Lice often cover the body of the dog, and especially crowd upon its head around the eyes and lips. There need be no dread of their presence, since these vermin will not live upon the human being, though similar to the kind which will. When they are perceived, the dog should be carried into some place in which grease stains are not of much consequence. It ought then to be covered with castor oil till the hair is completely saturated. In this state it should be allowed to remain at least twelve hours, at the expiration of which time the oil may be removed with yelk of eggs and water: only an additional number of eggs will be required. As to the quantity of castor oil which may be necessary, a moderate-sized dog with a long coat will require about a pound, and a large Newfoundland four times that amount. The process, as might be anticipated, operates upon the bowels; but I have never found it to do so with any dangerous power; on the contrary, the laxative effect is generally in these cases beneficial.
Medicine to the dog requires to be administered with caution. The nostrums which are so particularly recommended by grooms and farriers ought never to be made use of. The veterinary surgeon is less likely to commit error; but there are, however, few of the profession who devote attention to the dog with the zeal which the comprehension of its diseases and their treatment demand. Huntsmen and gamekeepers are generally from practical experience not altogether inapt dog doctors, where the larger and more robust kind of animal is to be treated, but for the smaller and petted species these persons ought not to be consulted. Many of their receipts are harsh – not a few of them inoperative – and some even dangerous; while all for the most part are pushed down at random, or in total ignorance of any effect the agents employed may induce beyond the intended one of doing good or working a certain cure. Nevertheless, with the kind of animals generally entrusted to their charge, such persons are so far successful that, in the absence of better advice, they deserve to be consulted for the larger species of dogs. The human physician will also, on occasions, be enabled to prescribe advantageously for the canine race; but not knowing the treatment of the diseases, and the symptoms being too often deceptive, the highest opinions are by no means to be absolutely relied upon.
Dog-doctoring is, in fact, a separate branch of science so intricate as to call for intense study strengthened by constant observation. No one not attached to the animal should attempt to master it, for success in such a case would be hopeless. The annoyances are so great that the patience is continually being tried; and the facts on which reliance can be placed are so few, that he who is content to depend upon the received assertions will never be able to realize his expectation. Nothing is more erroneous than to believe that there is any close analogy between man and the dog in the operation of medicinal substances. Aloes, rhubarb, &c., are not purgatives to the dog; but castor oil, which to the human being is a gentle laxative, to the dog is an active purge; while Epsom salts are a violent hydragogue to the canine patient, producing copious and watery stools. Common salt is in large doses a poison, and in apparent small quantities is so strong an emetic as to be dangerous. Salivation speedily ensues upon the use of minute quantities of mercury, which therefore cannot be considered safe in the hands of the general practitioner. Secale cornutum has little specific action beyond that of inducing vomiting; and strychnia cannot be with security administered, on account of its poisonous operation upon the animal. Other instances, casting more than suspicion upon the inferences which every writer upon Materia Medica draws from the action of drugs given to dogs, could easily be quoted, but they would here be somewhat out of place; and probably sufficient has been said to check a dangerous reliance upon results that admit of no positive deduction.
It is painful to peruse the "experiments" made especially by the French authors. We read that so much of some particular agent caused death to a dog in such a period; but he must be wise indeed who learns anything from statements of this kind. The word dog represents animals of various sizes and very diverse constitutions; therefore no conclusion can be drawn from an assertion that does not embrace every particular. Unfortunately, however, the operators think it no disgrace to their scientific attainments to put forth such loose and idle assertions; nor do they seem to hold it derogatory to their intelligence that they assume to reach a show of certainty by experimentalising upon a creature about which, as their reports bear witness, they literally know nothing. Equally unsatisfactory are the surgical and physiological experiments made upon these creatures. No results deduced from such acts can be of the slightest importance. The anatomy of the dog is not by them generally understood. There is no book upon this subject that is deserving of commendation; and, to instance the ignorance which prevails even in places where a superficial knowledge ought to exist, I will mention but one circumstance.
At the Royal Veterinary College there is a professor of Particular Anatomy, whose duty it is specially to instruct the pupils concerning the dog. The lectures, however, embrace but little, and that little is principally devoted to wandering remarks upon the osseous structure. Of the value of such teaching some opinion may be formed when the skeleton at the College actually exhibits the bones placed in wrong or unnatural situations. After the proof thereby afforded, with what reliance can any sane mind accept the awful declarations of those anatomists who, upon the living bodies of these creatures, have, according to their own accounts, exhibited a nicety and certainty of skill which the profoundest acquaintance with the various structures and parts would still leave incomprehensible? Such reports evidence only the presumptuous folly of individuals – the publication of such records testifies no more than the ignorance of the age.
To give medicine to the Dog often creates more bustle than the magnitude of the creature appears to justify. Moreover, if the parties concerned in the undertaking are not quite up to their business, the animal, which, between its gasping, howling, and struggling, will find time to bite, increases the activity by provoking human exclamations. I have known this species of confusion to have been continued for half an hour; during which work was stopped in a forge, and three brawny smiths joined a veterinary surgeon's efforts to give a pill to a little spaniel that could not have weighed above eight pounds. The dog was beaten and hands were bitten, but after all no pill was swallowed. The result was the natural consequence of the manner of proceeding. No man should contend with an animal, and especially with a dog, whose excitement soon renders it incapable of obedience.
With brutes of every kind, if the mastery cannot, by a bold stratagem, be gained at once, it should be only established through the confidence of the animal, which a few acts of kindness will, in the majority of cases, easily win. I have had dogs brought to me which seemed disposed rather to part with life than permit their jaws to be handled. The poor beasts had been harshly used by the persons who had previously undertaken to treat them. These creatures have remained with me, and in a little time have grown so submissive that my shop-boy could with ease give any kind of physic which I ordered to be prepared. Firmness and kindness were the only stratagems I employed. I took care never to give the dog a chance of mastery, but while ensuring my victory, I was careful that the conquest caused no sense of pain. A few pats, with a kind word, and an occasional reward in the shape of a bit of meat, induced the creature more willingly to submit when the next dose came round.
A small dog should be taken into the lap, the person who is to give the physic being seated. If the animal has learned to fight with its claws, an assistant must kneel at the side of the chair and tightly hold them when the dog has been cast upon its back. The left hand is then made to grasp the skull, the thumb and fore finger being pressed against the cheeks so as to force them between the posterior molar teeth. A firm hold of the head will thus be gained, and the jaws are prevented from being closed by the pain which every effort to shut the mouth produces. No time should be lost, but the pill ought
