Horse Muzzle Skin Problems

The skin of a horse's muzzle is less protected than other areas of the body. With less hair covering and the presence of delicate mucous membranes, this area can develop specific problems.

  1. Photosensitization

    • Photosensitization is a reaction to UV light which can seem like sunburn at first. It appears primarily on white hair areas with pink skin. It can be caused by either ingesting plants such as St. John's Wort or can be a symptom of liver problems.

    Hives

    • Hives are a symptom of an allergic reaction, resulting in bumps on the muzzle. They can be caused by a number of irritants like feed, insect bites and medication.

    Pemphigus foliaceous

    • Pemphigus foliaceous manifests as tiny blisters and can affect the mucous membranes. It is a serious, auto-immune disorder in which the immune system targets the mucous membranes.

    Warts

    • Viral papillomatosis, or warts, are small viral bumps that may occur on the lips. They are common in horses younger than 1 year old. They tend to heal on their own but can also be removed by a veterinarian if needed.

    Sarcoids

    • Sarcoids are a common skin tumor in horses, a wart-like or raw area commonly found on the ears and lips. They can be spread by tack, insect bites, biting or rubbing. They can be removed surgically or treated with a topical remedy.

    Ringworm

    • A fungal infection which is easily spread from horse to horse, ringworm can look like hives or appear as a scaly patch of skin. While it can be treated topically to shorten the course of the cycle, typically an untreated horse will heal on its own in 1 to 3 months.
