Hoof-Bound, an unnatural contraction of a horses hoof, on the top and at the heel, so that the skin appears to grow over the hoof . It is easily discovered by the fre -quent halting of the horse, and the ho low sound of the disceased hoof: it arises from various causes, such as keeping him too dry in the stable ; an injudicious method of shoeing ; paring the soles as often as the annual is shod, etc.
As this malady always approaches gradually, it may be relieved at the commencement of every stage, or species of it, by proper manage-ment ; but, if it become inveterate, no art whatever can effectually remove it.
The first species proceeds, in general, from the injudicious use of concave shoes, or from paring and hollowing out the sole and binders as often as the shoes are renewed. Hence, t;.e heels become so thin, that the crust at the extremity may be forced into contact by the slightest pressure ; the contraction of the hoof at length becomes general, and incurable. The only remedy in this case is, to keep the: hoots cool and moist, never to suffer them to be greased, or the soles to be pared, and to use only flat, narrow, and open-heeled shoes. Thus the stricture on the heels and frog will be in some measure removed, the animal affected considerably relieved, and the disorder at length so far palliated, as to enable him to walk with more firmness.
In the second stage of this evil, the crust at the coronet becomes contracted ; the annular ligament compressed ; and the hoof acquires the shape of a bell ; the conse-quence of which is lameness. With a view to cure this, Mr. Gibson proposes to trace several lines on the tore-part of the hoof with a drawing-knife, almost to the quick, from the coronet down to its basis, a d then to turn the animal out to grass : others advise, after this operation is performed, to screw the heels wide, by means of a screwed shoe. A third method is, to draw the sole, and divide the fleshy substance of the frog with a knife, keeping it likewise separated by the screwed shoe. In recent con-tractions, either of these method;) may be applied, and if dexterously managed) they will afford consi-cerable relief.
The last species is a contraction of one, or frequently of both heels, in.flat feet, from the use of concave shoes, etc. The best remedy in this case is, to lay aside such improper shoes ; to pare or rasp to the quick the whole contracted quarter of the crust near the heel, but without drawing blood : a bar-red shoe is then to be put on, so as make, the bar of the shoe press up-on the frog; the hoof should be kept moist, and the diseased animal turned out to grass. Thus the Stricture of the hoof will gradually disappear, the contracted part- expand, and a new hoof grow from the coronet downwards, that will acquire a round, proper shape, and in a short time the horse will be re-Stored to his former activity.
