Like other mammals, horses are subject to parasitic infestations. The list of worms affecting horses is long, but common types include large roundworms, pinworms, tapeworms, and even non-worm parasites like botflies.
New and low infections may not cause immediate noticeable problems in horses. However, worms can quickly progress and damage your horse’s coat, condition, and overall health. Colic is one of the major effects of parasites.
