Skin is Sloughing Off, Anywhere on Body


Skin dies off as a result of direct injury to the cells or loss of blood supply which provides nourishment. The exact cause of skin sloughing could include trauma, loss of blood supply, damage by infectious agents, severe allergy, poisonous snake and spider bites, and many others.

Any sort of skin trauma (especially bites or kicks from another horse) may not initially result in a visible problem other than a slight swelling and what appears to be a scrape. However the skin may actually be more severely damaged, and it may begin to dry up and slough off in a few days.

Sometimes only the superficial layer of skin peels off. In other cases, the damage is full skin thickness, resulting in an open wound underneath. In partial thickness sloughing, there will be thickening of the underlying skin and generally hair will re-grow in the area. For full thickness wounds, scarring may result.

What To Do

You can gently remove any loose, obviously dead skin but do not aggressively pull away skin as you may remove skin that is still viable and might contribute to healing. Consider the amount of swelling and presence of any discharge. If the injury is on a limb, consider whether the horse is lame. Contact your vet with your findings and concerns.

your vet's role

Your vet will look at the distribution of the sloughing skin and try to determine the underlying cause and the best treatment plan.
Questions Your Vet Might Ask:
  • Does your horse seem normal otherwise?
  • Does the problem seem confined to white haired/pink skinned areas?
  • Does it appear that this was caused by trauma?
  • Where is the skin peeling?
  • Is the horse stabled with other horses?
  • What are the results of the Whole Horse Exam (WHE)?
