Powdered capsicums and cantharides have also seemed to touch the disease; but no one medicine has to me appeared to have any specific influence over it. In these cases mere formulæ could be extended almost indefinitely; but the reason must be exerted, and the prescription must be dictated by the symptoms. Thus, when there is much nervous excitability accompanied with gastric derangement, Prussic acid of Scheele's strength, in doses of half a drop to two drops, may be exhibited; and if the mouth be dry, and the disposition irritable, from five to twenty drops of the tincture of Indian tobacco may be administered. If the throat is very sore, the mouth may be held open, and ten grains of powdered alum mixed with four times its weight of fine sugar may be blown into it, or in severe instances, the fauces may be mopped out by means of a piece of soft sponge tied to the end of a probe, and saturated with a solution containing six grains of nitrate of silver dissolved in an ounce of water.
Ulceration of the interior of the larynx is to be dreaded if the symptoms do not yield. This will be denoted by the cough becoming weaker, less loud, more short, and also more frequent. Prior to it there are always intervals during which the animal enjoys repose; but after ulceration of the larynx is established every inhalation provokes the irritability of the organ. With it the constitutional symptoms become more serious, and little can then by medicine be accomplished; for the passage of the air which is necessary to life causes the affection we desire to cure to spread. Tracheotomy might be performed, though the dog is so very expert with its claws, and any tape around the neck would be probably so injurious, that hitherto I have not ventured to hazard the experiment. Humanity has, in such cases, forced me to recommend the destruction of the life which I entertained no hope of comforting.
Cough is much more frequently a symptom than a disease. It, in fat dogs, usually proceeds from disordered digestion; and then to remove it the cause must be attacked. It accompanies worms; and if these are expelled, it will subside. It may, however, exist by itself, for the larynx of the dog early becomes ossified or converted into bone; and being then less yielding, the violent vibrations it is subjected to during the act of barking have a natural tendency to injure the delicate lining membrane. Its irritability is excited, and cough is the consequence. The disposition of the creature to give tongue ought, therefore, to be as much as possible checked, and a mustard poultice applied to the throat, while the pills first recommended on page [205], are given; but if these fail, the others may be employed. The general measures would be pretty much the same, only the more severe need not be resorted to. Quiet, mild food, and a little care, will often, without medicine, remove the annoyance; but it is never well to trust too long to such dubious aids, when timely assistance will procure speedy relief, and delay may lead to further evil.
Snoring is often a heavy accusation brought against the dog. It may proceed from weakness; though, in ninety-nine cases out of every hundred, it results from that debility which accompanies accumulated fat and sloth. In the one case we apply the means advised to restore the strength,—in the other, we stint the food, enforce a vegetable diet, and see that sufficient exercise be taken.
Snorting is another unpleasantness which the canine race display. The animals stand with their heads erect, and, drawing the air through the nostrils, produce a series of harsh loud sounds, which are sometimes continued till the dog falls from actual exhaustion. This is the result of irritability, in a low form, of the lining membrane of the nasal chambers. The sensation is probably that of itching, and the dog endeavors, by drawing the air quickly through the nostrils and energetically expelling it, to relieve the annoyance.
The treatment is not to be laid down; attention to the food, and medicines of an alterative nature calculated to affect or improve the secretions, are most likely to be of service. Worms may possibly be the provocative, and in that case of course they should be removed. The measures, therefore, are not to be arbitrarily pointed out. The judgment must be employed to discover in what particular the system is unsound, and the agents used must be selected with a view to the general health. Local applications have been tried without advantage, but there do not appear to be any specifics for the complaint. The snorting is to be regarded merely as an effect of some deep-seated derangement, and the remedies are to be such as the appearance of the animal suggests. I have generally been successful in these cases, but I remember no two of them which I have treated exactly in the same manner. Patience and perseverance are mostly required, but sometimes the affection will not yield to any remedy. When it appears to be obstinate, the use of medicine should not be pushed too far. The constitution of the dog is so easily injured, and with so much difficulty restored, that where a mere unpleasantness is apparently all that exists, it is better to permit that to continue than hazard the health of the animal by over-strenuous attempts to get rid of it.
Cold or Coriza is not frequent in the dog, but it will occasionally be seen. It comes on gradually, and often passes off without any assistance being given. In pups it is apt to pass first into bronchitis, and then change into distemper, which in such instances, spite of our best endeavors, will often terminate in fits.
It springs from various causes, but neglect and improper lodging are generally those to which it may be traced. In adult animals it is not to be greatly feared, but in the young it requires immediate attention. The kennel must be looked to; the food and exercise be strictly watched. Tonics, into which cayenne pepper, cubebs, or balsam of pepper enter, are to be tried, and cod-liver oil also is worth an experiment. The iodide of potassium is also not to be rejected; but the condition of the patient must decide which is the most likely to be of service in the case. When undertaken early, the symptoms yield in the majority of instances. The discharge, which at the commencement is thin, becomes more copious, grows thicker, and at last ceases. The sneezing stops and the spirits return; but should the disorder not be checked, the larynx becomes involved, and cough appears. If no relief be now sought, and the disease spreads, the breathing grows quick at first, and then laborious.
The pup may even at this stage be eager to feed, and when its attention is excited, be as playful as in health; but if watched it will be seen, when alone, to be oppressed and languid. In such cases, belladonna, combined with James's powder, an equal amount of each, should be administered. The dose should be exhibited every hour, for here the wish is to obtain the speedy effect of the drug without allowing its sedative property to seriously affect the strength. To a young pup, a quarter of a grain will be the proper quantity; and for a full-grown large-sized dog, two grains of the extract may be employed. The action, however, must be observed, and when a marked disinclination for food or drink, with a seeming wish for both, and signs of inconvenience in the throat are seen, the belladonna must be withheld. On the third day, if the cure be not complete, it may be a second time employed; and, after a like period, even a further trial may be made. At the same time, a little soap liniment may be rubbed into the throat, along the course of the windpipe, and over the chest. The bowels also should be regulated; but purgation is not to be desired. Should the liver be sluggish, mild alterative doses of the grey powder may be sprinkled upon the food, and will thus be taken without the necessity of forcing the animal. When the measures recommended do not succeed, the appearance of the patient must direct those which are next to be adopted. Where weakness prevails, and shivering denotes the presence of fever, quinine and the sulphate of iron are required. Small blisters, or mustard poultices, to the chest, may with due caution be applied. An emetic may even be administered; but, if repeated at all, it must be only after two or three days have elapsed. Where the system is vigorous, expectorants and sedatives, with leeches to the chest, may be used. Turpentine liniment to the sides, throat, and under the jaws, may also be freely rubbed in, and the diet in quantity restricted. Tartar emetic in very minute doses may be exhibited three times daily.
