01THE SCIENCE OF DRYNESS

It's the first DRY way to treat rain rot because rain rot hates dryness

Rain rot is bacterial, caused by Dermatophilus congolensis, which needs trapped moisture against the skin to activate. Sprays and medicated shampoos add more water to the problem. Coat Defense removes removes it quickly and safely, starving the bacteria of their food source.

Sodium bicarbonate at just 5 g/L inhibited 80% of skin fungal isolates in laboratory testing (Letscher-Bru et al., Mycopathologia, 2012).

02Clean ingredient formula

One product is the solution for multiple skin troubles

Safe and fast acting non-toxic ingredients, leaves skin microbiome and nourishing and natural skin oils intact both essential for skin wellness and a soft, shiny coat. Use as part of grooming routine to prevent skin funk from taking hold in all seasons throughout the year.

03NO STEROIDS NEEDED

Soothes sweet itch without steroids and without the laminitis risk

Up to 60% of horses in some regions suffer from sweet itch the most common pruritic disease of horses worldwide. Most owners are stuck choosing between dexamethasone (laminitis risk) and a $300 blanket. There's a third option.

04Cost comparison

Saves $300+ vs. sweet itch rugs and actually heals the skin

No chlorhexidine. No steroids. No mineral oil. No piperonyl butoxide. Just five readable ingredients each backed by peer-reviewed research that work together to dry, heal, and protect horse skin.

05Any season

No bathing. No re-spraying every 6 hours.

Cold weather? You can't bathe. Show day? You can't drip oil. Coat Defense works in any season, any temperature sprinkle, rub in, walk away.

06Show-ring legal

USEF & FEI compliant legal in the show ring (unlike steroids)

Pros use it under tack to prevent rubs. Dexamethasone, triamcinolone, and many fly-spray residues are restricted or banned in competition. Coat Defense isn't and it's safe for the rest of the barn too.

07TRUSTED BY 100,000+

100,000+ horses already switched. And it works on your dog too.

The same non toxic formula (with organic cedarwood oil in for organic peppermint oil) works on dogs, cats, and barnyard animals. Try it on one stubborn case you'll keep buying it for everything else.

Horse Shampoo

BREAKS THE CYCLE: Our Horse Shampoo doesn’t strip skin down to a vulnerable state like other chemical laden shampoos. By gently cleansing with ONLY beneficial ingredients, skin is left with nourishing and natural skin oils still intact, leaving skin supple and the coat soft and shiny making dull coats and dry skin a thing of the past. Finally, a shampoo that is soothing, moisturizing and healing.

Directions

Daily Preventative Powder

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 lighten the coat. We believe it has to do with the chemistry of a horse’s sweat and/or sunlight exposure mixed with the ingredients in our formula. If this concerns you, please use at your own risk.

Trouble Spot Drying Paste

Prior to application, gently clean any dirt or debris from treatment area. DO NOT pick off any existing scabs. Allow scabs to fall off on their own with Paste.
Using fingertips, scoop paste from container and spread thickly over treatment area. Spread as if covering bread with peanut butter, spread to surrounding areas and down to the skin. Do not rub in.
Let paste dry to a near white shell and leave on for several days.
Reapply as necessary until skin is fully healed.
For open wounds, to achieve better adhesion of the paste, first dry oozing by patting with a clean cloth and/or applying COAT DEFENSE® daily Preventative Powder.
Paste is also effective if thinned out with water or witch hazel. A more paint like layer of the paste provides an effective barrier between exposed skin (ears, bellies, etc.) and biting insects.
To remove, please wet first. Paste become abrasive when it is dry.
Use COAT DEFENSE® daily Preventative Powder to prevent future flare-ups. It’s a game changer for prevention!

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

Horse Shampoo

A little goes a long way!

You can use this shampoo directly out of the bottle, just start with a small amount and the lathering will be surprising.

Should you want to dilute before using, the following is what most of our horse customers are following:

8-ounce bottle will make 32 ounces of shampoo.

Enjoy and remember: The first ingredient is Aloe (not water) nature’s most nourishing and therapeutic ingredient for the skin and coat.

This is great stuff!

I got this because my horse has thin hair and sensitive skin and is very prone to sweet itch. I’ve seen major improvements in his hair growth where there were patches missing from rubbing. I’ve also seen his bumps/hives go down significantly. These 2 photos are 3 weeks apart. I highly recommend!

Completely healed in 1 days and hair regrew. This stuff is seriously amazing and will keep it in my tack room at all times and you should too! Like miracle stuff!

Amazon QueenVerified Purchase

My friends say she’s always so white. It’s all coat defense.

My friends say I should’ve bought stock in this company. I use so much coat defense. I have 2 gray mares and this keeps them looking white naturally. I love using it as a grooming aid. My horses look amazing. It did a fantastic job clearing up some fungus too.

Frequently Asked Questions

How fast does Coat Defense work on rain rot?

Most horses see noticeable improvement in 1–3 days. Severely immune-compromised horses (Cushing’s, on antibiotics or steroids) may take 1–2 weeks. Apply daily and leave on, do not pick scabs; let them slough naturally.

Is rain rot fungal or bacterial, and will antifungal products work?

Rain rot is bacterial, caused by Dermatophilus congolensis, which behaves like a fungus but isn’t one. Antifungal-only treatments don’t kill it. Coat Defense works because it dries up the moisture D. congolensis needs to reproduce, kills the bacterium with alkaline pH, and supports skin healing, the only mechanism that addresses the root cause.

Will Coat Defense replace my sweet itch rug?

Many owners use both, but the powder treats the inflamed, broken skin a rug can’t fix. If your horse has severe Culicoides hypersensitivity, a fly mask + rug + powder layered approach works best. For mild-to-moderate cases, the powder alone has eliminated symptoms in hundreds of testimonials.

Is it safe with steroids, antibiotics, or other medicated shampoos?

Yes, but discontinue chlorhexidine, sodium lauryl sulfate, coal tar, and salicylic acid shampoos for 3–5 days before applying, and patch-test first.

Can it be used in winter?

Yes, that’s a key advantage. It dries sweat without bathing, so your horse won’t freeze. It’s specifically marketed as a cold-weather alternative to medicated baths.

Is it legal at USEF / FEI shows?

Yes. Coat Defense Daily Preventative Powder is USEF and FEI compliant. Many pros use it under tack to prevent rubs.

Will it lighten my dark horse's coat?

In rare cases, yes, regular use combined with sweat chemistry plus sunlight on alkaline ingredients may lighten the coat. Patch-test on dark coats first.

Powder vs. paste, which one do I need?

Powder = prevention + early-stage and mild active cases. Paste = active wounds, scratches, broken skin. The brand recommends Powder daily and Paste for trouble spots.

Can I use it on my dog or myself?

Yes. The equine formula uses peppermint EO; the canine/feline and human formulas swap in cedarwood or eucalyptus/clove. Same core blend, alkaline, drying, antimicrobial.
