The water should always be mixed without the building; it is never well to excite an animal's fears by allowing it to witness unnecessary preparation. The author is fully aware that most people assert the horse has a very limited comprehension: so it may have; but it has an active terror, which is apt to misconstrue the simplest of motives. Whoever has seen the busy eye of the quadruped watching all that takes place around it, and noting every triviality whenever any unusual movement gives intimation to the animal that something is about to be attempted, will readily allow the need there is for excessive caution. The horse may comprehend nothing, but it is not, therefore, the less to be propitiated. Its terror has to be soothed and its confidence has to be gained; the last is soonest won by avoiding anything which possibly might excite the first.
Always have the heat of the water ascertained by a thermometer. Sensation is only a relative test with regard to the presence or absence of warmth; were it not so, the coarse hand of a groom, nevertheless, might easily endure that degree of temperature which should pain the foot and leg of a horse. Let the fluid in the first instance stand at 70°; after the animal has entered the bath, gradually and without noise increase the temperature up to 90°.
At that standard the water ought to be maintained; the hoof should remain soaking from four to six hours at each operation; the groom, doubtless, will complain of having frequently to fetch warm water, and when not so employed, of being obliged to watch a thermometer; but the present book is not written to please the likings of any individual. To contribute to the welfare of the horse is the object of the writer; that he has not unnecessarily imposed an irksome duty upon any human being, the purpose for which the bath is introduced into the stable should be sufficient evidence.
The horse's hoof is of considerable thickness; it is far from unusual with stablemen to saturate the healthy hoof with various greasy preparations; therefore it will require some time before the heat and water can soften that which is, as it were, prepared to resist their action. The hoof should be rendered perceptibly soft when the object is to relieve a painful lameness; the warmth and moisture should not only saturate the covering to the foot, but should also soothe the internal structures. The pressure of the horn may thus be mitigated, and the deep-seated inflammation likewise be ameliorated.
When the bath is removed, the foot should not be left exposed to the air, as the horn then quickly dries; it soon becomes harsh and brittle. In this condition, it is likely to do more injury to the sensitive parts than good was anticipated as the consequence of its immersion. The hoof, when taken from the water, should be incased in warm and air-proof bandages—the intention being to retain the heat, while evaporation is prevented. The bandages likewise answer another purpose; they protect the foot, which, being without a shoe, and covered by horn that has been deprived of its resistant property, is therefore much exposed to accidents.
To obtain the full benefit of the bath, the foot should enter it night and morning; the animal should be subjected to its operation for at least four hours each time, and the ingenuity ought to be exerted to prevent the hoof from becoming dry in the interim. Perhaps nothing is better for this purpose than the leather case, which is lined with sponge, and which can be procured of most tradesmen who deal in veterinary instruments; it is made to fit the foot, also to envelop the pastern. The bottom portion is formed of the stoutest leather, and will afford all desirable protection; while the sponge will retain the moisture, which this material permits to be renewed, should circumstances, such as the heat of the hoof or the warmth of the weather, cause the fluid to evaporate. However, such additions must always be made with warm, cold water being unsuited for the purpose.
These particulars have been thus fully detailed because lameness constitutes no inconsiderable portion of equine misery, and because such ailments are more frequently encountered than special forms of disease. To judge quickly and surely of such affections proves in no small degree veterinary proficiency; in every shade of lameness, the gentleman, unless more than usually practiced in such ailments, had better be guided by an educated opinion. Where it is possible to mistake another's misery, it displays no boldness to risk chances upon our own judgment.
Lameness is simply the difference of bearing cast, during progression, upon the several legs. Pain in the joints, bones, or tendons is most severe. It is even more terrible when inflammation of such structures is confined within the horny hoof; of this torture man can know nothing—he may rest the angry limb, may recline the body, or may seek consolation in friendly converse and in mental diversion. From all the higher pleasures the horse is excluded. It cannot rest the leg; and the instinctive dread which the sick animal displays of being unable to rise again prevents the quadruped seeking that relief a change of posture might afford.
The horse always stands when seriously diseased; often the erect position is continued to the last, for the sufferer ceases to maintain it only with the relinquishment of life. During severe lameness in one foot, the animal seldom lies down; it stands and stands, often for months. How the limbs must ache! Yet the relief which the slightest motion might induce is avoided with the tenacity which pain begets when operating upon excessive timidity. Often one spot is occupied for months! During this tedious period one foot is held from the earth. The mind shrinks from conjecturing the torture which could prompt such an act; the reason retreats from contemplating the agony by which the deed can alone be occasioned; we shudder as the imagination remotely pictures the pains by which it must be accompanied! Yet who has been much among stables, and has not witnessed many such sights?
