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.
