The ulcers of foul in the foot usually occur about the coronet and extend under the hoof, causing much inflammatory action, very great pain, and more or less separation of the hoof; but they often originate in uneven pressure upon the sole, and rise upward from a crack between the claws, and are principally or wholly confined to one side or claw of the foot. A fetid purulent discharge proceeds from the ulcers, and a sinus may sometimes be discovered by means of a probe to descend from the coronet beneath the hoof. The affected animal is excessively lame, and may possibly suffer such a degree of pain as to lose all appetite and become sickly and emaciated. If the disease is of a mild form, or be merely in the initiatory stage, it may be readily cured by cleaning, fomentation, and rest; if it be of a medium character, between mild and violent, it may be cured by cleaning, by carefully paring away loose and detached horn, by destroying any fungus growth, and by applying, with a feather, a little butyr of antimony; and if it be of a very bad form, or has been long neglected, it will require to be probed, lanced, or otherwise dealt with according to the rules of good surgery, and afterwards poulticed twice a day with linseed meal, and frequently, but lightly, touched with butyr of antimony. Founder. This disease consists in inflammation of the laminae and of the vascular parts of the sensible foot. It sometimes attacks only one foot, sometimes two, and sometimes all four; but, in a great majority of cases, it attacks either one or both of the front feet. A chronic form sometimes occurs, and exhibits symptoms somewhat similar to those of contraction of the hoof; but acute inflammation of the laminae is what is generally called founder. This disease is occasioned by overstraining of the laminae from long standing, by prolonged or excessive driving over hard roads, by congestion from long confinement, by sudden reaction from standing in snow after being heated, or from covering with warm bedding after prolonged exposure to cold, by sudden change of diet from a comparatively cool to a comparatively heating kind of food, and by translation of inflammatory action from some other part of the body, particularly after influenza. In the early stages of founder, a horse evinces great pain, shows excessive restlessness of foot, and tries to lighten the pressure of his body on the diseased feet. In the more advanced stages he is feverish, breathes hard, has violent throbbing in the arteries of the fetlock, lies down, stretches out his legs, and sometimes gazes wistfully upon the seat of the disease; and in the ulterior stages, if no efficacious remedies have been applied, the diseased feet either naturally recover their healthy condition, or they suppurate, slough, cast part or all of the hoof, and gradually acquire a small, weak, new hoof, or they undergo such mortification and change of tissues as to render the animal permanently useless.
