chorea
which I have mentioned as an occasional sequel of distemper, if the dog is in tolerable condition, and especially if he is gaining flesh, and the spring or summer is approaching, there is a chance of his doing well. A seton is the first thing; the bowels should be preserved from constipation; and the nitrate of silver, in doses of one-eighth of a grain, made into a pill with linseed meal, and increased to a quarter of a grain, should be given morning and night.
We should never make too sure of the recovery of a distempered dog, nor commit ourselves by too early a prognosis. It is a treacherous disease; the medicines should be continued until every symptom has fairly disappeared; and for a month at least.
may be interesting to add the following account of the distemper in dogs, by Dr. Jenner. Several of our modern writers have copied very closely from him.
"That disease among dogs which has familiarly been called the distemper, has not hitherto, I believe, been, much noticed by medical men. My situation in the country favouring my wishes to make some observations on this singular malady, I availed myself of it, during several successive years, among a large number of foxhounds belonging to the Earl of Berkeley; and, from observing how frequently it has been confounded with hydrophobia, I am induced to lay the result of my inquiries before the Medical and Chirurgical Society. It may be difficult, perhaps, precisely to ascertain the period of its first appearance in Britain. In this and the neighbouring counties, I have not been able to trace it back beyond the middle of the last century; but it has since spread universally. I knew a gentleman who, about forty-five years ago, destroyed the greater part of his hounds, from supposing them mad, when the distemper first broke out among them; so little was it then known by those most conversant with dogs. On the continent I find it has been known for a much longer period; it is as contagious among dogs as the small-pox, measles, or scarlet fever among the human species; and the contagious miasmata, like those arising from the diseases just mentioned, retain their infectious properties a long time after separation from the distempered animal. Young hounds, for example, brought in a state of health into a kennel, where others have gone through the distemper, seldom escape it. I have endeavoured to destroy the contagion by ordering every part of a kennel to be carefully washed with water, then whitewashed, and finally to be repeatedly fumigated with the vapour of marine acid, but without any good result.
"The dogs generally sicken early in the second week after exposure to the contagion; it is more commonly a violent disease than otherwise, and cuts off at least one in three that are attacked by it. It commences with inflammation of the substance of the lungs, and generally of the mucous membrane of the bronchi. The inflammation at the same time seizes on the membranes of the nostrils, and those lining the bones of the nose, particularly the nasal portion of the ethmoid bone. These membranes are often inflamed to such a degree as to occasion extravasation of blood, which I have observed coagulated on their surface. The breathing is short and quick, and the breath is often fetid; the teeth are covered with a dark mucus. There is frequently a vomiting of a glairy fluid. The dog commonly refuses food, but his thirst seems insatiable, and nothing cheers him like the sight of water. The bowels, although generally constipated as the disease advances, are frequently affected with diarrhœa at its commencement. The eyes are inflamed, and the sight is often obscured by mucus secreted from the eyelids, or by opacity of the cornea. The brain is often affected as early as the second day after the attack; ihe animal becomes stupid, and his general habits are changed. In this state, if not prevented by loss of strength, he sometimes wanders from his home. He is frequently endeavouring to expel by forcible expirations the mucus from the trachea and fauces, with a peculiar rattling noise. His jaws are generally smeared with it, and it sometimes flows out in a frothy state, from his frequent champing.
"During the progress of the disease, especially in its advanced stages, he is disposed to bite and gnaw anything within his reach; he has sometimes epileptic fits, and a quick succession of general though slight convulsive spasms of the muscles. If the dog survive, this affection of the muscles continues through life. He is often attacked with fits of a different description; he first staggers, then tumbles, rolls, cries as if whipped, and tears up the ground with his teeth and fore feet: he then lies down senseless and exhausted. On recovering, he gets up, moves his tail, looks placid, comes to a whistle, and appears in every respect much better than before the attack. The eyes, during this paroxysm, look bright, and, unless previously rendered dim by mucus, or opacity of the cornea, seem as if they were starting from their sockets. He becomes emaciated, and totters from feebleness in attempting to walk, or from a partial paralysis of the hind legs. In this state he sometimes lingers on till the third or fourth week, and then either begins to show signs of returning health (which seldom happens when the symptoms have continued with this degree of violence), or expires. During convalescence, he has sometimes, though rarely, profuse hæmorrhage from the nose.
"When the inflammation of the lungs is very severe, he frequently dies on the third day. I know one instance of a dog dying within twenty-four hours after the seizure; and in that short space of time the greater portion of the lungs was, from exudation, converted into a substance nearly as solid as the liver of a sound animal. In this case the liver itself was considerably inflamed, and the eyes and flesh universally were tinged with yellow, though I did not observe anything obstructing the biliary ducts. In other instances I have also observed the eyes looking yellow.
"The above is a description of the disease in its several forms; but in this, as in the diseases of the human body, there is every gradation in its violence.
"There is also another affinity to some human diseases, viz., that the animal which has once gone through it very rarely meets with a second attack. Fortunately this distemper is not communicable to man. Neither the effluvia from the diseased dog nor the bite have proved in any instance infectious; but, as it has often been confounded with canine madness, as I have before observed, it is to be wished that it were more generally understood; for those who are bitten by a dog in this state are sometimes thrown into such perturbation that hydrophobia symptoms have actually arisen from the workings of the imagination. Mr. John Hunter used to speak of a case somewhat of this description in his lectures.
"[A] gentleman who received a severe bite from a dog, soon after fancied the animal was mad. He felt a horror at the sight of liquids, and was actually convulsed on attempting to swallow them. So uncontrollable were his prepossessions, that Mr. Hunter conceived he would have died had not the dog which inflicted the wound been found and brought into his room in perfect health. This soon restored his mind to a state of tranquillity. The sight of water no longer afflicted him, and he quickly recovered."[2]
, more or less complete, is sometimes the termination of the distemper in dogs.
It is usually accompanied by chorea, and it is then, in the majority of cases, hopeless. Setons should be inserted in the poll, being then, as nearly as possible, at the commencement of the spinal cord. They should be well stimulated and worn a considerable time. If they fail, a plaster composed of common pitch, with a very small quantity of yellow wax and some powdered cantharides, spread on sheep's-skin, should be placed over the whole of the lumbar and sacral regions, extending half-way down the thigh on either side. The bowels should be kept open by mild aperients, in order that every source of irritation may be removed from the intestinal canal. Some mild and general tonic will likewise be useful, such as gentian and ginger.
