Thrush in Horses

A “Thrushy Hoof” Isn’t a Healthy Hoof

My horse’s hooves are healthy. They just have a little bit of Thrush,” is a statement we hear too often from individuals battling thrush. Unfortunately, Thrush in horses has become such a common occurrence that many horse owners do not give it the levity it deserves. It is important that the horse owner understands, a hoof with any amount of Thrush is NOT a healthy hoof!

In short, Thrush in horses is a microbial invasion of the sulci, or the grooves surrounding the frog, that often leads to an infection in the tissue of the frog. In previous blogs we have discussed what causes Thrush. Your horse’s hooves can be predisposed to Thrush by:

  • High humidity and wet environments
  • Stalls containing urine, excrement and excess moisture
  • Lack of oxygen to the frog area due to packed debris
  • Poor hoof maintenance
  • Improper trimming

Exposing your horse to one or more of these factors can create conditions conducive for Thrush development. Once Thrush has established, address it immediately. Even mild Thrush can become serious quickly.

Thrush, The Hoof and The Horse Owner

The first steps in preventing or treating Thrush in horses is to provide the necessary elements to promote the best quality hoof possible.

The health of your horse’s hooves is not your farrier’s responsibility alone. Treating and preventing Thrush will take joint effort from both you and your farrier. Thrush, and other hoof problems, will likely continue to develop and never resolve if you are not involved in the daily responsibility of caring for your horse’s hooves. Fulfilling this responsibility will help prevent future cases of Thrush. This responsibility can be broken down into three components.

  1. Maintenance
  2. Nutrition
  3. Environment

Hoof Maintenance

There is more to hoof maintenance than scheduling your farrier every six weeks. Proper hoof maintenance is a daily objective that the horse owner must manage.

  • Pick and Clean Hooves
    • A hoof packed with debris creates the perfect anaerobic, or low oxygen, environment for Thrush to develop and spread. As the horse owner, it is your responsibility to ensure your horse’s hooves are being picked clean daily.
    • If you remove the debris daily, Thrush will not likely have a suitable environment to develop.
  • Maintain a Regular Farrier Schedule
    • As mentioned in a previous blog, it is important to maintain a regular farrier schedule. Your farrier can help catch early signs of hoof related issues and assist in treating Thrush. Hooves that are grown out or not trimmed properly can trap unwanted debris, making it more difficult to keep the hoof clean and create an optimal environment for the growth of the anaerobic microbes associated with Thrush.
  • Remove Harmful Hoof Topicals
    • Many “Thrush Killing” hoof topicals on the market are caustic and damage or seal off healthy hoof tissue. This may kill the exposed Thrush microbes on the surface; however, the resulting denatured proteins not only seal the underlying tissue from oxygen, but also create a nutrient medium for any remaining microbes and future microbes to thrive. This often leads to patterns of recurring Thrush. It is important to stay away from caustic hoof remedies for Thrush

Equine Nutrition

You may be asking, “What role does Nutrition play when fighting Thrush in Horses?” Nutrition plays a vital role in the development of a healthy hoof. A healthy hoof is more resilient to the bacteria that causes Thrush. As the horse owner, it is your responsibility to ensure your horse receives a balanced diet that supports hoof health. You can learn more about proper equine nutrition here.

  • Hoof Supplementation
    • Quality hoof supplements can assist in developing new and healthier hoof growth. The nutrients provided will also strengthen the hoof, making it more resilient to chips and cracks, acting as entry points for the microbial invasions that lead to crumbly hoof horn, White Line Disease and Thrush. This new growth will also quicken the recovery time of the hoof.

Environment

Even with proper maintenance and nutrition, the environment can wreak havoc on your horse’s hooves. Most cases of Thrush are predisposed by environmental conditions. Leaving your horse in wet and mucky areas or in unclean paddocks can quickly destroy the hoof. You will promote chronic Thrush if your horse is regularly being exposed to these environments. It is important to consistently manage the environment surrounding your horse.

  • Environmental Management
    • Keep stalls clean of excrement and as dry as possible.
    • Limit exposure, if possible, to wet and muddy paddocks and pastures.
    • Regularly apply a non-caustic hoof conditioner to control moisture balance, bind ammonia from excrement and kill bacteria.

When left unchecked, Thrush can become a serious issue and even lead to lameness. It is important to act at the first signs of Thrush and not wait until it becomes more serious. Through proper hoof management, horse owners can not only treat current cases of Thrush but can also prevent future cases from developing. Always consult your farrier and veterinarian if your horse develops any hoof related issue.
