About the Mustang

The Mustang is a free-roaming horse of the western United States: a hardy, medium-sized animal prized for sure-footedness, stamina and independence.

The Mustang roams free across the western United States. Its name traces back to the Spanish word mesteno, meaning a stray or feral animal. These horses descend from stock brought to the Americas by Spanish colonists, and over the centuries they spread across the open range, toughening up to cope with dry, unforgiving country.

The Mustang is not a breed in the closed-studbook sense familiar to owners of, say, a Boerperd or a Nooitgedacht pony. It is a population moulded by its environment, its bloodlines a mix of Spanish stock, ranch horses and old cavalry remounts. Generations on the range have produced a compact, tough animal that costs little to keep. Federal agencies in the US manage most of the surviving feral herds today, and adopted Mustangs go on to work as trail, ranch and endurance horses, a discipline well known to South African riders through events run under SAEF endurance rules.

A typical Mustang stands between 14 and 15 hands, with hard, dense hooves that often need little in the way of shoeing. Its temperament runs toward independence and caution, the legacy of generations that had to read the veld, or its American equivalent, to survive.

Who the Mustang suits

A Mustang suits an owner with time, patience and a fair amount of horse sense already banked. Animals taken straight off the range need careful, unhurried gentling before they will accept handling of any kind. Once settled, though, a Mustang makes a sound, low-maintenance partner for trail riding, farm work and long-distance riding. Newcomers to horse ownership are generally better off with a Mustang that has already been started under saddle.

History and origin of the Mustang

Mustangs descend from Spanish horses brought to the Americas in the 1500s, spreading across the western range for centuries before US federal protection in 1971.

The Mustang's story begins with horses the Spanish shipped to the Americas from the early 1500s onward. Some escaped, some were traded away, lost or captured, and free-roaming herds took shape across the southern plains and the Southwest.

Native peoples of the plains took up the horse through the 1600s and 1700s, and horse culture spread north and west from there. Herds swelled as escaped and released animals joined the wild population, later drawing in ranch horses and cavalry stock. By the 1800s, sizeable numbers of free-roaming horses covered the western United States.

Numbers dropped sharply from the late 1800s into the 1900s. Horses were rounded up for slaughter, for sale, and simply to clear grazing land for cattle and sheep. Public unease over these practices built through the middle of the twentieth century, not unlike the conservation debates South Africans will recognise from the country's own wildlife management history.

In 1971 the United States passed the Wild Free-Roaming Horses and Burros Act, placing free-roaming Mustangs on designated public land under federal protection and management. The Bureau of Land Management now oversees many of these herds, using gathers and an adoption scheme to keep herd numbers in balance with the range.

Appearance and breed standard of the Mustang

The Mustang is a compact, muscular horse of roughly 14 to 15 hands, with a short back, strong legs, hard hooves and a broad spread of coat colours.

The Mustang is compact and well-muscled, built for endurance rather than sheer size. It carries a solid chest and hindquarters, a short back, and clean, strong legs. The hooves are typically hard and dense, an adaptation to rocky, dry ground, and many Mustangs are ridden barefoot without issue.

Because the population is not bred to a single closed standard, conformation differs from herd to herd. Horses from different ranges vary in head shape, height and colour, a reflection of the mixed Spanish and domestic stock behind them.

Coat and colours

Mustangs turn up in almost every horse colour going. Bay, dun, black and chestnut are common, and patterns such as pinto and roan crop up regularly. Dun and grullo coats, with a dark dorsal stripe and sometimes barring on the legs, point to the Spanish ancestry running through many herds. The coat stays short in warm months and thickens up for winter out on the open range.

Temperament and behaviour of the Mustang

Mustangs are independent, alert and confident horses that bond strongly once trust is earned, though range-born animals need patient gentling first.

Mustangs are independent and alert by nature. Generations spent on the range have sharpened their awareness of any change nearby, and left them wary of anything unfamiliar. A horse born free reads people much as it once read the land, so trust has to be earned over time rather than handed over on day one.

Once a Mustang accepts a handler, it tends to settle into a loyal, steady partner. Many adopters report a strong bond forming, and a horse that turns out calm and willing under saddle. Around other horses, Mustangs are sociable and slot into herd life without fuss, since living in a herd is simply their natural state.

With strangers, a Mustang usually stays watchful until it has sized the person up. A confident, consistent approach from the handler helps the horse relax. These are not animals that respond well to being rushed or handled roughly.

Caring for and grooming a Mustang

Mustangs are low-maintenance horses needing regular hoof care, daily turnout and exercise, plus shelter from extreme weather.

Grooming

  • Brush regularly to clear dirt and check the skin and coat
  • Pick out the hooves daily and watch for stones or cracks
  • Book farrier checks every 6 to 8 weeks, even for a barefoot horse
  • Keep the mane and tail free of tangles and burrs
  • Step up grooming during the seasonal shed

Exercise

  • Provide daily turnout in a paddock or camp
  • Ride or work the horse several times a week to keep it fit
  • Mix trail, arena and groundwork to vary the routine
  • Give it room to move, since Mustangs are used to covering real ground

Environment

Mustangs cope with a wide range of weather and need less cosseting than many breeds. They still need clean water, a dry spot to stand, and shelter from wind, harsh sun and storms. A camp with a run-in shed suits them well. Fencing should be safe and secure, particularly for a recently gentled horse still inclined to test its boundaries.

Feeding and nutrition for the Mustang

Mustangs thrive on forage, grass and hay, and generally need less concentrated feed than other horses because they hold weight easily.

Mustangs evolved on thin range forage and hold condition on less feed than most domestic breeds. The diet should be built around good grass and hay, fed in amounts matched to the horse's size, age and workload. Constant access to clean water and a salt or mineral source rounds out the basics.

Because Mustangs hold weight so easily, owners need to watch for over-feeding. Too much grain or rich pasture can lead to obesity and to laminitis, a painful hoof condition. Many Mustangs in light work need little or no concentrate at all.

General feeding guide
Life stageAmount per dayMeals
Foal (weaned)Forage plus a small balanced ration by weight3
Adult, light work1.5 to 2% of body weight in forage2
Adult, hard workForage plus added concentrate as needed2 to 3
SeniorEasy-to-chew forage, soaked feed if needed2 to 3

Treats and supplements

Most Mustangs on decent forage need very little extra. A salt block and a balanced mineral supplement cover the common gaps where local grass or hay falls short on nutrients. Treats such as carrots or apples are fine in small amounts. Check with a vet before adding supplements, since over-supplementing can do more harm than good.

Health and lifespan of the Mustang

Mustangs rank among the hardiest of horses, often living 25 to 30 years, with sound feet and good resistance to many common equine problems.

Mustangs are known for their hardiness. Natural selection on the range favoured sound, disease-resistant animals, and the result is a horse that tends to stay healthy on basic care alone. Many live 25 to 30 years, and their dense hooves and tough constitution help them sidestep problems that trouble more delicate breeds.

Good health still depends on routine care, though. The main risks for a Mustang are usually diet-related, such as weight gain and laminitis from rich feed, rather than inherited disease.

Conditions to watch
ConditionSignsNote
LaminitisLameness, heat in the hoof, reluctance to moveOften linked to over-rich diet; manage weight
ObesityExcess fat, low energyCommon when feed exceeds workload
Dental problemsDropping feed, weight lossRoutine dental checks prevent most issues
ColicRestlessness, rolling, no manureVeterinary emergency; provide steady forage and water
Internal parasitesPoor coat, weight lossManage with a vet-guided worming plan

Preventive care

  • Yearly veterinary exam and vaccinations
  • Dental check at least once a year
  • Regular farrier visits
  • A worming programme based on faecal testing
  • Steady, forage-based feeding to control weight

Training a Mustang

Mustangs are intelligent and trainable but need patient, trust-based handling, especially range-born horses new to people.

Mustangs learn fast and remember what they are taught, but they think for themselves and will not be bullied into work. Training comes down to trust. A horse fresh off the range has had little or no contact with people and needs gentling before any saddle work starts. Once that trust is built, many Mustangs turn into calm, willing, dependable mounts.

Consistency counts for more than force. A handler who stays clear, fair and unhurried gets the best out of a Mustang. Pushing too hard, or punishing fear, tends to set the training back.

Basics

  1. Spend time near the horse so it grows used to your presence
  2. Build acceptance of touch, the halter, and being led
  3. Add groundwork such as yielding, leading and standing tied
  4. Introduce tack and saddle pressure in small steps
  5. Start under saddle once the horse is calm and responsive on the ground
  6. Move on to trail, arena and task work as confidence builds

Breeding the Mustang

Mustangs reach breeding maturity at a few years old, carry a single foal after an 11-month gestation, and raise hardy young weaned at around six months.

On the range, Mustangs breed naturally in herd bands, with a stallion running with a group of mares. Mares usually reach breeding maturity by two to three years of age, though many are not put in foal until they are older and fully grown. Breeding tends to follow the seasons, with most foals born in spring when grass is plentiful.

Gestation runs about 11 months and produces a single foal. Twins are rare, and risky, in horses. Range-born foals are up and moving within hours of birth, an adaptation that lets them keep pace with the herd and avoid predators.

Mares raise their foals within the band, and the young nurse for several months before weaning at around six months. Colts and fillies stay with the herd until they mature, after which young stallions often move off to form bachelor groups or to win mares of their own. Mustangs raised for adoption are usually gentled and weaned under managed conditions.

Mustang FAQs

Common questions about Mustang size, temperament, care, lifespan, suitability and where to find one.

How big does a Mustang get?

Mustangs are medium-sized horses, usually 14 to 15 hands tall and weighing about 363 to 454 kg (800 to 1000 lb). Build and height vary between herds.

What is the Mustang's temperament like?

Mustangs are independent, alert and confident. They can be wary of new people at first, but bond strongly and become loyal, steady partners once they trust a handler.

Are Mustangs hard to care for?

Day to day, they are low-maintenance and hardy, with tough hooves and a healthy appetite for forage. The harder part is the early gentling of a range-born horse, which takes time and skill.

How long do Mustangs live?

Mustangs commonly live 25 to 30 years, which is long for a horse, thanks to their hardy constitution and sound feet.

Are Mustangs good for beginners?

A range-born Mustang is best left to experienced handlers. A Mustang that has already been gentled and started under saddle can suit a less experienced owner with good support around them.

Where can I get a Mustang?

In the United States, free-roaming Mustangs are managed by the Bureau of Land Management and can be obtained through its adoption programme. Already-trained Mustangs are also available from private owners and trainers. South African buyers would need to look into import requirements through the relevant SAEF-recognised channels before bringing one in.

Can a Mustang go barefoot?

Many Mustangs have hard, dense hooves and manage well without shoes. Regular farrier checks are still needed to keep the feet balanced and sound.
