Upon first inspection you will notice a foul odor with a gray, cheesy material between the frog and the bars of the foot. Most severe cases are generally located in the cleft of the frog which is the deep area between the bulbs of the heels. The frog has an overall, ragged appearance. The horse is generally sensitive to the hoof pick in the deeper locations. Probing in these areas may cause bleeding.
Most thrush is caused by neglect.
Keep the feet as clean and as dry as possible. Provide a clean stall. Regular farrier attention will help maintain a healthy foot. Keep your horse well fed and exercised. A healthy horse is less likely to become infected.
