Horses July 16, 2008 Print Friendly and PDF

Pinworms (Oxyuris equi) can affect horse of all ages. The most noticeable clinical sign of pinworms is anal itching. Horses will be restless, may not eat properly, and a yellow/gray discharge may be noticed coming from the anus. Pinworms can be diagnosed by examining fecal matter for eggs.
