Commonly, after the second stage, there is an abatement of the symptoms, without any actual cessation in the discharges. The dog is concluded to be better, and thought to be doing well, but it will not be long before something to excite alarm is witnessed. The eyes or nerves, or lungs or liver, or stomach or intestines may be attacked; or a pustular eruption, or actual mange, or a disposition in the animal to eat its own flesh, or chorœa, or paralysis may appear, and all of these possible varieties require to be separately dwelt upon.
The eyes lose their transparency, the surface is white and opaque, the sight is impaired, and the lids are nearly constantly closed. One or both of the organs of vision may be thus affected; usually the two are simultaneously affected, but seldom with the like intensity. After a few days, and sometimes at the commencement, a small circular depression is to be seen upon the very centre of the eyeball. It is round, and varies in size from that of a pin's head to that of a small pea, but rarely becomes larger. The depression, if nothing be done to check it, deepens till a little shallow pit is exhibited. At other times the hole grows larger and deeper, till the outer covering of the eye is absorbed, or, in common phrase, is eaten through, and the water escapes: this gives relief. If, however, the animal survives, the eye is often perfectly restored, though very frequently a white speck marks the spot which was ulcerated; or the dog is left with weakened eyes, and has a tendency to cataract, which may ultimately render it blind.
The affection of the lungs is denoted by the dog breathing more quickly, and often making a small plaintive or whistling noise during respiration. Though cough is quite as often absent as present; but if present it is usually severe; the pulse is increased, but small and thready, and the appetite may not be impaired. The animal is, however, disinclined to move, if put down at liberty, it always gets into some place where it hopes to be allowed to remain undisturbed. As the symptoms become more intense, the animal constantly sits upon its haunches; but I have not seen it carry the head erect, although authors state this to be one of the indications. There is a desire for fresh air, and the dog will always leave the house, or get to the window or door, if he have an opportunity of so doing. These signs are hardly to be mistaken, but they are easily confirmed. If the ear be applied to the side of a healthy dog's chest, no sound can be detected; but when the lungs are diseased, a very plain noise is readily heard. The presence, therefore, of any murmur, or of anything like air escaping over a dry rough surface, is indicative of disease, and the certainty that the lungs are involved is confirmed.
Dogs of late years have not commonly died of pneumonia during the distemper; but authors speak of the pulmonary form of the disorder as having formerly been a common cause of death. I know it only as a mild variation of the ordinary symptoms. It has not in any case under my observation proved fatal, but has readily yielded to gentle measures, aided by attention to simple diet.
The liver is generally involved. After the termination of a fatal case, this gland is found either soft or more brittle than it ought to be, else it is discovered much enlarged. I never saw it of less than its natural size. Generally it is discolored, mostly of a pale tint; which sometimes exists all over the organ, though the pendulous edges of the lobes are very generally seen of the bright red, suggestive of inflammation. The gall-bladder is always distended with a thin dark-green fluid or impure bile; and a large quantity of the same secretion, but of greater consistency, is distributed over the lining membrane of the anterior intestines. The liver obviously is the cause of the yellow distemper, which is no more than jaundice added to the original and pre-existing disease. Yellow distemper is by writers treated of as a distinct disorder, but I have not yet met with it in that form. When it has come under my notice, it has been no more than one of the many complications which the symptoms are liable to assume. The dog has been ill before his skin became discolored; but the eyes not exhibiting that ordinary discharge which denotes the true character of the affection under which he labored, the distemper was not detected.
Everything concerning distemper is by the generality of the public misunderstood. Most people imagine a dog can have the distemper but once in its life; whereas I had a patient that underwent three distinct attacks in one autumn, that of 1849. The majority of persons who profess an intimate knowledge of the dog will tell you distemper is a disorder peculiar to the young; whereas I know of no age that is exempt from its attack. I have known dogs, high-bred favorites, to be left with men selected because of their supposed familiarity with dog diseases; and these very men have brought to me the animals in the fits which are the wind-up of distemper, yet notwithstanding have been ignorant that their charges had any disease whatever. All the stages and symptoms of ordinary distemper may appear and depart unnoticed; but it is widely different with yellow distemper, for when the yellowness appears, it is so marked that no description of a peculiar symptom need be inserted, since it cannot be overlooked or mistaken. It is attended with excessive debility, and, unless properly combated, is rapidly fatal.
The stomach and intestines are always involved; I have never known a case in which either escaped. The affection of the first is generally shown by sickness during the earliest stage; when also the derangement of the last is denoted by either costiveness or relaxation, the bowels never being perfectly regular; towards the latter stages, or about the third or fourth week, the appetite sometimes becomes enormous; the craving for food is then unnatural, and is so intense that no quantity can appease the hunger. The animal will eat anything; dry bread is taken with avidity, and stones, cinders, straw, and every species of filth are eaten with apparent relish. Such, however, is not always the case, since it is not unusual for the appetite entirely to fail. In either instance the dog rapidly wastes; the flesh seems to melt as it were away, and the change produced by a few days is startling; from having been fat, a thinness which exposes every bone is witnessed in a shorter time than would be supposed possible. At this period vomiting may come on; but when the animal is morbidly ravenous, the stomach does not generally reject its contents. After death I have found it loaded with the most irritating substances, and always acutely inflamed; but no sickness in any instance of this kind has been observed. Vomiting is most generally absent, but the protruded and reddened appearance of the anus will give a clue to the actual condition of the alimentary tube. The stomach is inflamed, not throughout, but in various parts which are in different stages of disease. The pyloric orifice is always more affected than the cardiac; the duodenum, jejunum, and ileum, are inflamed; the cæcum is enlarged, inflamed, and generally impacted. The rectum, however, suffers most severely; it is much reddened and thickened, often to an extraordinary degree. I have known blood to be exuded from the surface of this bowel in such quantities as to destroy the life from actual hemorrhage. In one case, however, a spaniel vomited more than half-a-pint of blood previous to its death, which took place two hours afterwards. A small quantity of blood is ordinarily passed with the fæces toward the latter stage; but in several cases a large amount of pure blood, partly coagulated and unmingled with any fæcal matter, has flowed from the body in a continued stream, to which there will be cessation only as death approaches. The possibility of this
