The overo pattern is one of three coat patterns in American Paint Horses (APHs) recognized by the American Paint Horse Association (APHA), along with Tobiano and Tovero. Among Overo variations, the frame overo subtype stands out for its distinctive markings....

Platelet-Rich Plasma (PRP) is a regenerative therapy used to treat horses with tendon and ligament injuries. PRP is a blood preparation where plasma, the water and protein component of blood containing no cells, is mixed with highly concentrated platelets and...

Pulsed electromagnetic field (PEMF) therapy is a treatment modality for horses where a machine produces pulses of electromagnetic fields directed at a specific part of the body. Research suggests that PEMF can improve bone healing rates, regenerate and protect cartilage...

Habronematidosis or habronemosis, more commonly known as summer sores, is a parasitic skin infection that can occur in horses. As the name implies, summer sores usually occur during the summer months.

Chiropractic care for horses is a form of manual therapy commonly used in veterinary treatment protocols for lameness. Chiropractic treatment focuses on joint mobilization and manipulation to reduce pain, improve symmetry, and increase range of motion.

Exertional Rhabdomyolysis (ER), commonly known as tying-up or azoturia, is an exercise-induced condition in horses characterized by the excessive breakdown of muscle tissue. This results in muscle spasms, pain and impaired performance following bouts of exercise. [1] In severe cases,...

Leptospirosis is a bacterial infection that is commonly spread to horses through direct contact with contaminated food and water sources. While there are many different species of the Leptospira bacteria, symptoms in horses are most commonly caused by Leptospira interrogans.

Sesamoiditis in horses refers to pain and injury around the sesamoid bones, pairs of small triangular bones found at the back of the fetlock. Inflammation in this area can cause pain and changes to the bony structure of the sesamoid...

Sacroiliac pain is a common cause of poor performance and low-grade lameness in performance horses. The sacroiliac joint is the point on the horse’s body where the pelvis and the spine connect, playing an important role in their stride.

Pedal osteitis in horses is a condition characterized by inflammation and damage to the pedal (coffin) bone within the hoof. Affected horses can experience pain and lameness, which may be worse after exercise or hoof trimming. Pedal osteitis typically develops...

Sidebone in horses is a common condition that affects the collateral cartilages of the hoof. It occurs when the normally flexible cartilage plates in the horse's hoof gradually become hardened and calcified into bone. According to research, an estimated 80%...

Canker in horses, also called equine proliferative pododermatitis is a condition that causes rapid proliferation of keratin, the main component of the hoof wall and sole. The proliferation forms long fronds of keratin, usually around the frog of the hoof.

Buttercup poisoning in horses occurs when they ingest protoanemonin, a toxin produced by the buttercup plant. Although relatively rare, the ingestion of this flowering weed results in irritation to the horse’s mouth and digestive tract.

Keratomas in horses are abnormal growths or benign tumors that develop within the hoof capsule, potentially resulting in lameness and discomfort. These non-cancerous masses comprise overgrowths of keratin, typically forming near the coronary band.

Synovial infections in horses refer to infections in the synovial structures, which include joints, bursae, and tendon sheaths. These infections can be severe and potentially career-ending for equine athletes. Most horses develop synovial infections from wounds over top of a...

Ionophore toxicosis, a severe and often fatal condition in horses, arises from the ingestion of ionophores, antibiotic compounds that are common in livestock feeds. Common ionophores in livestock feeds include monensin, lasalocid and salinomycin. These antibiotics increase growth rates in...
