Dogs are abused for their depraved tastes, and reproached for the filth they eat; but if one of them, being of a particular disposition in the article of food, takes to killing his own mutton, he is knocked on the head as too luxurious. It is a very vulgar mistake to imagine the canine race have no preferences. They have their likes and dislikes quite as strong and as capricious as other animals. Man himself does not more frequently impair his digestion by over indulgence than does the dog. In both cases the punishment is the same, but the brute having the more delicate digestion suffers most severely. The dog's stomach is so subject to be deranged that few of these creatures can afford to gormandize; to which failing, however, they are much inclined. The consequence is soon shown. A healthy dog can make a hearty meal and sleep soundly after it. The petted favorite is often pained by a moderate quantity of food, and frequent are the housemaid's regrets that his digestion is not more retentive. He spoils other things besides victuals; and the more daintily he lives the more generally is he troublesome. It is the variety that diseases him. He grows to be omnivorous. He learns to relish that which nature did not fit him to consume, and as a consequence he pays for his bad habits. The dog in extreme cases can digest even bones; a banquet of tainted flesh will not disorder him; but he cannot subsist in health on his lady's diet. His stomach was formed to receive and assimilate certain substances, and to deny these is not to be generous or kind.

Gastritis is very common with ladies' favorites. Its symptoms are well marked. Frequent sickness is the first indication. This is taken little notice of. The mess is cleared up, and the matter is forgotten. Thirst is constant, and the lapping is long; but no further notice is taken of this circumstance, than to remark the animal has grown very fond of water. At last the thirst has increased, and no sooner is the draught swallowed than it is ejected. The appetite which may have been ravenous a little time before, now grows bad, and whatever is eaten is immediately returned. The animal is evidently ill. The nose is dry, and the breathing quick. It avoids warmth, and lies and pants, away from the hearthrug. It dislikes motion and stretches itself out, either upon its chest or on its belly. Sometimes it moans, and more rarely cries. The stomach is now inflamed; and if the symptoms could have been earlier understood, frequently has the animal been seen, prior to this stage of attack, licking the polished steel fire-irons. It has been horrifying its mistress's propriety, by its instinctive desire to touch something cold with its burning tongue; and the poor little beast perhaps has been chastised for seeking a momentary relief to its affliction.

Dogs that are properly treated rarely have gastritis. When they do, it is generally induced by some unwholesome food. I have known it to be caused by graves more often than by anything else they are accustomed to eat. I never recommend this stuff to be given to dogs. Meal and skim milk is far better, and that can always be procured where flesh is scarce. The entrails of sheep, &c., if washed and boiled with a large quantity of any kind of meal, are nutritious and wholesome; nay, even when a little tainted, they will not be refused. If, however, they were hung up in a strong draught, they would soon dry; and in that state might be preserved for use any length of time; all they afterwards require would be boiling. The paunch can be prepared in the same manner; and it would be worth some little trouble to avoid a mixture which contains nothing strengthening, and too often a great deal that is injurious.

The treatment of gastritis is simple. It is generally accompanied by more or less diarrhoea; but the violence of the leading symptom renders that of comparatively little consequence. The degree of sickness will always indicate whether the stomach is the principal seat of disease.

As nothing is retained, it would be a needless trouble to give many solids or fluids, by the mouth. From half a grain to a grain and a half of calomel, thoroughly mixed with the same quantities of powdered opium, may be sprinkled upon the tongue; and from one drachm to four drachms of sulphuric ether may be given in as much water as will dissolve it twenty minutes afterwards. The medicine will most probably be ejected; but, as it is very volatile, it may be retained sufficient time to have some influence in quieting the spasmodic irritability of the stomach. Ethereal injections should be administered every hour, and no food of any kind allowed. Besides this, from a quarter of a grain to a grain of opium may be sprinkled on the tongue every hour; and the ether draught continued until the sickness ceases, or the animal displays signs of being narcotised. An ammoniacal blister, if the symptoms are urgent, may be applied to the left side; but in mild cases, a strong embrocation will answer every purpose. Except the constitution be vigorous, and the pulse very strong, it will not be advisable to bleed, but from two to twelve leeches may be applied to the lower part of the chest. Cold water may be allowed in any quantity, but nothing warm should be given. The colder the water, the better, and the more grateful it will be to the animal. Where it can be obtained, a large lump of ice may be placed in the water, for the dog often will lick this, and sometimes even gnaw it. Small lumps of ice may be forced down as pills, and a cold bath may be given, the animal being well wrapped up afterwards, that it may become warm, and the blood, by the natural reaction, be determined to the skin.

When the sickness is conquered, the following should be administered:—

The above may be repeated every four hours until the stomach is quiet; but it is not always tranquillized; sickness may return, and the pills may possibly seem to aggravate it. If such should appear to be the case, try the next:—

The ether and opium must also he persevered with, regulating the last of course by the action which it induces.

Food should consist of cold broth, slightly thickened with ground rice, arrowroot, starch, or flour, and for some days it must be composed of nothing more; but by degrees the thickness may be increased, and a little bread and milk introduced. After a time a small portion of minced underdone meat, without skin or fat, may be allowed; but the quantity must be small, and the quality unexceptionable.

The second day generally sees an abatement of the more urgent symptoms, and then the draught may be composed of five minims of laudanum to every drachm of ether, and ten drachms of water. This to be given both by mouth and injection six times daily. The former pills were intended only to allay the primary violence of the disease, and when that object is attained, the following remedy may be employed:—

The above is for one pill, which should be repeated four times daily, and continued for some days; when, if the dog seems quite recovered, a course of the quinine tonic pills, as recommended for distemper, will be of use; but should any suspicion be created of the disorder not being entirely removed, the animal may be treated as advised for indigestion.

Sporting dogs are frequently sent to me suffering under what the proprietors are pleased to term "Foul." The history of these cases is soon known. They have been withdrawn from the field at the close of the season, and have ever since been shut up in close confinement, while the working diet has been persevered with. The poor beast is supposed capable of vegetating until the return of the period for shooting requires his services. He remains chained up till he acquires every outward disease to which his kind are liable; and then, when he stinks the place out, his owner is surprised at his condition, pronouncing his misused animal to be "very foul." "Foul" is not one disease, but an accumulation of disorders brought on by the absence of exercise with a stimulating diet. The sporting dog, when really at work, may have all the flesh it can consume; but at the termination of that period its food should consist wholly of vegetable substances, while a little exercise daily is necessary, not to health, but absolutely for life. The dog with "foul" requires each seat of disease to be treated separately; beginning of course with the dressing for mange or for lice, one or the other of which the animal is certain to display.
