Equid Types: Horses, Ponies, Donkeys and Mules

Discover the main equid categories and a selection of representative breeds. Riding horses, draft horses, ponies, donkeys and miniature horses each have distinct origins, conformations and abilities.

How are equid breeds classified?

The term equid refers to animals belonging to the horse family, including horses, ponies, donkeys and hybrids such as the mule.

Breeds may also be grouped according to their conformation, history or traditional use. This includes riding horses, primarily developed to be ridden, and draft horses, bred for pulling loads and performing demanding work.

This page presents a selection of breeds from each category. Dedicated category pages allow you to explore all the breeds belonging to a particular equid type.

Horse

The horse (Equus ferus caballus) is the most widespread domesticated equid in the world. Horse breeds differ in their origin, conformation, temperament, and abilities, whether they are bred for riding, sport, work, leisure, or the preservation of historical bloodlines.

Gaited Horse

Gaited horses possess one or more natural intermediate gaits, such as the tölt or running walk, providing exceptionally smooth and comfortable rides. These breeds are highly valued for trail riding, endurance, and long-distance travel.

Riding Horse

Riding horses include breeds primarily developed for mounted work and equestrian activities. They excel in disciplines such as dressage, show jumping, eventing, endurance, leisure riding, and working equitation, combining athleticism, balance, and rideability.

Draft Horse

Draft horses are powerful breeds developed for pulling heavy loads, agricultural work, forestry, and carriage driving. Their strength, calm temperament, and reliability also make them popular for recreational driving, heritage events, and sustainable land management.

Miniature Horse

Miniature horses are true horses selectively bred for their small size while maintaining the proportions of a full-sized horse. They are commonly used as companion animals, in shows, animal-assisted therapy, educational programs, and, in some cases, as service animals.

Primitive Horse

Primitive horses are breeds that have retained many ancestral characteristics through limited selective breeding. They are generally hardy, resilient, and well adapted to harsh environments, often displaying primitive markings such as dorsal stripes and leg barring.

Mule

The mule is a hybrid resulting from the cross between a male donkey and a female horse. Known for its strength, endurance, intelligence, and longevity, it has been used for centuries in agriculture, transport, pack work, mountain trails, and demanding terrain.

Pony

Ponies are small equids, generally measuring no more than 148 cm (14.2 hands) at the withers, recognized for their strength, intelligence, and versatility. Pony breeds are widely used for children’s riding, equestrian sports, carriage driving, leisure riding, endurance, and sometimes agricultural work.

Frequently asked questions about equid types

What is the difference between a horse and a pony?

The distinction is primarily based on height at the withers, with a commonly used limit of 148 cm, or 14.2 hands, without shoes. Conformation and individual breed standards are also taken into account.

What is the difference between a riding horse and a draft horse?

A riding horse is primarily bred to be ridden for leisure, sport or mounted work. A draft horse generally has a stronger and more powerful conformation adapted to pulling loads and performing physically demanding work.

Is a mule a horse breed?

No. A mule is a hybrid usually produced by crossing a male donkey with a female horse. Mules are valued for their strength, endurance, intelligence and sure-footedness.

Is a miniature horse a pony?

Not necessarily. Despite its small size, a miniature horse is bred to retain the general proportions of a full-sized horse, rather than the compact conformation commonly associated with many pony breeds.
