This is a permanent character, not affected, as far as is at present known, by any artificial or natural circumstances to which the dog has been subjected. Naturalists, therefore, have seized upon this character as the ground for a division of animals of the dog kind, the great genus Canis of Linnæus, into two groups, the diurnal and nocturnal; not to imply that these habits necessarily belong to all the individuals composing either of these divisions, for that would be untrue, but simply that the figure of the pupils corresponds with that frequently distinguishing day-roaming animals from those that prowl only by night. It is remarkable that a more certain and serviceable specific distinction is thus afforded by a little anatomical point, than by any of the more obvious circumstances of form, size, or colour. Whether future researches into the minute structure of animals may not discover other means to assist the naturalist in distinguishing nearly allied species, is a most important subject for inquiry, which cannot be entertained here. But to encourage those who may be disposed to undertake it, I must mention the curious fact, that the group to which the camel belongs is not more certainly indicated by his grotesque and singular figure than by the form of the red particles which circulate in his blood. And here again the inherent interest of the matter will lead me to enter a little into particulars, which may engage any one who has a good microscope in a most instructive course of observations, not the least recommendation of which is, that a just and pleasing source of recreation may be thus pursued by evening parties in the drawing-room, since the slightest prick of the finger will furnish blood enough for a microscopic entertainment, and you may readily procure a little more for comparison from any animal.
Now the redness of the blood is owing to myriads of minute objects in which the colour of the vital fluid resides. They were formerly called globules, but as they are now known to be flattened and disc-like, they are more properly termed particles or corpuscles. Their form is wonderfully regular, and so is their size within certain limits; in birds, reptiles, or fishes, the corpuscles are oval. They are circular in man, and all other mammalia, except in the camel tribe, in which the corpuscles are oval, though much smaller than in the lower animals. Thus, in the minutest drop of blood, any one of the camel family can be surely distinguished from all other animals, even from its allies among the ruminants; and what is more to our purpose, in pursuing this inquiry, Mr. Gulliver has found that the blood-corpuscles of the dog and wolf agree exactly, while those of all the true foxes are slightly though distinctly smaller.
These curious facts are all fully detailed in Mr. Gulliver's Appendix to the English version of Gerber's Anatomy, but I think that they are now for the first time enlisted into the service of Natural History.
Thus we dismiss the fox as an alien to the dog, or, at all events, as a distinct species. Then comes the claim of the wolf as the true original of the dog. Before considering this, let us revert to the question of what constitutes a species. Mr. Hunter was of opinion that it is the power of breeding together and of continuing the breed with each other; that this is partially the case between the dog and the wolf is certain, for Lord Clanbrassil and Lord Pembroke proved the fact beyond a doubt, above half-a-century ago; and the following epitaph in the garden at Wilton House is a curious record of the particulars:--
Here lies Lupa, Whose Grandmother was a Wolf, Whose Father and Grandfather were Dogs, and whose Mother was half Wolf and half Dog. She died on the 16th of October, 1782, Aged 12 years.
Conclusive as this fact may appear, as proving the descent of the dog from the wolf, it is not convincing, the dog having characters which do not belong to the wolf.
The dog, for instance, guards property with strictest vigilance, which has been entrusted to his charge; all his energies seem roused at night, as though aware that that is the time when depredations are committed. His courage is unbounded, a property not possessed by the wolf: he appears never to forget a kindness, but soon loses the recollection of an injury, if received from the hand of one he loves, but resents it if offered by a stranger. His docility and mental pliability exceed those of any other animal; his habits are social, and his fidelity not to be shaken; hunger cannot weaken, nor old age impair it. His discrimination is equal, in many respects, to human intelligence. If he commits a fault, he is sensible of it, and shows pleasure when commended. These, and many other qualities, which might have been enumerated, are distinct from those possessed by the wolf. It may be said that domestication might produce them in the latter. This may be doubted, and is not likely to be proved; the fact is, the dog would appear to be a precious gift to man from a benevolent Creator, to become his friend, companion, protector, and the indefatigable agent of his wishes. While all other animals had the fear and dread of man implanted in them, the poor dog alone looked at his master with affection, and the tie once formed was never broken to the present hour.
It should also be mentioned, in continuation of my argument, that the experiment of the wolf breeding with the dog is of no value, because it has never been carried sufficiently far to prove that the progeny would continue fertile inter se. The wolf has oblique eyes--the eyes of dogs have never retrograded to that position. If the dog descended from the wolf, a constant tendency would have been observed in the former to revert to the original type or species. This is a law in all other cross-breeds--but amongst all the varieties of dogs, this tendency has not existed. I may also add, that as far as I have been able to ascertain the fact, the number of teats of the female wolf have never been known to vary. With respect to the dog, it is known that they do vary, some having more, and others a less number.
Having thus brought forward such arguments as have occurred to me to prove that the dog is a breed sui generis, I will give a few anecdotes to show how different this animal is in his specific character to the wolf, and that he has a natural tendency to acknowledge man as his friend and protector, an instinct never shown by the wolf.
In Ceylon there are a great number of what are called wild dogs, that is, dogs who have no master, and who haunt villages and jungles, picking up what food they are able to find. If you meet one of these neglected animals, and only look at him with an expression of kindness, from that moment he attaches himself to you, owns you for his master, and will remain faithful to you for the remainder of his life.
"Man," says Burns, "is the God of the dog; he knows no other; and see how he worships him! With what reverence he crouches at his feet, with what reverence he looks up to him, with what delight he fawns upon him, and with what cheerful alacrity he obeys him!"
Such is the animal which the brutality of man subjects to so much ill-treatment; its character depends very much on that of his master, kindness and confidence produce the same qualities in the dog, while ill-usage makes him sullen and distrustful of beings far more brutal than himself.
I have had many opportunities of observing how readily dogs comprehend language, and how they are aware when they are the subject of conversation. A gentleman once said in the hearing of an old and favourite dog, who was at the time basking in the sun,--"I must have Ponto killed, for he gets old and is offensive." The dog slunk away, and never came near his master afterwards. Many similar anecdotes might be brought forward, but I will mention one which Captain Brown tells us he received himself from Sir Walter Scott.
"The wisest dog I ever had," said Sir Walter, "was what is called the bulldog terrier. I taught him to understand a great many words, insomuch that I am positive that the communication betwixt the canine species and ourselves might be greatly enlarged. Camp once bit the baker, who was bringing bread to the family. I beat him, and explained the enormity of his offence; after which, to the last moment of his life, he never heard the least allusion to the story, in whatever voice or tone it was mentioned, without getting up and retiring into the darkest corner of the room, with great appearance of distress. Then if you said, 'the baker was well paid,' or, 'the baker was not hurt after all,' Camp came forth from his hiding-place, capered, and barked, and rejoiced. When he was unable, towards the end of his life, to attend me when on horseback, he used to watch for my return, and the servant would tell him 'his master was coming down the hill, or through the moor,' and although he did not use any gesture to explain his meaning, Camp was never known to mistake him, but either went out at the front to go up the hill, or at the back to get down to the moor-side. He certainly had a singular knowledge of spoken language." An anecdote from Sir Walter Scott must be always pleasing.
Mr. Smellie, in his "Philosophy of Natural History," mentions a curious instance of the intellectual faculty of a dog. He states that "a grocer in Edinburgh had one which for some time amused and astonished the people in the neighbourhood. A man who went through the streets ringing a bell and selling pies, happened one day to treat this dog with a pie. The next time he heard the pieman's bell he ran impetuously toward him, seized him by the coat, and would not suffer him to pass. The pieman, who understood what the animal wanted, showed him a penny, and pointed to his master, who stood at the street-door, and saw what was going on. The dog immediately supplicated his master by many humble gestures and looks, and on receiving a penny he instantly carried it in his mouth to the pieman, and received his pie. This traffic between the pieman and the grocer's dog continued to be daily practised for several months."
The affection which some dogs show to their masters and mistresses is not only very often surprising, but even affecting. An instance of this lately occurred at Brighton. The wife of a member of the town council at that place had been an invalid for some time, and at last was confined to her bed. During this period she was constantly attended by a faithful and affectionate dog, who either slept in her room or outside her door. She died, was buried, and the dog followed the remains of his beloved mistress to her grave. After the funeral the husband and his friends returned to the house, and while they were partaking of some refreshment the dog put its paws on his master's arm, as if to attract his attention, looked wistfully in his face, and then laid down and instantly expired.
In giving miscellaneous anecdotes in order to show the general character of the dog, I may mention the following very curious one.
During a very severe frost and fall of snow in Scotland, the fowls did not make their appearance at the hour when they usually retired to roost, and no one knew what had become of them; the house-dog at last entered the kitchen, having in his mouth a hen, apparently dead. Forcing his way to the fire, the sagacious animal laid his charge down upon the warm hearth, and immediately set off. He soon came again with another, which he deposited in the same place, and so continued till the whole of the poor birds were rescued. Wandering about the stack-yard, the fowls had become quite benumbed by the extreme cold, and had crowded together, when the dog observing them, effected their deliverance, for they all revived by the warmth of the fire.
That dogs possess a faculty nearly allied to reason cannot, I think, be doubted. Mr. Davy, in his "Angler in the Lake District," (a charming work), gives one or two anecdotes in proof of this.
When Mr. Davy was at Ceylon, the Governor of that Island, the late Sir Robert Brownrigg, had a dog of more than ordinary sagacity. He always accompanied his master, being allowed to do so, except on particular occasions, such as going to church or council, or to inspect his troops, when the Governor usually wore his sword; but when the dog saw the sword girded on, he would only follow to the outer door. Without a word being said, he would return and wait the coming back of his master, patiently remaining up-stairs at the door of his private apartment. So it is with respect to my own pet terrier, Phiz. When he sees me putting on my walking-shoes, my great-coat, or hat, he is all eagerness to accompany me, jumping about me and showing his joy. But on Sundays it is very different. My shoes, great-coat or hat, may be put on, but he remains perfectly resigned on the rug before the fire, and never attempts or shows any inclination to follow me. Is the dog guided in acting thus by instinct or reason?
Let me give another instance from Mr. Davy's work.
Once when he was fishing in the highlands of Scotland, he saw a party of sportsmen, with their dogs, cross the stream, the men wading, the dogs swimming, with the exception of one, who stopped on the bank piteously howling. After a few minutes he suddenly ceased, and started off full speed for a higher part of the stream. Mr. Davy was able to keep him in view, and he did not stop till he came to a spot where a plank connected the banks, on which he crossed dry-footed, and soon joined his companions.
Dogs have sometimes strange fancies with respect to moving from one place to another. A Fellow of a College at Cambridge had a dog, which sometimes took it into his head to visit his master's usual places of resort in London. He would then return to his home in Suffolk, and then go to Cambridge, remaining at each place as long as he felt disposed to do so, and going and returning with the most perfect indifference and complacency.
The extraordinary sense of a dog was shown in the following instance. A gentleman, residing near Pontypool, had his horse brought to his house by a servant. While the man went to the door, the horse ran away and made his escape to a neighbouring mountain. A dog belonging to the house saw this, and of his own accord followed the horse, got hold of the bridle and brought him back to the door.
I have been informed of two instances of dogs having slipped their collars and put their heads into them again of their own accord, after having committed depredations in the night, and I have elsewhere mentioned the fact of a dog, now in my possession, who undid the collar of another dog chained to a kennel near him. These are curious instances of sense and sagacity.
Mr. Bell, in his "History of British Quadrupeds," gives us the following fact of a dog belonging to a friend of his. This gentleman dropped a louis d'or one morning, when he was on the point of leaving his house. On returning late at night, he was told by his servant that the dog had fallen sick, and refused to eat, and, what appeared very strange, she would not suffer him to take her food away from before her, but had been lying with her nose close to the vessel, without attempting to touch it. On Mr. Bell's friend entering the room, the dog instantly jumped upon him, laid the money at his feet, and began to devour her victuals with great voracity.
It is a curious fact that dogs can count time. I had, when a boy, a favourite terrier, which always went with me to church. My mother, thinking that he attracted too much of my attention, ordered the servant to fasten him up every Sunday morning. He did so once or twice, but never afterwards. Trim concealed himself every Sunday morning, and either met me as I entered the church, or I found him under my seat in the pew. Mr. Southey, in his "Omniana," informs us that he knew of a dog, which was brought up by a Catholic and afterwards sold to a Protestant, but still he refused to eat anything on a Friday.
Dogs have been known to die from excess of joy at seeing their masters after a long absence. An English officer had a large dog, which he left with his family in England, while he accompanied an expedition to America during the war of the Colonies. Throughout his absence, the animal appeared very much dejected. When the officer returned home, the dog, who happened to be lying at the door of an apartment into which his master was about to enter, immediately recognised him, leapt upon his neck, licked his face, and in a few minutes fell dead at his feet. A favourite spaniel of a lady recently died on seeing his beloved mistress after a long absence.
