Things must seem to have come to a pretty pass when a book is gravely written upon dyspepsia in dogs. Nevertheless, I am in earnest when I treat upon that subject; and could the animals concerned bear witness, they would testify it was indeed no joke. The Lord Mayor of London does not retire from office with a stomach more deranged than the majority of the canine race, shielded by his worshipful authority, could exhibit. The cause in both instances is the same. Dogs as they increase in years seem to degenerate sadly; till at length they mumble dainties and relish flavors with the gusto of an alderman. Pups even are not worthy of unlimited confidence. The little animals will show much ingenuity in procuring substances that make the belly ache; and, with infantine perversity, will, of their own accord, gobble things which, if administered, would excite shrieks of resistance. A litter of high-bred pups is a source of no less constant annoyance, nor does it require less incessant watching, than a nursery of children. There is so much similarity between man and dog that, from fear of too strongly wounding the self-love of my reader, I must drop the subject.

Indigestion in dogs assumes various forms, and is the source of numerous diseases. Most skin affections may be attributed to it. The inflammation of the gums, the foulness of the teeth, and the offensiveness of the breath, are produced by it. Excessive fatness, with its attendant asthma and hollow cough, are to be directly traced to a disordered digestion. In the long run, half of the petted animals die from diseases originating in this cause; and in nearly every instance the fault lies far more with the weakness of the master than with the corruptness of the beast. He who is invested with authority has more sins, than those he piously acknowledges his own, to answer for.

The symptoms are not obscure. A dislike for wholesome food, and a craving for hotly spiced or highly sweetened diet, is an indication. Thirst and sickness are more marked. A love for eating string, wood, thread, and paper, denotes the fact; and is wrongly put down to the prompting of a mere mischievous instinct: any want of natural appetite, or any evidence of morbid desire in the case of food, declares the stomach to be disordered. The dog that, when offered a piece of bread, smells it with a sleepy eye, and without taking it licks the fingers that present it, has an impaired digestion. Such an animal will perhaps only take the morsel when it is about to be withdrawn; and, having got it, does not swallow it, but places it on the ground, and stands over it with an expression of peevish disgust. A healthy dog is always decided. No animal can be more so. It will often take that which it cannot eat, but, having done so, it either throws the needless possession away or lies down, and with a determined air watches "the property." There is no vexation in its looks, no captiousness in its manner. It acts with decision, and there is purpose in what it does. The reverse is the case with dogs suffering from indigestion. They are peevish and irresolute. They take only because another shall not have. They will perhaps eat greedily what they do not want if the cat looks longfully at that which had lain before them for many minutes, and which no coaxing could induce them to swallow. They are, in their foibles, very like the higher animal.

The treatment is simple. The dog must be put upon, and strictly kept upon, an allowance. Some persons, when these animals are sent to them, because the creatures are fat and sickly, shut the dogs up for two or four days, and allow them during the period to taste nothing but water. The trick often succeeds, but it is dangerous in severe cases, and needless in mild ones. This is a heartless practice, which ignorance only would resort to; but such conduct is very general, and the people who follow it boast laughingly of its effect. They do not care for its consequences. A weakly stomach cannot be benefited by a prolonged abstinence. I have kept a dog four-and-twenty hours without food, but never longer, and then only when the animal has been brought to me with a tale about its not eating. The report, then, is assurance that food has been offered, and the inference is that the stomach is loaded. A little rest enables it to get rid of its contents, and in some measure to recover its tone. The dog, as a general rule, does well on one meal a day; afterward, the food is regularly weighed, and nothing more than the quantity is permitted. This quantity may be divided into three or four meals, and given at stated periods, so that the last is eaten at night. When thus treated, animals, which I am assured would touch nothing, have soon become possessors of vigorous appetites. At the same time, exercise and the cold bath every morning is ordered; and either tonic or gentle sedatives, with alkalies and vegetable bitters, are administered. The following are the ordinary stomach-pills, and do very well for the generality of cases:—

Make into sixteen, thirty, or eight pills, and give two daily.

The reader, however, will not depend upon any one compound, for stomach disease is remarkably capricious. Sometimes one thing and sometimes another does a great deal of good; but the same thing is seldom equally good in any two cases. Stimulants, as nitrate of silver, trisnitrate of bismuth, or nux vomica, are occasionally of great service; and so also are purgatives and emetics, but these last, when they do no benefit, always do much injury. They should, therefore, be tried last, and then with caution, the order being thus:—Tonics, sedatives, and alkalies, either singly or in combination, and frequently changed. Stimulants and excitants in small doses, gradually increased. Emetics and purgatives, mingled with any of the foregoing. The food and exercise, after all, will do more for the restoration than the medicine, which must be so long continued that the mind doubts whether it is of any decided advantage. The affection is always chronic, and time is therefore imperative for its cure.

Dogs are afflicted with a disease of the stomach, which is very like to "water-brash," "pyrosis," or "cardialgia," in the human being. The animals thus tormented are generally fully grown and weakly: a peculiarity in the walk shows the strength is feeble. The chief symptom is, however, not to be mistaken. The creature is dull just before the attack: it gets by itself, and remains quiet. All at once it rises; and without an effort, no premonitory sounds being heard, a quantity of fluid is ejected from the mouth, and by the shaking of the head scattered about. This appears to afford relief, but the same thing may occur frequently during the day. This disease of itself is not dangerous; but it is troublesome, and will make any other disorder the more likely to terminate fatally; it should, therefore, be always attended to. The food must not be neglected, and either a solution of the iodide of potassium with liquor potassÆ, or pills of trisnitrate of bismuth, must be given. The preparations of iron are sometimes of use; and a leech or two, after a small blister to the side, has also seemed to be beneficial. When some ground has been gained, the treatment recommended for indigestion generally must be adopted, the choice of remedies being guided by the symptoms. The practitioner, however, must not forget that the mode of feeding has probably been the cause; and, therefore, it must ever after be an object of especial care. The cold bath and exercise, proportioned to the strength, are equally to be esteemed.

Very old dogs often die from indigestion, and in such cases the stomach will become inflated to an extent that would hardly be credited. These animals I have not observed to be subject to flatulent colic; when, therefore, the abdomen becomes suddenly tympanitic the gas is usually contained in the stomach. Fits and diarrhoea may accompany or precede the attack, which in the first instance yields to treatment; but in a month more or less returns, and is far more stubborn. Ether and laudanum, by mouth and enema, are at first to be employed; and, generally, they are successful. The liquor potassÆ, chloride of lime in solution, and aromatics with chalk, may also be tried, the food being strengthening but entirely fluid. The warm bath is here highly injurious; and bleeding or purging out of the question. When the distension of the stomach is so great as to threaten suffocation, the tube of the stomach-pump may be introduced; but, unless danger be present, the practitioner ought to depend upon the efforts of nature, to support which all his measures should be directed. After recovery, meat scraped as for potting, without any admixture of vegetables, must constitute the diet; and while a sufficiency is given, a very little only must be allowed at a time. With these precautions the life may be prolonged, but the restoration of health is not to be expected.
