Horse Health

Mucous membranes play a critical role in assessing equine health. The most familiar mucous membranes are the gums, but these thin, moist tissues line various body cavities, including the eyes and genitals. In clinical settings and daily management, evaluating mucous...

Most horse owners know that poor air quality in dusty barns can cause coughing, nasal discharge, or laboured breathing in sensitive horses. But what happens when a horse seems worse outdoors—even on fresh green pasture? Just like people, horses can...

While horses are naturally well-adapted to colder climates, not all individuals cope equally well, and domestic management often interferes with their ability to maintain their internal body temperature. Clipping, restricted forage, inadequate shelter, chronic conditions, and other health factors all...

Timothy hay offers moderate energy and protein content, making it suitable for a wide range of horses. Depending on Timothy’s growing and harvesting conditions, it can be produced at varying nutritional levels to suit different horse’s needs- from growing and...

Horse chestnuts, sometimes called castors or night eyes, are small, rough patches of skin commonly found on a horse's legs. While easily overlooked, these structures have sparked curiosity for centuries due to their mysterious origin and unusual appearance. Leg chestnuts...

Ryegrass is a widely used forage for horses, most commonly provided in its annual and perennial forms. These grasses are known for their high yields and strong nutritional profiles, making them suitable for many types of horses. Although ryegrass can...

Blood work is one of the most valuable diagnostic tools available in equine veterinary medicine. Whether used to assess general health, diagnose illness, monitor chronic conditions, or evaluate performance issues, a simple blood test can reveal a wealth of information...

One of the most informative and widely used diagnostic procedures for evaluating the lower respiratory tract in horses is bronchoalveolar lavage (BAL). This is a minimally invasive technique that allows veterinarians to sample cellular components from deep lung tissue. By...

The New World screwworm (Cochliomyia hominivorax) is a highly destructive parasitic fly that poses a significant threat to equine health and welfare. Unlike typical fly larvae that feed on dead or decaying tissue, screwworm maggots consume living flesh, resulting in...

Respiratory dysfunction is a common and often overlooked issue in horses, with a variety of causes including infections, allergies, environmental irritants, and anatomical abnormalities. Horses depend on efficient lung function to meet the high oxygen demands of their large, athletic...

The coffin bone, also known as the distal phalanx or P3, sits at the very tip of the horse's limb, completely encased by the hard hoof wall. Its unique shape provides the foundation for weight-bearing and shock absorption with every...

First cutting hay is traditionally harvested in the spring and tends to be coarse and high in fiber. This is because the plants have had more time to mature, resulting in a higher concentration of structural carbohydrates. First-cutting hay is...

Equine inhalers are specialized devices used to deliver medication directly into a horse's lungs to help manage respiratory conditions. These devices are similar in design and function to inhalers used by humans, but they have been adapted to suit the...

Breathing is an automatic function that often goes unnoticed, until something goes wrong. Dyspnea, the term for difficult or labored breathing, is a serious clinical sign in horses. It is not a diagnosis itself but a symptom of underlying problems...

It's not unusual to see a small amount of clear, watery discharge coming from your horse's nose—especially after exercise, during cold weather, or when they've been around dust or pollen. Mild discharge is part of the body's natural defense system,...

Managing horses at shows requires a deep understanding of how unfamiliar environments can impact their health and performance. Horses undergo both physiological and behavioral changes in these settings, and without proper care, they may experience stress, illness, or injury. By...

Inflammatory Airway Disease (IAD) is a common, performance-limiting respiratory condition that affects horses of all breeds and disciplines, particularly young to middle-aged animals in training. Part of the equine asthma spectrum, IAD is characterized by airway inflammation and increased mucus...

Keeping horses safe during these activities is the number one priority, as is ensuring fair play for all competitors. As in human sports, there are multiple performance-enhancing substances which are controlled or banned by equestrian sports organizations. To that end,...

Gut sounds in horses are more than just background noise — they provide valuable clues about digestive function. These gastrointestinal sounds, known as borborygmi, reflect the activity of the digestive tract and can help caretakers detect early signs of gastrointestinal...

Keloids are an overgrowth of scar tissue that forms at the site of an injury in humans, extending beyond the original wound boundaries. They are dense, fibrous, and typically raised, smooth, and shiny in appearance. While horses do not develop...

Aural plaques in horses are a skin condition characterized by thick, pale, crusty patches that develop on the inner surface of the ears. These plaques may begin as small, raised bumps and can gradually merge into larger areas of raised,...

Flaring nostrils in horses are a powerful visual cue that should never be overlooked. Often dismissed as a sign of excitement, exertion, or even just a quirk of a particular horse’s personality, nostril flaring can provide critical insights into a...

Horses that are well-conditioned or physically fit are better able to perform their work. A fit horse has a reduced risk of injury and soreness and their increased strength allows them to work more effectively. Achieving peak performance in horses...

Squamous cell carcinoma (SCC) is one of the most common tumors affecting horses, originating in the squamous epithelial cells that form the outermost layer of the skin and line various internal surfaces. This condition can develop in a wide range...

Hoof capsule avulsion, or hoof degloving, is a traumatic injury that can severely impact a horse’s ability to move and function normally. The hoof plays a vital role in supporting the horse's weight, absorbing shock, and maintaining balance, which is...

Zoonotic diseases (zoonoses) are illnesses that are contagious between animals and humans. Horses can contract and transmit several different zoonotic diseases to humans, including rabies, anthrax, methicillin-resistant Staphylococcus aureus (MRSA), and ringworm. These pathogens represent three different types of microorganism...

Emerging equine research is the cornerstone of expanding our understanding of equine health, nutrition, management, and performance. This growing body of research provides valuable insights for veterinarians, equine professionals, and researchers seeking to apply evidence-based approaches in both clinical and...

Metronidazole (Flagyl®) is a commonly prescribed antibiotic in equine medicine, primarily used to treat bacterial infections in horses. It is particularly effective against clostridial infections, which can disrupt the delicate balance of gut bacteria and lead to severe gastrointestinal illness...

Reins are a standard and useful part of equestrian equipment, serving as the primary connection between a rider and their horse. Attached to the horse's bridle or bit, reins allow for clear communication through subtle movements of the rider’s hands,...

Supporting Limb Laminitis (SLL) is a serious condition that develops when a horse places excessive weight on one limb due to an injury or other issue in the opposite leg. Prolonged compensatory weight bearing disrupts blood flow within the hoof,...
