Horses are commonly “quilled” when they investigate a porcupine on the ground, or kick or paw at one. As expected, quills are usually found in a horse’s muzzle or penetrating their lower limbs. The quills are not poisonous. There is also no need to clip their outward facing ends before removal. Suction is not involved in holding quills in the tissue. The quills are armed with barbs which allow them to migrate inward and cause them to be difficult and painful to remove.

WHAT TO DO

If there is a small number of quills, you can try removing them yourself. (See the related skill for more information.) If this effort becomes a struggle, stop, and call your vet. Quills or quill fragments left in the tissue can cause abscesses or migrate through the tissues to more distant sites, causing additional problems and infection.

WHAT YOUR VET DOES

Your vet may choose to sedate your horse prior to removal of the quills. This makes the procedure easier for everyone and less painful for your horse. In addition, your vet may choose to treat your horse with antibiotics and pain relievers and recommend further diagnostics if the quills penetrated the skin near vital structures (joints, tendon sheath, the eye).

What Not To Do

Do not struggle to get quills out and end up breaking them off under the skin.
