure who also enjoys a coloured coat. Anyone drawn by the patches alone should know that other details say more when buying: APHA registration and pedigree, the horse's schooling and, for breeding stock, genetic test results, including the lethal white overo test. Day to day it needs a stable or open barn with daily turnout alongside other horses, good hay, shade in the field and regular work. A vet, a farrier and an equine dental technician should oversee its care; noting down vaccinations and their visits as they happen keeps the record straight.
