Deworming & Internal Parasites

The tapeworm, <em>Anoplocephala perfoliata</em>, gathers around the junction between the small and the large intestine in the cecum. This parasite is very common and most horses tolerate it well. Large tapeworm burdens can cause colic in the horse. Pyrantel (double dose) and praziquantel are effective drugs for treating tapeworms.
