Breed characteristics

The Friesian is black with no white markings, stands typically 15 to 16 hands (60 to 64 inches, 152 to 163 cm) at the withers, and weighs 1,250-1,450 pounds. The breed is compact and muscular with good bone. Friesians have long, arched necks, small ears, and straight, long heads. They have sloping shoulders and hindquarters and a low-set tail. Limbs are short and strong, with feathering (long hair) on the lower legs. A Friesian horse also has a thick mane and tail. The breed is known for a brisk, high-stepping trot. The Friesian is considered willing, active, and energetic, but also gentle and docile.

Colour variations

Though Friesian horses have for decades been characteristically black, starting in 1991, an occasional chestnut foal was born. Friesch Paarden Stamboek (FPS) began to breed out the chestnut colour by requiring stallions to undergo genetic testing and denying registration of those that carry the chestnut genes. The former American Friesian Association, which closed its business in 2015 and was not affiliated with the FPS, allowed horses with white markings and chestnut colouration to be registered if purebred parentage could be proven.

Genetic disorders

Four genetic disorders are acknowledged by the industry that may affect horses of Friesian breeding - dwarfism, hydrocephalus, a tendency for aortic rupture, and megaesophagus. Genetic tests are available for the first two conditions. The Friesian is also among several breeds that may develop equine polysaccharide storage myopathy. About 0.25% of Friesians are affected by dwarfism, which results in horses with a normal-sized head, a broader chest than normal, an abnormally long back, and very short limbs. It is a recessive condition. Additionally, the breed has a higher-than-usual rate of digestive-system disorders, and a greater tendency to have insect bite hypersensitivity. Like other feathered draught breeds, they are prone to a skin condition called verrucous pastern dermatopathy and may be generally prone to having a compromised immune system. Friesian mares have a very high (54%) rate of retained placenta after foaling. Some normal-sized Friesians also have a propensity toward tendon and ligament laxity, which may be associated with dwarfism. The relatively small gene pool and inbreeding are thought to be factors behind most of these disorders.
