All horses will experience internal parasites at least one time in their life. Internal parasites are damaging to your horse’s health and well being. Signs that your horse may have worms are weight management, a distended belly, dull coat, low energy and signs of tail rubbing. If your horse is experiencing any of these symptoms consult a veterinarian. If these symptoms are left untreated, your horse may experience more severe problems such as digestion problems and colic.
Parasite prevention is simple when a rotation schedule is kept. Veterinarians recommend de-worming your horse every 6-8 weeks year round. Each time you use de-wormer, switch active ingredients using a rotation chart such as the below example. Rotating de-wormer ingredients allows all internal parasites to be treated in the course of a year, insuring that each type of parasite is effectively treated.
