Allergies in Horse: Causes Preventions and Treatments (2022) - Silver Lining Herbs

Let’s Tame Horse Allergies!

Horses can have allergies the same as people can. An allergy is an abnormal reaction to allergens, or foreign substances, by an immune system that has become oversensitive. There are various ways to tame your horse allergies. Firstly, finding the cause is key in prevention and management. Horse allergies can show up in many different ways but the two most common is through the skin or respiratory system.

Skin Allergies and issues

The most common horse allergy is hives. Hives can appear around the neck and shoulders and then move over the rest of the body. Hives aren’t usually itchy but insect bites make for very itchy areas and you may notice your horse rubbing up against a structure to itch himself.


There are many causes of allergic skin reactions in horses. Allergy triggers like seasonal pollens, dust, mold – and bedding or maybe something topical that was used- can all show up as skin reactions. Vaccinations, and of course, insect bites are also very common causes of skin reactions.


If your horse is allergic to insect bites, the best way to prevent this is to try and get rid of the insects. Using sticky insect traps, sprays, and other insect control around your barn is helpful to keep insects off your horse. Our Bug Repel is helpful in keeping insects at bay around boarding facilities and off your horse.


Hives sometimes go away on their own. Sometimes even just a bath to rid your horse’s coat of pollens will do the trick. But, for more severe cases, your horse will need intervention. Helping your horse’s liver maintain normal histamine levels is key in the management of allergies. If you’re looking for something to support the normal detoxification process, assist the body in combating environmental pollutants, and clear up hives, look to our #27 Liver Support.

Respiratory Allergies

If you’ve noticed your horse coughing, sneezing, or wheezing without any nasal discharge, he may have a respiratory allergy.


Dusty, moldy hay or bedding, and pollens in pastures and in the air can cause horse allergies. Your horse’s immune system can be affected when they’re confined to a small indoor area. Breathing in dust and excrement odors in their surroundings can cause respiratory allergies to occur.

Prevention and Management

There are various ways respiratory horse allergies can be prevented and managed. Avoiding dusty feeds like hay and grains is a good start. Always check hay for irritants like mildew. Also, changing bedding to shavings or shredded paper can be helpful. Lastly, make sure your horse has plenty of fresh air. Further intervention may be needed if your horse still can’t stay healthy. Again, a natural herbal supplement such as our #27 Liver Support is beneficial in helping the liver to filter toxins and begin the process of flushing horse allergies from the body. Also, used in conjunction with our #22 Respiratory Support, your horse will be at an advantage by giving him a natural boost required for normal respiratory function. Lastly, introducing omega-3 fatty acids like hemp or flaxseed will help reduce inflammation caused by allergies. Our #44 Hemp Seed Coconut Oil is beneficial for both respiratory allergies as well as skin issues.

Bottom Line on Horse Allergies

Horse allergies can get worse over time when exposed repeatedly. By supporting horse allergies early on, you can minimize the effects they have on overall health. Supporting your horse allergies naturally, you will see the benefits many of our customers have experienced.
