Under the Sun: How to protect your Horse from Sun Damage and Sunburn

Posted on 14 June 2018 by Kim

How to protect your horse from the Sun

After the ravages of winter, the sun is welcome sight to both owners and their horses. The sun makes us and them feel good. It’s important for the production of Vitamin D which helps ensure proper functioning of the bones, joints and muscles. However, getting too much sun can create some problems for your horse as well.

Common Sun Problems

Sunburn

Sunburn occurs most often on horses with light-coloured coats, such as greys, skew or piebalds. Horses with white blazes or pink noses are highly prone to it also.  Without protection, sun exposure to these areas can lead to sunburn, just like you may have experienced – the skin turns red, may blister or peel and is sensitive to the touch. This usually occurs on the muzzle and possibly around the eyes. Some horses can sunburn on other areas as well.

Photosensitisation

The greatest concern regarding sun exposure is “photosensitisation”. This is a condition that causes skin sensitivity to ultraviolet (UV) rays. It’s primarily affects horses, sheep and cattle but other species may also be susceptible.

The condition can be divided into two categories - primary and secondary:

  • Primary photosensitisation occurs due to the ingestion of lush green plants containing “photodynamic” agents, such as St John's Wort or clover
  • Secondary photosensitisation is the most common type of photosensitivity seen in animals and occurs due to liver or bile duct damage. It’s most often because of ingestion of hepatotoxic plants such as Senecio Jacobea more commonly known to horse owners as ragwort.

Coat Fading

Sun exposure can “bleach” the colour of some horses’ coats. This is more common for black, dark brown and dark bay coats but it can actually happen to coats of all colours. The most commonly affected areas are the saddle area and around the face which is where sweat tends to accumulate. Although coat fading isn’t really a health problem, you do want your horse to look and feel his best.

Preventing Sun Damage

Although you can’t keep your horse stabled 24/7, there are a few things that you can do to help minimize the chances of your horse getting sunburned.

Time Management

Time management is a key component to keeping your horse safe from sun injuries. Start by regulating the time your horse is out in the bright sunlight. Plan your horse’s outdoor hours so that they coincide with times of less sun exposure, such as early morning, evening or even overnight.

Environmental Management

If possible ensure that there are shaded areas in his field, so that your horse can take breaks from the sun. Check your fields for any plants that can cause photosensitisation and remove or at least fence the areas or plants off from access.

Sunscreen

Apply sunscreen to the muzzle and any white markings on your horse. Use a high-SPF sunscreen and remember that it requires regular reapplication for complete coverage. Don’t be stingy — put on a thick layer. This will help when your horse grazes in the dew-covered grass or dunks his muzzle in the drinking trough.

Coat Protection

Consider using fly sprays and/or coat conditioners that include UV protectants and apply regularly.

If you can’t manage your horse’s time in the sun and you have limited or no shade in your field, consider using a fly rug and a face mask for additional protection.

Treating a Sunburn

If your horse gets mild sunburn on his muzzle or face, apply a soothing ointment such as aloe. Then put a heavy coating of sunscreen over that to minimize further damage. Make sure your horse has access to plenty of fresh, clean water; hydration helps heal damaged skin. If the symptoms are severe or don’t resolve, consult your vet.
