Prevent & Treat with the Best Defense - COAT DEFENSE®

The dry barrier solution to equine skin & coat problems


COAT DEFENSE® daily PREVENTATIVE POWDER is a natural, safe and effective solution for preventing and treating equine skin issues such as rain rot, itch and odor. It is revolutionary because it prevents chafing, fungus and pathogenic microbes from taking up residence on your horse. It's a game changer because it soothes and calms allergies, hives and sweet itch without harsh medications. It is effective for drying sweat and moisture quickly, saving you time and preventing your horse from freezing when temperatures drop. In addition to alleviating skin problems, it can be used between baths as a dry shampoo.  


  • Eliminates and prevents rain rot, fungus, thrush, scratches and odor.
  • Soothes itchy and inflamed skin caused by insect bites, allergies, hives or sweet itch.
  • Use to save time drying moisture and sweat in cold months.
  • Prevent chafing, rubs, fungus and bacteria under equipment including boots, Rx boots, blankets and saddle pads.
  • As a dry bath to protect and retain natural shine.
  • HUMANS love it too:
    • Dries and dissipates odor on contact anywhere on the body, also in helmets, boots, blankets and equipment.
    • As a dry shampoo
  • Effective for dogs and other barnyard animals.
  • Sprinkle powder directly onto desired area, massaging it in a circular motion down to the skin.
  • If using as a remedy, leave on continuously, applying more as it wears off until completely healed.
  • In hard to reach areas, such as legs or under belly, pour powder into palm of hand and place directly onto desired area down to skin.
  • If using as a preventative or under equipment, apply generously and massage down to the skin and leave on.

For dark horses:  In very rare instances, regular use of COAT DEFENSE® daily PREVENTATIVE POWDER may magnify the lightening effect of the sunlight and sweat. For our peace of mind, please test in a small area first.

    Works like magic!

    This product works very well against sweet itch. I saw results after only one time use, and it kept the issue away ever since. I purchased the refill bag after used the 8 oz size. Also got the shampoo and loving it as well! Recommend it to a friend who also got great result. Thank you for making such wonderful products!

    Great product!

    With this crazy weather this summer my three horses developed a little rain rot. I tried sprays & ointments. Nothing seemed to get rid of it entirely. When I seen this at Big Dee’s, I thought about giving a powder a shot. I liked that it was non toxic, talc free. Within days the rain rot was gone. Horses don’t mind the powder and they are getting relief. Started using it on my dog that has a cast on her leg and was getting chafing from the cast. Took the redness away and she doesn’t mind the powder. I love this stuff so much that I purchased the refill bag and also the deodorant for myself.

    Love this!

    I have a Cremello gelding with super sensitive skin. I sprinkle this on him under his fly sheet. I love the ingredients. We are both so over chemicals after a very wet summer and lots of bugs

    For the first time ever, (11 years), my gelding has sweet itch and summer sores. I recently broke my leg and was unable to give him the care he is used to receiving and this happened to my poor boy. Now that I am on my feet and can care for him, I use both the powder and the paste twice a day. He has sores from rubbing and scratching from nose to tail. The powder and paste both stop the bleeding, protect, and heal quickly and give him relief. I only wish that it was odorless because he will let me touch his face with my hands unless I have the powder or paste on them. He knows because of the minty smell.

    Daily Use of Coat Defense Powder

    We live in the Gulf Coast region of the Southeastern U.S. where humidity, sun, and insects take their toll on our equines. June and July have been extremely wet as well, with heat indexes this weekend reaching 105-110 degrees. I use Coat Defense powder on my yearling mustang to help prevent/heal rain rot and greasy heel, in conjunction with the drying paste on areas that are likely to sunburn (my spotted donkey’s blaze face, top of her ****, etc.). Both products are excellent!
