The Dog
BOWEL DISEASES
Continuous with the stomach are the intestines, which are equally subject to disease, and more exposed to it in an acute form than even the former viscus. The dog will fill its belly with almost anything, but there is little that positively agrees with it. Boiled rice or lean meat, &c., and coarse biscuit, are the best general food; but without exercise, even these will not support health. The dog requires constant care if it is deprived of liberty: and those who keep these animals as pets, must submit to trouble, for though art may do much, it cannot conquer Nature.
The intestines of the dog are peculiar. In the first place, it has no colon, and all the guts are nearly of one size from the commencement to the termination; the duodenum and the most posterior portion of the rectum being the largest, though not so much so as materially to destroy the appearance of uniformity. The cæcum is no more than a small appendage – a little sac attached to the main tube; it has but one opening, and that is very diminutive. I think all the food, as in other animals, passes into and out of this intestine; which, because of its peculiar formation, is therefore particularly liable to be disordered. In the dog which has died of intestinal disease, the cæcum is almost invariably found enlarged and inflamed. In it, I imagine, the majority of bowel affections have their origin. The gut is first loaded, and the consequence of this is, it loses its natural function. The contents become irritants from being retained, and the whole process of digestion is deranged; other parts are involved, and inflammation is induced.
Writers do not notice the tendency of the cæcum to be diseased, or remark upon its disposition to exhibit signs of alteration; but the fact being so obvious, I wonder it should have escaped observation.
Costiveness is, in some measure, natural to the dog, and in that animal is hardly to be viewed as a disease. In health, the fæces are not expelled without considerable straining, and the matter voided ought to be of a solid character. It nevertheless should not be absolutely hard, or positively dry, for in that case the want of moisture shows the natural secretion of the rectum is deficient; the hardness proving prolonged detention, denoting the intestines have lost their activity.
Both Blaine and Youatt were educated in the old school of medicine, which taught them to regard purgatives as the surgeon's best friends, and the sheet-anchors of his practice. They prescribe them in almost every case, and almost on every occasion; but I rarely give these agents. In the dog I am convinced they are not safe, and their constant use is by no means imperative. Should an animal be supposed not to have been relieved for a week, this fact is no proof that a purgative is required. The animal may have eluded observation, and it cannot inform us if such has been the case. The intestines may be slow, or the digestion may be more than usually active. It is foolish to lay down rules for Nature, and punish her creatures if these laws are not obeyed. There are, however, means of ascertaining when a purgative is needed; and these, if employed, will very rarely deceive.
The muscles covering the abdomen of the dog are very thin, and through them the contents of the cavity may be plainly felt. By squeezing these together, the fingers will detect whether the rectum, which lies near to the spine, and of course backward or towards the tail, contains any substance. Should the presence of any solid body be ascertained, its character ought to be noted. If round and comparatively soft, a little exercise will cause it to be expelled; but if hard-pointed in places, and uneven, assistance should be afforded. An enema, of the solution of soap – or of Epsom salts, from half an ounce to a quarter of a pound, in a quarter of a pint to a quart of water – may be administered. A more active injection will be, from half a drachm to four drachms of turpentine, beaten up with the yolks of so many eggs as there are drachms of the oil, and mixed with the quantity of water just named.
Either of these will relieve the bowel; but the condition of one part justifies an inference as to the state of another, and the enema probably will not unload the cæcum, which there is reason to suppose is also clogged. A gentle dose of castor-oil, or of the pills directed on page 116, will accomplish this intention; and, afterwards, measures must be adopted to regulate the digestion, either by tonics or such medicines as the symptoms suggest, but not by the constant repetition of laxatives.
Costiveness will sometimes produce such violent pain that alarm is created, and dogs have been destroyed under the idea that they were rabid. To guard against so fatal a mistake, I shall only here say, that rabies does not come on suddenly, or, save in the latest stage, appear to influence the consciousness, which it never entirely overpowers. The agony caused by costiveness is greater than in any other affection to which the dog is liable. Apparently well, and perhaps at play, a cry breaks forth, which is the next instant a shriek, expressive of the acutest torture. The animal takes to running, and is not aware of surrounding objects; it can recognise nothing, but will bite its master if he attempts to catch it, and hit itself against anything that may be in its way; it scampers from room to room, or hurries from place to place; it is unable to be still or silent; and perhaps getting into a corner, it makes continuous efforts as though it wished to scramble up the wall, remaining there jumping with all its strength, and at the same time yelling at the top of its voice. This excitement may last for an hour or more, and then cease only to be renewed: till at length the powers fail, and in half a day the animal may be dead. Just prior to death, a mass of compact fæces is usually passed; and blood, with dysentery, is generally witnessed for the short period the animal survives. After death, general inflammation of the intestines is discovered, and the dog is reported to have perished from an attack of enteritis which no medicine could subdue.
In such cases, the first examination should be directed to the rectum; the finger, moistened or oiled, ought to be inserted, and the intestine explored as thoroughly as possible. This operation is, however, not of further use than to confirm the opinion of the practitioner; and I, knowing the cause, therefore dispense with it. A copious enema should be immediately exhibited. One containing turpentine is the most effective; but, on account of its activity, it is only safe in the beginning of the attack. A warm bath is of service, but it takes up time which may be better employed, and does not do sufficient good to recompense for the delay. A full dose of sulphuric ether and laudanum should be given to allay the pain, and it may with this intention be repeated every ten or twenty minutes. If, from the enema, nothing follows, the finger should then certainly be introduced, and perhaps a compact mass may be felt firmly grasped by the intestine. Slowly, and with great caution, this must be broken up, and brought away bit by bit. The handle of a spoon has been recommended for this purpose, but I entreat my readers not to use it. Where pain is present, and life or death hang on the issue, there is no right to be any delicacy. An instrument of any kind introduced into such a part, and employed while the body is writhing about in agony, cannot be free from danger, and scarcely can be so used as to be effective. The finger is the quickest, the most safe, and the most effectual instrument; for we have it under our command, can guide it at our will, and with it take cognisance of all the circumstances presented. Even that must be employed gently, and this will be best done by the avoidance of haste. The surgeon is bound to be skilful, but he ought never to be in a hurry. Let all the time that can be occupied on such a matter be freely taken, and during the process, let the cries of the animal be attended to; any change of note will contain a warning which must not be disregarded. Without attending to that, the intestine might be ruptured, and death would then be certain.
When the obstruction has been overcome, let a few ethereal enemas be administered to allay any local irritability; and a dose of the purgative pills – followed, six hours afterwards, should they not have operated, by one of castor-oil mixture, blended with half a scruple of chloroform – being given to unload the cæcum. The medicine having acted freely, the food must be amended, the treatment altered, and such other measures taken as the digestion may require for its restoration.
Colic. – This is an affection to which dogs are very subject. The human infant is not more liable to be griped than are the young of the canine species. The idea of a cur with a belly-ache may, to some persons, seem to be suggestive of fun; but to the creature that suffers, it is indeed a serious business. A duchess with the spasms does not endure so much, and is not in half the danger, that a dog is exposed to during a fit of gripes. The animal must be relieved, or inflammation will speedily ensue, and death will follow. In some cases, the appearance of colic is almost a certain indication that the poor beast will die. When it comes on a week or two prior to pupping, we may cure it; but during, or soon after parturition, the bitch generally perishes. When it starts up in the later or more virulent stage of distemper, especially at the time when the champing of the jaw denotes the approach of fits, the chance of a favorable termination to the disease is materially diminished. When in a violent form it attacks a litter of puppies, either simultaneously or consecutively, it is always attended with danger. At no season, and under no circumstances, is it trivial, and never ought it to be neglected. The cries and distress of the suffering animal will, when it is fully established, enforce attention; but too often it has then proceeded so far that much medicine will not check what in the first instance a single dose might have entirely banished.
The symptoms of colic have been much confused by Blaine, who, when describing them, evidently alludes to many forms of disease with which abdominal spasm has no connexion. Youatt is far more clear; but he is too concise, and omits so much that the reader does not properly appreciate the importance of that affection which is thus slightly mentioned. Neither of the two authors seems to have carefully studied the subject; for in their writings is not to be found any account of those early symptoms which most readily yield to treatment.
Prior to evincing any sign of colic, the dog appears well; healthy in its body and easy in its mind. The appetite is good, or may be better than usual. The food has been eaten and relished; then the animal instinctively lies down to sleep and aid digestion. A moan is heard; the sound is half suppressed, and the dog that utters it appears to sleep. Another cry, as feeble, but of greater length, is noticed; and now the animal that made it changes its position. The next time it may rise, look round, and seek another place; which having found, it appears to settle itself and to go to sleep. The rest once more is broken, the voice grows more full and loud; the dog jumps up and runs about for a little while, then selects a spot where it curls its body tightly up, as if resolved to have out its nap. The interruption, however, constantly recurs; and at each return the exclamation is more emphatic – the starting more energetic – the movement more abrupt – and, contrasting these, the determination or desire to repose becomes more strong. Thus endeavoring to sleep, and being constantly disturbed by some sharp and shooting pain, the dog may continue for a day, or two, or three, its cries, during the whole period, offending a neighborhood.
During the continuance of colic, the general appearance of the animal may be but little affected. The eye is not injected, but the pupil may be slightly enlarged. The nose is cool and moist, but towards the end, irritation may render the part hot or dry. The appetite is generally slight – sometimes lost; and fluids are more readily accepted than solids. The cry, however, should be remarked; because, with the pulse, it gives the earliest notice when inflammation is commencing. While colic alone exists, the pulse may, from pain, be accelerated, and rendered more full, as well as strong, though not always to any marked extent. In inflammation, the pulse is greatly quickened, the artery becomes smaller, and its beat more jerking or wiry. During simple spasm the voice is natural, rich, sonorous, and almost musical; but in inflammation it is short, harsh, high, and broken, the exclamations not being continuous, but consisting of a series of disconnected "yaps."
For the treatment, in the first instance, a turpentine enema will frequently cut short the attack. Should it fail to so, injections of ether and laudanum should succeed, and doses of the mixture should also be given every half hour; the first three being exhibited at intervals only of a quarter of an hour each. The cathartic pills should be administered; and in three hours, if the bowels have not been acted upon, a dose of castor-oil should be resorted to; but where the cathartic has been responded to, the castor-oil should be delayed for eight or twelve hours.
When the pain ceases, the ether and laudanum should not be immediately discontinued; but they may be employed at longer intervals, and gradually reduced in quantity, until the bowels are thoroughly opened, when they may be withheld. Under this treatment, the affection is rarely fatal, and never so if taken in time. An injection of ether and laudanum should always be given to any pup that exhibits even the slightest symptom of uneasiness. I have never known it to do harm, but I am convinced it has often prevented danger.
In those cases where purging and other indications denote the coats of the bowels to be already involved, and spasm co-exists with enteritis, ether and laudanum must enter into all the remedies employed. On the dog their action is, in my opinion, always beneficial; and were they not directly so, the influence they possess in deadening pain would be sufficient reason to justify their adoption. The other measures consist of such as will be found mentioned under the head of enteritis; but it is essential to observe any fæces which may be ejected by the animal that has suffered colic; for by these we may sometimes guess the cause of the attack, and more often learn the means through which a return may be prevented.
As to the causes which induce colic, I can of my own knowledge offer no information. It has to me seemed to be regulated by none of those circumstances to which it is generally attributed; at all events, I think I have witnessed it in animals which have not been exposed to any of the causes that teachers and writers assert induce it. Dogs are, however, brought to us only when the cause has ceased; for we are sought for only to treat the effect. The declarations of authors may therefore be correct, although I am unable to corroborate them; and these gentlemen say colic is produced by cold, acrid food, chills, worms, hard water, &c. In cases of this kind, therefore, it may be well to inquire if the dog has been exposed, or badly fed, or is in any way unhealthy; and, so far as possible, to rectify these matters; for, even though they may not have provoked the spasm, nevertheless we shall do good by attending to the health, diet, and comfort of the animal.
Enteritis. – The doom of the dog which is really afflicted with this disease, is generally sealed. It is a painful and a fatal disorder – equally rapid and stubborn. I fear it more than any other affection to which the animal is subject, and more frequently than any other has it set my best endeavors at defiance.
In the dog, however, enteritis is rarely seen in a pure form. The mucous membrane of the intestines is mostly inflamed, but the serous covering, as a general rule, is in no degree involved. The stomach, however, is almost in every instance more or less implicated; its inner surface being inflamed, and its muscular coat so contracted, that the lining membrane is corrugated, and remains in that condition after death.
The incentives are, unwholesome food, which is the most frequent of the causes; exposure, especially after a dog has been in winter fantastically deprived of its long hair over the loins; and over-exertion, to which the dog is often exposed, no attention being paid to its condition. Anything which disorders the digestion, or violently shakes the constitution, will induce it; for in the dog every species of revulsion has a tendency to attack the bowels. Mange improperly treated has produced it; and this may be said of almost any skin disease; so that it has been caused not by true mange or itch alone but by a skin disease having been, under the pretence of working an immediate cure, driven into the system. Neglected impactments, or colic, are among its most frequent immediate causes; for at least three parts of those cases of enteritis submitted to my notice, have been clearly traced to have commenced with something of that kind.
Of the symptoms of enteritis, colic and constipation, with a hard thin pulse, are the most prominent. Sickness is not present, or rather I have not witnessed it, at the commencement of the disorder. The extremities are cold – the eye has a stupid expression, the pupil being much dilated – the breath is hot, and the nose dry. The tail is drawn firmly downward, and pressed upon the anus; the urine is sometimes scanty, always high-colored; the tongue is rough and clammy, the thirst strong, and the appetite lost. The dog seeks darkness and privacy, and does not ramble during the early stage; it will stretch itself out either upon its belly or on its side, and I have not seen it sit upon its haunches. The abdomen is only of the heat of the body, which is generally of an increased temperature. Pressure appears to cause no pain, and the animal rather seems grateful for friction than to resist it. As the disease proceeds, diarrhœa ensues, and with it the signs of exhaustion and death generally are exhibited. Throughout the attack there is a marked disinclination to take any remedy; which is not always displayed by these creatures, and in no other disease is so violently exhibited. Dogs often become attached to those who minister to their complaints; many of them will appear to understand and appreciate the motives of him who attempts their relief. The poor things will frequently submit to operations, and lick the hand which has performed them. Eloquent are the appeals which they sometimes make to the feelings of one in whom they have placed their confidence; often staggering to meet him when he enters; looking upward into his face, and uttering low cries, which are more expressive than words could possibly be rendered. He who has had much to do with dogs must, if he be not insensible, grow to like them, and gradually learn to think these creatures possess both knowledge and reason. They will sometimes, without a struggle, swallow the most pungent and nauseous drinks; but such is not the case during enteritis. The brain in that disease is always sympathetically affected, the state of the eye, its peculiar expression and dilated pupil, denote the fact; and the manner of the dog would, without these indications, lead us to surmise the circumstance.
The treatment must be energetic. The sharp, short cries, characteristic of enteritis, as pointed out in the preceding description of colic, will be sufficient warning of the danger, and ample intimation that there is no time to be lost. A turpentine enema should be injected. The treatment ought always to begin with this, for to unload the rectum is of all importance. Afterwards, from one to four grains of calomel, with from half a grain to two grains of opium, should be shaken upon the tongue; and when ten minutes have elapsed, a draught of ether and laudanum and water, with an injection of the same composition, ought to be exhibited. While the cries last, the ether may be continued, and when the strength appears to fail, it may also be employed. Two hours subsequent to the calomel being given, from half an ounce to three ounces of castor-oil, diluted with half the quantity of olive-oil, should be used as a drench; and thrice during the day the following may be administered either as a pill or draught, in thick gruel, soup, or mucilage, at the option of the practitioner; who will, of course, be guided by the disposition of the patient, which in every particular must be considered: —

Bleeding is of some service, but the dog so quickly sinks, that it must be practised with caution. On this account, as well as for other reasons, leeches are to be preferred. If the patient be a male, they may be applied to the belly; but if a female, the side of the abdomen must be shaven, and that part selected. From four to twenty-four leeches will be sufficient; and half that number may be again used if no change for the better is observed, and the strength does not fail. Stimulating applications are likewise beneficial. A large mustard poultice has appeared to be more operative than more violent agents. After it has been removed, warm fomentations of water, with occasional ones of hot turpentine, may be employed.
In the early stage, a warm bath of 90 degrees, for half an hour, has been used with advantage; but the animal, when removed from it, must be wrapped well up in several hot blankets, and kept in them until it is perfectly dry.
On the second day from two to ten drops of the tincture of arnica, with half a drachm of the solution of the chloride of zinc, may be added to the ethereal drinks and injections, if the disorder has not been checked; and beef-tea, thickened with rice, may also be frequently administered, using it instead of water, both in the draughts and injections. No other food is admissible, and the return to solids must, if the animal survives, be very gradual.
Dysentery and Diarrhœa. – These diseases, which in works on human pathology are advantageously separated, I cannot here treat of as distinct disorders. In the dog they are so connected and blended that the line which divides them cannot be discovered; and for every practical purpose, they may be here considered as one and the same affection.
The young and the old are most liable to these complaints. Puppies are very subject, as also are aged gross favorites; things so fat that it becomes hard work to live are very generally attacked with diarrhœa. The pup, however, usually exhibits it in the acute form, whereas in the other description of animal it mostly appears in the chronic type.
When acute, colic may accompany or precede it. In proportion to the spasm will be the violence and the danger of the disorder. Sickness is mostly witnessed a little time prior to the attack, and the matter vomited has a peculiarly disagreeable and acrid odor. The dog does not again consume that which the stomach has thrown off, but sneaks away dejected, and afterwards seems dull. Sickness will occasionally continue throughout the complaint, but in general it departs as the disease appears. Thirst, however, is always present; and there is also a disposition to seek cold things and places. The pulse is quicker, but not stronger, and hardly at first less thin than during health. There is no pain on pressure being applied to the abdomen. The membranes of the eye are not injected; they may be a little deeper in color than is strictly natural, but occasionally they are the reverse. If, however, the anus be gently forced open, so as to expose the terminating surface of the rectum, the membrane there will be found more red, and perhaps less clear in tint, than it ought to be; and the presence of purgation, attended with a violent resistance to the administration of clysters, will leave no doubt as to the character of the affection.
In the chronic form, the membrane of the eye is pallid; the nose often moist; the breath offensive; the appetite ravenous; the pulse quick and weak; the anus inflamed; mostly protruding, and usually disfigured by piles; the fæces liquid, and of various hues; sometimes black, occasionally lighter than usual, very generally mixed with much mucus and a small quantity of blood, so that the leading symptoms are those of weakness, accompanied with purgation.
