Equine lameness is an indication of a structural or functional disorder, in one or more limbs or the spine, evident while the horse is standing or in movement. It can range from very mild discomfort, which may only be perceived by the owner or trainer as a decrease in level of performance, to severe pain in which the horse is unwilling to bear weight on the limb. As one of the most common and most expensive medical problems in horses, lameness represents a large concern to the equine industry as well as to individual horse owners.

When things just don’t feel right, you may experience a hollow feeling in the pit of your stomach, or you might actually manifest physical symptoms such as gastric distress, perspiration, or muscle tremors. In humans and in horses, stress can create a multitude of psychological reactions ranging from mild anxiety to debilitating near panic and severe depression, and reduced immune response which can invite illness. Long term stress can produce ulcers, musculoskeletal disorders, heart irregularities, and create a host of psychological vices.

Equine laminitis has been with us for a long, long time. Fortunately, in the last 10 to 20 years there have been great strides in understanding the causes of this terrible condition. Laminitis is now regarded as a syndrome that occurs secondary to something else, rather than a discreet disease all in itself. This has allowed much more focused research and effort in treating the cause rather than treating just the symptoms that occur in the hoof. It doesn’t matter how great the trim is, or what shoes are used, or how deep the bedding. If initiating causes such as EMS (Equine Metabolic Syndrome – see Equine Metabolic Syndrome & Equine Cushing’s Disease, Early Summer 2018 issue of Canadian Horse Journal) or PPID (Cushing’s disorder) are not addressed, the laminitis and the pain will continue.

A study into the causes of severe equine asthma (sEA) has revealed associations with over 113 substances, including latex found in artificial surfaces. Lead researcher Sam White found that natural rubber latex was among “the most surprising and significant” of several new allergens present in the dust horses breathe.
