Whether he is at a show, in his stall, or on pasture, your horse can get infected by internal parasites. Controlling internal parasites is essential for your horse’s health. These parasites can cause serious damages: they attach to the intestinal walls and consume blood, they can migrate to other organs through the intestines, and they can block arteries. Parasites are also responsible for colic, which can be dangerous for your horse. All horses carry parasites, so it is important to implement good sanitation practices and to maintain a regular deworming schedule to help control these parasites and keep your horse healthy.
