The Best Thing for Thrush
Treat Scratches and Rainrot!
Usage - and treating thrush.
Below you will find detailed usage-tips for NO THRUSH - AND "What to expect"

Many NO THRUSH customers use the product in varying ways, for varying equine and pet issues. Below is what we believe is the best, most effecient treatment method. If you use it differently and have good results, please let us know. We will add your discoveries below.

NO THRUSH ® application / usage suggestions:
(Be sure to watch the video at the bottom of this page.

First and foremost – be "aggressive" with the product. During active treatment, use the powder liberally. The goal of NO THRUSH® is to attack thrush while simultaneously wicking the excess moisture from the bacteria breeding area. The specialized clays dry and absorb far more that their weight in moisture, so be sure to get enough into the infected area to extract all that black goo from the crevises in the frog and in the central sulcus heel crack. Remember, there should not be a crack in the sulcus in the first place. It was created by bacteria. It is warm and moist inside... and as long as it exists, bacteria will return. Regular use of NT will provide a healthy healing environment (without burning the tissue!) and allow the sulcus to re-grow properly.

Sulcus Crack + Soft Heel = Thrush

1. Using your hoofpick and hoof brush, remove all debris, manure and mud. DO NOT WASH. Thrush creates its own moisture, so adding more is counter-productive.

2A. Once per day dust No Thrush ® on the frog, heel bulbs, around the horse-shoe and into any whiteline grooves, and into the sulcus crack. NT is not caustic so there is no danger of overuse. (For severe cases, NT can be used twice daily for the first few days of treatment, which will extract the black goo and moisture at rapid pace.) 

2B. Using the edge of your hoofpick open the sulcus (the heel crack) and make sure to push NT powder into the openings. Fill the sulcus crack. – You will notice NT immediately wicking the moisture, absorbing it, and drawing it out of the nooks and crannies. (NOTE: A little puff on top of the sulcus will not be enough powder.. It is essentual to get plenty of powder "inside" the sulcus.)   

3. Repeat daily. In most cases, after 4-6 days you will no longer notice any moisture/mess. The frogs will have firmed, and the horse’s tenderness will have decreased. After 6-7 days it is normal to begin experiencing a healthy, rejuvenating shedding of the frog and heel bulb area. (NOTE: NT will definately work in rainy, damp environments. However it is best to keep your horse out of deep puddles during initial treatment. Many clients prefer to dust during feeding time. 

4. Whenever you see excessive necrotic tissue flaking away from the frog and sulcus cut it away with your hoof knife (or have your farrier/trimmer do this whenever possible). Thrush bacteria hides in air-free environments…. Thus, we don't want to give it skin tags to hide under and begin breeding again. 

5. Every horse and thrush-case is different. You must be the judge of when it is appropriate to slow down the application process. In most typical cases this will occur at 6-7 days. Extreme cases could take up to 14 days, depending on how invasive the thrush has become. Remember- Thrush does not appear overnight! It has been brewing inside the foot for weeks or months before we actually see it.

6. IMPORTANT NOTE: We can't emphasize this enough..... An open sulcus is always susceptible to a thrush re-invasion. We recommend regular NO THRUSH ® dusting of every 2-3 days until the sulcus has healed and closed. Depending on the thrush severity, this healing can take 2-6 weeks.

7. Once the thrush is gone and the sulcus is closed, use NT in a preventative/maintenance program (every 5-10 days recommended) to keep the bacteria at bay: We believe it is better to stay ahead of the thrush cycle, instead of forever chasing it. 


Regularly dust hoof boots with NO THRUSH to combat excessive bacteria buildup and odors.

Use on scratches. Do Not Wash the leg. Instead, wipe away any mud with a soft towel but do not remove the scabs. Thoroughly dust area and use soft brush to distribute the powder into the coat of the infected area. Again... do not remove the scabs - let these fall off naturally. Repeat daily and then use as prevention aid. You should notice healing begin in 3-4 days. Extreme, long-term cases may take several weeks to fully heal, but typical cases clear up in 8-10 days. 

Use on Rain rot, coat fungus. Do Not Wash. Dust affected area (rub the powder thoroughly into the coat. Repeat once daily for 4-7 days. Use as maintenance while the coat regenerates.

Use NT CANINE on Dog Hot Spots. Follow the same treatment for Rain Rot above. You should notice a significant reduction in itching/scratching in the first 2-3 days. Continue dusting every few days until the coat is regrown. If the hot spot has been a recurring problem, treat once a week in a maintenance program to stay ahead of the problem. 


1. Expect a frog/heel shedding to begin after a week or so. This is a good, healthy sign! It means that the healthy tissue is emerging from underneath - and that the exterior, necrotic tissue is letting go to make room. 

2. With extreme sulcus thrush and frog disease you might see the top edge of the frog begin to peel away. Again, this is a great sign. This means that the inside of the frog had been significantly diseased and literally "hanging on by a thread." After NO THRUSH attacks the bacteria and absorbs the breeding grounds from the depths of the frog, the healthy tissue is allowed to grow from the inside out, and outer layer is allowed to shead.  This sheading may expose even deeper-seated areas of thrush, (places that might otherwise never be found) so continue to dust regularly until the frog has re-grown.


Treat thrush fast and easy. Just "Dust-on"
