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.

Like humans, horses can be hypersensitive to a wide variety of allergen triggers including insect bites, pollens, dust and molds, chemicals in crop sprays, hay dust, stall bedding materials, wool (sometimes in saddle pad and blanket products), grooming sprays, shampoos, synthetic materials such as neoprene found in boots and pads, medications, supplements, and some ingredients in feed pellets.

Horses require access to free choice, clean water at all times and in all seasons, and will drink an average of 30 litres of water per day. Many horses’ diets see an increase in dry feed matter, like hay, during the winter months. As a horse requires three litres of water for every kilogram of dry matter they eat, although horses drink less in cold weather, adequate water consumption remains a priority.

Horse owners are routinely putting rugs (blankets) on their horses all year round. However new research suggests that certain types of rug could be causing them to overheat. It has become routine (and even fashionable) for many domestic horses to be rugged all year round – in fly-sheets, all-weather turnouts, stable rugs, fleeces or perhaps even a onesie. Rugs can be useful in protecting horses from biting insects and in adverse weather conditions; however, until now there have been very few studies on rugging at all and none on the effect of different types of rugs on a horse’s body temperature.
