I have read a few of your answers to e-mails and I have a question
about one of our horses. He is a stallion and he has a bad case on thrush
in his feet. It has chewed away at his frogs, so now they are completely
gone. What can we do to stop this and prevent it from happening again?
Thank you for your help. Bryce
Although thrush most commonly affects the grooves on either side of the frog (collateral
sulci) and in the center of the frog (central sulcus), it can invade the white
line and even areas of the sole. Here are a few facts to help you prevent
and get rid of thrush:
The bad new is, thrush bacteria are almost always present in the soil, just waiting
for the opportunity to move into the warm, dark, moist environment found in the
bottom of your horse's hoof.
The good new is, thrush is anaerobic, the bacteria don't survive in the presence
of air. So, the best way to avoid thrush is to keep your horse's feet clean
and dry so air can reach the tissues. But, as every horseowner knows, this
is easier said than done. Horses, especially those in confinement, often
dont have a dry place to stand, and even if they do, they often choose to
stand in wet bedding, manure, or mud at least part of the time. One of the
consequences of wet footing is thrush.
DO NOT apply bleach or hydrogen peroxide to a horses feet. These so-called
treatments will burn the healthy tissues of the frog and actually
Commercial thrush remedies vary in effectiveness, and ease of use, and can cost
up to $12 per ounce! Many products in squirt bottles are very messy to apply.
Some contain fungicides and bactericides (like gentian violet and copper naphthenate)
which are also staining agents. The purple or green color of the liquid
lets you see without a doubt where the product is being applied but also stains
everything it touches, including your clothes and hands and your horses
hair - and it is difficult, if not impossible, to remove. Other products
smell worse than the thrush itself (which is pretty bad!).
Sugardine is a home-made thrush remedy thats effective, easy to use, doesnt
stain, and has no bad odor. Plus, it only costs around $0.34/oz to make.
Sugardine has been used for years in human medicine to treat wounds and burns.
It reduces edema (swelling), nourishes surface cells and speeds healing.
To make sugardine, mix a povidone-iodine product - such as Betadine scrub, solution,
or ointment - with white table sugar to form a thin paste. Generic povidone-iodine
is often half the price of Betadine and is basically the same product.
To treat thrush, first trim loose and overgrown flaps of frog so air and medication
can reached the affected tissues. If youre not comfortable doing this,
ask your farrier or vet for help. Wash the hoof thoroughly with mild soap,
such as Betadine scrub, and plenty of warm water. Pat the hoof dry with
a cloth and apply sugardine deep into the clefts of the frog using a small brush,
such as an acid brush. An acid brush has short flat black bristles and a
tubular metal handle 6" long and is available at hardware stores for about
25 cents. The sugar will settle to the bottom of the container, so youll
need to stir sugardine thoroughly before each use.
Apply sugardine daily until the thrush is gone and keep the horses feet
as clean and dry as you can to prevent reoccurrence.
