American Quarter Horse
About the Breed
The American Quarter Horse is one of the most popular and versatile horse breeds in the world. Known for its calm temperament, muscular build, and explosive speed over short distances, the breed is especially valued for ranch work, western performance events, and family riding.
Quarter Horses are famous for their ability to sprint a quarter mile faster than any other breed, which is where the breed gets its name. Today, they are best known as dependable all-around horses that excel in everything from trail riding and ranch work to barrel racing, reining, cutting, roping, and western pleasure.
Their willingness to work, strong trainability, and sensible nature make them a favorite among beginners, experienced riders, and professional trainers alike.
History
The American Quarter Horse developed in colonial America through the crossing of English horses with Spanish and Native American stock. Over time, breeders selected for speed, agility, “cow sense,” and a practical disposition.
These horses became deeply associated with life on the American frontier and later the cattle industry of the West.
The American Quarter Horse Association (AQHA) was established in 1940 to preserve and register the breed. Today, the Quarter Horse is one of the most heavily registered horse breeds in the world.
Height
Most American Quarter Horses stand about 14–16 hands tall.
Weight
Most weigh approximately 900–1,200 pounds.
Life Expectancy
With proper care, Quarter Horses commonly live 25–30 years or longer.
Overall Health
Quarter Horses are generally hardy and durable, but they are associated with several important inherited conditions.
Common concerns include:
Hyperkalemic Periodic Paralysis (HYPP)
Hereditary Equine Regional Dermal Asthenia (HERDA)
Glycogen Branching Enzyme Deficiency (GBED)
Polysaccharide Storage Myopathy Type 1 (PSSM1)
Malignant Hyperthermia (MH)
Navicular syndrome
Obesity and metabolic issues
Because these inherited conditions are well known in the breed, responsible breeders routinely perform genetic testing and disclose results.
Health Testing They Should Have
DNA parentage verification
HYPP testing
HERDA testing
GBED testing
PSSM1 testing
MH testing
Pre-breeding soundness and reproductive examination
Conformation and movement evaluation
