GENERAL REMARKS
There is no animal so widely distributed as the dog. The like assertion could not be made of any other domesticated creature. In countries subjected to the extremes of heat or cold, in the centre of Africa, and at the Northern Pole, the horse is absent; but wherever man is able to exist, there, in some shape or other, the dog is represented. Various have been the speculations as to its original. There is no animal in any way approaching in outward appearance to the Canine Species (properly so called), but has been assumed to be the original parent of the family. Some have even fancied the fox was father to all the dogs that trot by the side of man; but this idea seems too preposterous to be maintained. Others, with more reason, have supposed the prototype of the dog was discovered in the wolf. There are, however, many differences to reconcile before this hypothesis can be received. The formation of the two animals is distinct, – their anatomy presents positive differences, – their time of breeding does not agree, – their habits are opposite, and their outward and inward character is entirely dissimilar. The above engraving is the portrait of the wolf. Is the reader in any danger of mistaking it for that of a dog?
Thus the apparent separation of the two species appears to be so wide, that a child could point it out, and none but a philosopher could confound it. Others, again, have gone to warmer climates for the founder of the kind, which they have, to their own satisfaction, discovered in the jackal: but there are very many obstacles to be surmounted, before this supposition can be acknowledged. In the first place, although the dog is to be found in warm climates, he thrives least in those to which the jackal is entirely confined. Then all that has been urged against the fancy which conceived the prototype of the dog was to be found in the wolf, applies with even greater force to the jackal. However, to settle the dispute, we here give the likeness of the beast, and leave to the reader to point out the particular breed of dogs to which it belongs.
Beyond the circumstance of the habitats of the animals being distinct, is the well-known fact that all domesticated animals have a disposition to return to their original formation; but who ever heard of a dog, however neglected, or however wild, becoming either a wolf or a jackal?
The dog is spread all over the world, and not only is the animal thus widely distributed over the face of the earth, but there is no creature that is permitted with such perfect safety to the human race to have such continual and intimate intercourse with mankind. It is found in every abode: the palace, the warehouse, the mansion, and the cottage, equally afford it shelter. No condition of life is there with which the dog is not connected. The playmate of the infant, the favorite of the woman, the servant of the man, and the companion of the aged, it is seen in and around every home.
Thus brought into intimate connexion with the human race, and continually subject to observation, it is not a little strange that the dog should be universally misunderstood. There is no quadruped which is more abused; whether treated kindly or otherwise, the dog is equally made to suffer; and probably the consequences of over indulgence are more cruel in their result than is the opposite course of treatment. The health of the beast is perhaps best preserved when neglect deprives it of man's attention; then it may suffer from want, but it escapes many of the diseases which caprice or ignorance entail upon the generality of the tribe. There exists no creature more liable to disorder, and in which disease is prone to assume a more virulent or a more complicated form. To minister to its afflictions, therefore, demands no inconsiderable skill; and it becomes the more difficult to alleviate them, since canine pathology is not fully comprehended, nor the action of the various medicines upon the poor beast clearly understood; yet there are few persons who in their own estimation are not able to vanquish the many diseases to which the dog is liable. About every stable are to be met crowds of uneducated loiterers, possessors of recipes and owners of specifics, eager to advise and confident of success. I seldom send a diseased dog into the park for exercise, that my servant does not return to me with messages which strangers have volunteered how to cure the animal. I hear of medicines that never fail, and of processes that always afford relief. Persons often of the upper rank honor me with secret communications which in their opinion are of inestimable value; ladies frequently entreat me to try particular nostrums, and sportsmen not seldom command me to do things which I am obliged to decline. In fact, the man who shall attempt to treat the diseases of the dog, will have no little annoyance to surmount. He will soon discover that science unfortunately can afford him but partial help, while prejudice on every side increases the difficulties with which he will have to contend.
Happily, however, the majority of pretended cures are harmless. A roll of sulphur in the animal's water may be permitted, since it amuses the proprietor while it does not injure his dog. Some of these domestic recipes, nevertheless, are far from harmless, and they are the more to be deprecated, because those which most people would imagine to be safe are the very ones which are attended with the greatest danger. Common salt is a poison to the dog; tobacco is the source of many a death in the kennel; castor oil often does the ill which months of care are needed to efface, even if the life be not destroyed. In the majority of cases vomits are far from beneficial; bleeding is very seldom required, and the warm bath has sealed the doom of innumerable animals.
The foregoing observations will have informed the reader of the reasons that prompt the publication of the present work, which is put forth only as a step towards the point the author does not yet pretend to have fully attained. The study of years will be required to perfect that which is now commenced, and further experience will probably demand the retraction of many of the opinions herein advanced. The reader will understand, the author in the present work asserts only that which he now believes. It must not be imagined, however positive may read the language in which his sentiments are expressed, that the writer is pledged to uphold any of the conclusions at which he may have arrived; knowledge is in its nature progressive, and canine pathology is not yet clearly made out. The advantages which accompany the study of anatomy, physiology, and therapeutics have yet to be more largely applied to the diseases of the dog, and until this has been accomplished, science, not reposing upon truth, will be constantly subjected to change. The present work, therefore, will be accepted only as a contribution to veterinary literature, and its contents will be viewed as doing nothing more than declaring the temporary convictions of one, who, desirous of truth, does not conceal that his mind is oppressed by many doubts.
In the following pages advantage will be freely taken of the labours of those authors who have written upon the subject; nor must it be supposed, because the writer may feel himself obliged to dissent from, he therefore undervalues the genius of Blaine or Youatt. Before Blaine collected and arranged the knowledge which existed concerning the diseases of the dog, canine pathology, as a separate or distinct branch of veterinary science, hardly existed. The task he accomplished; but if after the lapse of years some of his opinions are found to be unsound, and some of his statements discovered to require correction, these circumstances may be regarded as the natural consequences of progression, while they in no way deteriorate from the honor due to his name. Youatt enlarged and softened the teaching of his master, and by the liberality of his communications, and the gentleness of his example, improved and adorned the science to which he was attached. To others than these two great men I have no obligations to acknowledge. For their memories I take the opportunity of expressing the highest respect, and confess that to their instruction is fairly due any novelty which the present pages may contain; since but for those advantages their teaching afforded, it is more than doubtful if I had perceived the facts herein made known.
Before any mention is made of the diseases of the dog, it will be proper to take some notice of the temperament of the animal, as without regarding this the best selected medicines, or the most assiduous attention, may be of no avail. Any one who will observe the animal will soon be made aware of its excessive irritability. The nervous system in this creature is largely developed, and, exerting an influence over all its actions, gives character
