Daily cleaning, of the hooves and the environment, is the best way to prevent of thrush. In the driest part of the summer Mr. Finn advises horse owners to replenish moisture to coronary bands and bulbs of the hooves with hoof lotion. However, he cautions that lotion applied to the sole can create a very soft, tender, and easily bruised foot. Also lotion is unnecessary on the hoof wall because it cannot penetrate there. If you are showing, find someone who shoes for that style.
Some farriers can shoe many different horses and do therapeutic shoeing.
Others specialize and shoe only arabs, saddlebreds, walking horses, or quarter horses. Simple, but extremely important. For more information on equine health, contact your local equine veterinarian.
