Skin
The skin is the largest organ in the body; it acts like a glove over your horse’s body providing warmth and protection. Secretions from the skin form a barrier to keep germs and water outside the body and bodily fluids inside. Breakdowns in this protective barrier cause hair loss, infections, and fluid losses. The appearance of the skin provides insight to the overall health of your horse. Common conditions affecting your horse’s skin include: allergies, bacterial infections, ringworm, internal and external parasitic infections, lacerations, sarcoids, and melanoma. Systemic conditions, such as autoimmune disorders, hormonal imbalances, or nutritional deficiencies, may display characteristic patterns in the skin to help your veterinarian diagnose the underlying problem.
