Lungworms (Dictyocaulus arnfieldi)

lungwormLifecycle: Lungworm larvae go through intestinal walls into the circulatory system where they are carried to the lungs and mature. Eggs pass through the horse's system in manure.

How It Gets Into Your Horse: Lungworm larvae are swallowed as your horse eats infected grass.

Dangers If Left Untreated: Lungworm larvae irritate the small air sacs in the lungs, called the bronchioles, which can cause the horse to have a severe cough, difficulty breathing and loss of aphorseite.

Older horses usually develop a resistance to lungworms, but foals can die from an infection because they have less immunity to the parasites.
