How to apply NT-Dry?

First and foremost be "aggressive" with the product. During active treatment, use the powder liberally. The goal of NT-Dry is to attack thrush while simultaneously wicking the excess moisture from the bacteria breeding area. The specialized clays 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 crevices in the frog and in the central sulcus heel crack. Remember, there should not be a crack in the sulcus in the first place- bacteria created it. The crack is warm and moist inside... and as long as it exists, bacteria will return. Regular use of NT-Dry 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.

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

3. Using the edge of your hoof pick open the sulcus and make sure to push NT-dry powder into the openings. Fill the sulcus crack. If this is a severe case of thrush you will notice NT-dry immediately wicking the moisture.

4. Repeat daily. In most cases, after 4-6 days you will no longer notice any moisture. The frogs will have firmed, and the horse's tenderness will have decreased. After 6-7 days it is normal to experience a healthy, rejuvenating, shedding of the frog and heel bulb area. (NOTE: NT-dry will definitely 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.

5. 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, so we want to open the area up to as much air as possible.

6. 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.

7. IMPORTANT NOTE: We can't emphasize this enough..... An open sulcus is always susceptible to a thrush re-invasion. We recommend regular NT-Dry dusting until the sulcus has healed and closed. Depending on the thrush severity, this healing can take 14-40 days.

8. Once the thrush is gone and the sulcus is closed, use NT-dry 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 known problems, rather than chasing them.


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 tissue is letting go to make room.

2. With 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." 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.
