Inflammation of the kidneys is generally caused by riding or driving a horse immoderately, by straining the loins, in making him draw heavy loads or carry heavy burthens; or they may become inflamed in consequence of peritonæal inflammation of the bowels. In either case breed freely, or to faintness; cover the loins with a fresh sheep skin, the flesh side under, having first rubbed on them some warm embrocation, such as hartshorn and oil, with a little oil of turpentine, or the following embrocation. Open the bowels with a dose of castor oil and clysters of warm water, with a small quantity of salt and oil, or hog’s lard. I should first have noticed, however, the symptoms of the disorder, which are, a constant desire to make water, without being able to void any, or scarcely any: and the little that is discharged is dark coloured or bloody. There is great stiffness of the hind parts, generally more observable in one leg than the other. The horse often stands straddling or wide, as if in want to make water, and every now and then straining, or making painful and ineffectual efforts to stale. This appearance often leads the groom to think that it is a stoppage of water, and that a diuretic is necessary; but the fact is, that the dark-coloured or bloody urine is so stimulating or acrimonious that the bladder contracts violently in order to force out the smallest quantity that gets into it.
The disorder I have now been describing may happen in various degrees, but still the treatment is the same. It sometimes happens, however, that the urine becomes foul and stimulating from high feeding, or foul and unwholesome feeding. In this case the bladder will contract upon a small quantity of urine, and the urine may be rather high coloured, like beer, or turbid, like whey, and the horse may appear to strain a little in voiding it; but this is very different from those distressing symptoms which attend inflammation of the kidneys, nor is it accompanied with loss of appetite, or any degree of fever, which is always present in inflammation of the kidneys. When the urine becomes thus stimulating, some cold mashes, with a little nitre, may be given, or what is still better, perhaps, some grass, vetches, or lucern. If the horse is at all costive, a clyster should be thrown up. An infusion of linseed is a good drink for a horse when the urine is in this state.
The improper manner in which horses are generally fed, the early age at which they are worked, and the immoderate degree in which they are often worked, are circumstances which either separately or conjointly tend to weaken the stomach, and disturb the digestive functions; in consequence of this the blood becomes foul, or loaded with excrementitious matter, the greatest part of which, in the horse, is carried off by the kidneys. This renders the urine more acrimonious than it would otherwise be, and causes the bladder to contract upon a smaller quantity. We may often observe, also, how the urinary passages are stimulated by such urine, making mares appear as if they were horsing, and causing an erection in geldings. As the horse is often staling in this case, and voiding but a small quantity, and appearing as if he was endeavouring to void more, it is often mistaken for a stoppage in the water, as it is termed, and diuretics are generally given, which, if not too strong, may be of service. But the best plan is to keep the horse on bran mashes chiefly for a few days, and give twice a day, for two or three days, the following powder:—
| Nitre | 3 or 4 dr. |
| Carbonate of soda | 1 dr. or chalk 2 dr. |
| Mix for one dose. | |
Or, No. 2, Nitre, powdered resin, chalk, and levigated antimony, of each two drachms.—Mix for one dose.
If these powders appear to disagree with the stomach they should be discontinued: in such cases the cordial diuretic is more likely to do good, such as has been prescribed for asthmatic affection or broken wind.
