Many horse breeders know that unpleasant feeling when the veterinarian voiced the diagnosis. This is especially difficult if the horse suffers from allergies or upper respiratory tract diseases such as dyspnea or drusen. In case of such diseases, it is important, first of all, to keep the horse in a clean stall protected from dust, where there is no fungal bacteria and mold. Often, improper feeding of the horse leads to blockage of the esophagus and colic, which can sometimes be fatal. Moisture in a horse stall causes hoof disease, such as falling out of the hoof wall (horn), many types of ulcers on the hoofs, or laminitis. Therefore, horse care is a very difficult and demanding task, which requires a lot of attention from horse breeders and horse owners.
