Not much can gross out a horse person. We happily pick out hoofs, observe the quality of manure, scrape bot eggs off our horses’ legs, and get a weird sense of satisfaction from an expressed abscess. But ticks… ticks are just nasty.

How to reduce the risk, recognize the symptoms, and take steps to manage an outbreak. Strangles is a highly contagious infection caused by the bacterium, Streptococcus equi (S. equi). It is not an airborne virus. Rather, the bacteria spreads through contact, which could be direct nose-to-nose between horses, or via contaminated surfaces or equipment such as shared halters, lead shanks, cross-ties, feed tubs, stall walls, fencing, clothing, hands, the hair coat from other barn pets, grooming tools, water buckets, and communal troughs.

Respiratory disease is one of the most important health concerns facing the horse industry, and accounts for one of the biggest reasons why horses miss training days (Rossdale et al., 1985). Equine asthma, also known as “heaves,” is one of the more troublesome small airway diseases which causes an elevated respiratory rate, chronic coughing and runny nose, and affected horses often find it difficult to exhale.

With exercise, the body temperature rises. This heat must be dissipated, or the horse will literally “cook”! The body cools itself through the evaporation of sweat, so sweating is especially important for the exercising horse. The sweat contains water and electrolytes, or salts. The main electrolytes are sodium, chloride, potassium, calcium, and magnesium. When the body loses water and electrolytes, various functions are compromised, and the health of the horse can be at risk. To ensure that your horse remains healthy, learn to effectively replace both the water and electrolytes — and the electrolytes must be replaced in balance with what has been lost.
