Abdominal ultrasound is a valuable, non-invasive diagnostic tool that allows veterinarians to visualize the organs and soft tissues within a horse’s abdomen. Using high-frequency sound waves, the technique produces real-time images that can reveal both normal anatomy and subtle abnormalities....

Allergies are a common yet often misunderstood source of skin and respiratory problems in horses. Many owners recognize issues such as colic or lameness, while allergic reactions receive less attention despite causing significant disruption when symptoms become chronic, recurring, or...

Rectal examination remains one of the most valuable and informative diagnostic tools available to equine practitioners when evaluating gastrointestinal conditions. In cases of colic, it is often the single most informative procedure for identifying the underlying cause, determining the severity...

Joint disease and injury are common causes of lameness and poor performance in horses, particularly in athletic or young growing animals. Conditions such as osteochondritis dissecans (OCD), synovitis, and traumatic fractures of joint surfaces can significantly affect a horse’s comfort,...

Threadworms (Strongyloides westeri) are an equine intestinal parasite that primarily affects newborn foals, making them one of the earliest parasitic concerns in young horses. Transmission often occurs through the mare's milk, allowing larvae to establish in the foal's intestines within...

Bucking is an equine behavior that can be both thrilling and frightening for riders. It can be a playful leap in the pasture or a dangerous kick under saddle. Some horses buck to release energy or excitement, while others do...

Raised, red, or itchy swellings on a horse's skin are commonly described as hives, wheals, or urticaria. While the terminology may differ between veterinarians, owners, or practitioners, they all refer to the same physiological reaction. "Hives" is the common term...

The equine digestive system is a remarkably complex and sensitive network of organs, adapted to process a steady supply of forage around the clock. When its delicate balance is disrupted, the horse's ability to process and absorb nutrients is affected....

The equine gastrointestinal system is one of the most complex parts of a horse’s body. Designed for nearly constant grazing, a horse’s digestive tract depends on a steady flow of forage, water, and beneficial microbes to function properly. When this...

Cooling down a horse after exercise is a vital part of responsible equine care, ensuring their body transitions safely back to its normal state. This process allows the horse’s temperature, heart rate, and respiration to stabilize after exertion, supporting overall...

Neurologic disease in horses often presents a diagnostic challenge, as clinical signs can be vague or difficult to narrow down to one disease. A valuable tool available to veterinarians handling neurologic cases is cerebrospinal fluid (CSF) analysis. By providing a...

Fungal diseases in horses represent a diverse group of conditions that can affect the skin, respiratory tract, eyes, and internal organs. While less common than bacterial or viral infections, fungal infections are often more insidious and challenging to diagnose. Because...

Abdominal disease is a common and sometimes life-threatening problem in horses, with colic being one of the most frequent emergencies encountered in equine practice. One valuable tool in the diagnostic process for colic cases is abdominocentesis, also known as a...

The equine heart is a remarkable organ, designed to support athletic performance, endurance, and overall health. However, like any system, it can be affected by disease or structural abnormalities that compromise its function. Detecting heart problems in horses can be...

Sleep is a fundamental part of equine life, yet it remains one of the least understood aspects of horse behavior. Every horse depends on rest to restore the body and mind, and equine sleep is quite different from what we...

An ophthalmic examination involves more than simply looking at the surface of the eye. A complete assessment evaluates the cornea, lens, anterior and posterior chambers, tear production, ocular pressure, and reflexes. Special diagnostic tools, such as fluorescein dye, Schirmer tear...

Hay is the cornerstone of most equine diets, providing the fiber necessary for gut motility and a healthy microbiome, along with essential nutrients to support body condition, energy levels, and overall well-being. However, when hay becomes moldy, its value as...

Lens luxation is an uncommon but serious eye condition in horses. It occurs when the lens — the clear, flexible structure inside the eye that helps focus light — slips out of its normal position. This displacement can cause pain,...

The horse's eye is large, delicate, and vital for navigating its environment. Its prominent position and limited natural protection make it especially vulnerable to injury. Eye prolapse, also called proptosis, is uncommon but serious, occurring when the eyeball is displaced....

Swollen sheath in horses is a common condition that owners may notice when the area around the penis appears enlarged or puffy. In many cases, sheath swelling is mild and temporary, often linked to inactivity, seasonal changes, or fluid retention...

Viral infections are among the most common health challenges faced by horses, ranging from mild, self-limiting illnesses to severe, life-threatening diseases that spread rapidly through equine populations. Because many different viruses can affect horses, recognizing and correctly diagnosing these infections...

A horse’s eyes are highly specialized organs that play an essential role in survival, communication, and performance. The equine eye is large and laterally placed, offering a wide field of vision that allows horses to detect threats in their environment....

Electrocardiography (ECG) is one of the most important tools veterinarians use to evaluate equine heart health. While stethoscopes remain invaluable for identifying murmurs and abnormal rhythms during a physical exam, an ECG provides a more precise and objective way to...

The nervous system plays a vital role in every aspect of a horse's health and performance, from balance and coordination to sensory perception and behavior. When this system is interrupted, the signs can be subtle or dramatic, and distinguishing neurologic...

Urinalysis is a simple yet powerful diagnostic tool that can provide valuable insights into a horse’s overall health. By examining the appearance and composition of urine, veterinarians can assess kidney function, hydration status, and the presence of certain toxins. Although...

Necropsy, also known as an autopsy or post-mortem examination, is a vital diagnostic tool in equine veterinary medicine. When a horse dies unexpectedly or under unclear circumstances, performing a necropsy can provide critical insights into the cause of death. Necropsy...

Radiographs, commonly known as X-rays, are one of the most valuable diagnostic tools in equine veterinary medicine. They allow veterinarians to examine the internal structures of the horse—primarily bones and joints—without the need for surgery or invasive procedures. Whether evaluating...

Gastroscopy is a valuable diagnostic tool that allows veterinarians to directly visualize the inside of a horse's upper digestive tract. This minimally invasive procedure uses a specialized flexible camera, called a gastroscope, to identify abnormalities that cannot be detected through...

Autologous Protein Solution (APS) is a biologic therapy that has emerged as an innovative treatment for managing joint and soft tissue injuries in horses. This biologic therapy uses the horse's own blood to create a concentrated solution of anti-inflammatory proteins...

Sports recovery is an important aspect of equine management, focusing on the horse’s well-being following periods of exercise. During physical exertion, a horse’s muscles, tissues, and cellular structures undergo stress. When well-managed, this leads to adaptations that strengthen and condition...
