such measures as he concludes are adapted to the symptoms, and waits for further instructions which nature will speedily develope.
When the disease is established, the animal is sensitive to cold. It seeks warmth, and is constantly shivering; when taken hold of, it is felt to tremble violently, so much so that the pulse cannot be accurately counted. The bowels are generally constipated. A thick purulent discharge flows from the eyes; and the white around the eye, if the upper lid be retracted, will be seen covered with numerous small and bright red vessels, giving to the part the appearance of acute inflammation. The vessels now spoken of are not to be confounded with the veins which are natural to this organ. These last are large, and of a purple hue, while their course is in the direction of the circumference of the cornea. The small vessels, indicative of distemper, are fine, bright in color, and their course is towards the centre, or in a line directly the opposite to that indicated by the veins. They are never present during health, though they are often to be witnessed in other diseases besides that which is here treated of. A glairy mucus, or yellow fluid, moistens the nostrils, and if the ear be applied to the head, the breathing will be discovered to be accompanied with an unusual sound. The cough is often severe and frequent; it is sometimes spasmodic – the fits being almost convulsive, and terminating with the ejection of a small quantity of yellow frothy liquid, which is thrown off by the stomach. The digestion is always impaired, and sickness is not unusual; the matter vomited having an offensive smell, and never being again consumed by the animal, as is generally the case when the creature is in health. The nose is dry and harsh; the coat staring and devoid of gloss: the skin hotter than is customary, and the paws warm. The pulse is perhaps quicker by twenty beats than during the prior stage, but less full – the artery feeling sharp, short, and thin under the finger.
When the symptoms described are apparent, the distemper is easily recognised, but it is not likely to continue stationary for any long period. In the course of a week it generally changes its character, and sometimes appears to subside altogether; the cases in which the disease steadily progresses, becoming day by day more severe, being comparatively rare.
When no abatement is witnessed, the case is not to be despaired of, but it requires to be anxiously watched; for often it will take a sudden turn, sometimes favorable, but more frequently demanding immediate assistance to prevent a fatal termination. The symptoms become aggravated. The eyes are clogged by a thick matter which glues the lids together, especially in the morning. The nostrils are plugged up by an accumulation of tenacious discharge, which becomes encrusted over the lips and nose, and impedes the breathing. The body rapidly wastes, though the appetite may return, and even be voracious. The shivering is constant. The dog seeks repose and is disinclined to move; though at times it may be playful, and in some instances will never exhibit any diminution of spirit. The cough may continue; but it more often ceases, or is only heard at irregular and distant intervals. The animal makes repeated and desperate efforts to expel the accumulated matter from the nose, and uses its paws evidently with an intention to remove the annoyance. Day by day, if not attended to, these signs grow more aggravated; the breath becomes very offensive; ulcers appear on the lips; the eyes become white; the discharge from the nostrils changes its color, and is mingled with blood and scabs, having an offensive odor. The creature at last begins to "yap," or utter short sharp cries. It becomes more weak, till at length it cannot walk, but lies upon its side; the noise being continued for hours, and then ceasing only to be again commenced. Constipation has usually been present, but at last diarrhœa sets in; the fæces have that peculiar smell which in the dog is characteristic of the latest stage of all; and gradually death, without a seeming struggle, closes the scene of suffering.
More frequently – indeed, in the majority of cases – the distemper is hardly well developed before it all at once seems to disappear. This peculiarity in the disorder has no doubt given strength to the general faith in specifics for this disease. The animal suddenly so far recovers, or appears to recover, after having been seriously affected, that the inexperienced naturally conclude the dog is either quite well, or evidently so far cured that the efficacy of the remedy administered is not to be disputed. For two or three weeks this deceptive appearance may continue, and in some cases no return of the symptoms may be witnessed; but in the majority of instances the disorder is only dormant, and again starts up as if it had been strengthened by its treacherous repose. The running from the nose comes back in excessive quantities, and either the bowels are singly inflamed, or with them the brain is involved, and fits or diarrhœa, or both united, speedily terminate in death, to arrest which medicine has seldom the power. The loss is on these occasions rarely attributed to distemper, which is thought to have been subdued; but death is commonly set down to fits, or to poison, or to inflammation of the bowels, or to anything else which the imagination of the proprietor may conceive. Hence we get an insight into the value of a large number, and perhaps into all, of the reputed nostrums; and hence it is the more necessary the reader should be made aware of those indications which denote the virus is not eradicated, but only latent as it were, lurking, to spring with greater certainty upon its victim. No one must conclude the distemper is mastered if the dog continues to lose flesh, or if the animal does not rapidly repair the waste consequent upon the earlier stages of the disorder. This tendency to stand still or decline should be carefully observed, and it will seldom deceive. When it is remarked, or even suspected, let the owner be upon his guard. When the distemper is actually overcome, there is a marked disposition to fatten; indeed, so strong is it at this time that, should it not be evident, there can be no doubt as to the cause, especially if a short and slight attack of the disorder has been known to have occurred a little time before. A warning, equally clear to those who will look for and can read it, is to be obtained from the eyes. These may be bright, and even peculiarly transparent; the face have a more animated expression than it displayed during previous health; but if the eyelids are retracted, the membranes will be found red, and the vessels before observed upon will be seen running over the white of the eye. When these things are present, although the coat may be beautifully smooth, the discharge dried up, the shivering gone, the appetite strong, and the spirits boisterous, still there is in the system the seeds of a disease which at no distant period will reappear in its most dangerous form.
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.
