An overabundance of fat along the top of the neckline, otherwise known as cresty neck, is an indicator of metabolic problems in your horse. In fact, researchers believe this type of regional fat deposit (nuchal crest adiposity) is a strong...

A healthy equine gastrointestinal microbiome contains a diverse range of beneficial microbes that support digestion, immune function and nutrient synthesis. Because horses are hindgut fermenters, a healthy microbiome is essential for overall wellness. Dysbiosis is defined as a microbial population...

Arthritis is defined as inflammation in one or more joints, which leads to pain and stiffness. The condition is degenerative, meaning it cannot be reversed in most cases and tends to worsen over time. However, there are steps that horse...

What is the best way to support a horse affected by a ligament injury? Unfortunately, due to the nature of many equine disciplines, a horse’s ligaments are prone to injury. In fact, ligament sprains (along with tendon injuries) are the...

This painful condition commonly leads to debilitating lameness. In horses with DSLD, the suspensory ligament progressively...

Painful hoof abscesses in horses develop when bacterial and fungal organisms enter the hoof structure through a wound or opening and cause infection in the inner tissues. The invading microorganisms and the ensuing immune response generate purulent exudate (pus) which...

Founder is a common cause of lameness in horses. It involves damage to the laminar connection between the hoof wall and the coffin bone. This often leads to rotation and/or sinking of the coffin bone which causes severe pain and...
