Chapter 4

Although there is some evidence that the sense of number attains a measure of development in dogs, the ability to form mathematical conceptions of any kind appears to be very weak in this species. The fact that shepherd-dogs, in a way, keep an account of considerable flocks so that they will know when one is gone astray, can readily be explained on the supposition that they know their charges individually and not in sum. The absence of arithmetical capacity is, however, less important than the lack of mechanical sense, for the reason that such incapacity is also common in the lowest races of men. Although dogs, as before noted, quickly and clearly acquire a notion of property rights in all which pertains to their owner's holdings, they appear never to extend their sense of their own personal possessions beyond the original limit to which they had attained when the species was domesticated. The creature feels a sense of personal property in his food and in his sleeping-place, but appears not to extend his conception of individual rights beyond these primitively established limits.

All our well-bred household dogs quickly learn certain bodily habits which are necessary to make them acceptable members of a household. These habits are not well affirmed by inherited instinct, but the ease with which the instruction is acquired shows that they have become prone to submit to such regulations. Culture on this line rests upon a primal instinct, originating we know not how, which leads a number of wild animals to conceal their excrement. On the other hand, these creatures exhibit no sense of modesty, though that, in a more or less complete measure, is characteristic of all human tribes whatsoever.

As regards the memory, dogs appear to have a considerably greater measure of capacity than is observable in any other group of domesticated animals. There is no question that they can recall their associations with people from whom they have been separated for a year or more. Some trustworthy anecdotes appear to establish the fact that the recollections may endure for two or three years. I have observed an instance in which the memory seems perfectly clear after an interval of eighteen months, and this concerned a person who had been with the dog for a period of not more than four days. It is interesting to note the behavior of a dog when he has failed to recognize a person whom he has known well, but from whom he has been long separated. I have a shepherd-dog that has known me well, but the friendship is often interrupted by partings of some months' duration. When, after one of these absences, I appear to him in the distance, he comes furiously towards me, quite possessed by his enmity. At a certain point in his charge a doubt begins to beset him; he moderates his pace; his roaring bark passes into a whine; and as the full measure of his blunder is borne in upon him by my voice, he becomes the picture of shame. In his perplexity, he always finds relief in endeavoring with his paw to scrape a supposititious fly from the side of his nose. He then deals with what I suppose to be an equally imaginary flea; after he has thus gained a few seconds for readjustment, he welcomes me joyously. All this is so thoroughly human-like, that even the naturalist, the professional doubter, is forced to believe that the dog's mind works substantially as his own, and that the feelings connected with the action are essentially the same.

While in the case of the elephant and the pig, and in a less measure in several other of the lower animals, we have indices of as high or even higher intelligence than the dog, no other brute shows anything like the same measure of what we may term human quality. So far as the field of the emotions is concerned, we are driven to believe that it has been bred into the kind by the ages of intimate associations, supported by the selective process which has led people to preserve the individual of the species with which they found themselves the most in sympathy. I repeat the suggestion, and shall repeat it yet again, for the reason that just here--how effectively the reader's imagination will suggest--we find a basis for the hope that, with time and care, man may bring his subjects of the lower realm into a more intimate, affectionate, and helpful relation than is dreamed of by those who look upon them as mere brutes.

The most curious limitation which we find in dogs is as to the measure of expression to which they have attained. No one who has well considered the facts can doubt that our civilized varieties of this species have something like a hundred times as much which deserves utterance as their savage forefathers possessed. Yet the capacity for giving note to these thoughts or emotions has not gained anything like the proportion to the needs. It seems, however, that some gain in this direction has been made, and that much may be won hereafter in the way of further advance. Never having known the species whence our dogs came in its wild state, we are uncertain as to its modes of expression; but, observing the varieties of dogs which are kept by savages, it seems probable that the primitive canines used their voice only in howling or yelping; that is, as a continuous sound akin to the bellowings or other cries of the various wild mammals. It is characteristic of all these primitive forms of utterance that they are, to a great extent, involuntary, and that when the outcry is begun it continues in a mechanical manner, with no trace of modulation arising from the conditions of the moment. In other words, these actions resemble, in a way, sneezing or hiccoughing in human kind; actions which are stimulated by certain states of the body, but which are not at all under the control of the will. Howling or bellowing doubtless represents, in a measure, a state of mind as well as of body, but the action is of a general and uncontrolled kind.

The effect of advancing culture upon a dog has been gradually to decrease this ancient undifferentiated mode of expression afforded by howling and yelping, and to replace it by the much more speech-like bark. There is some doubt whether the dogs possessed by savages have the power of uttering the sharp, specialized note which is so characteristic of the civilized forms of their species. It is clear, however, that if they have the capacity of thus expressing themselves, they use it but rarely. On the other hand, our high-bred dogs have, to a great extent, lost the habit of expressing themselves in the ancient way. Many of our breeds appear to have become incapable of ululating. There is no doubt but this change in the mode of expression greatly increases the capacity of our dogs to set forth their states of mind. If we watch a high-bred dog, one with a wide range of sensibilities, which we may find in breeds which have long been closely associated with man, we may readily note five or six varieties of sound in the bark, each of which is clearly related to a certain state of mind. The bark of welcome, of fear, of rage, of doubt, and of pure fun, are almost always perfectly distinct to the educated ear, and this although the observer may not be acquainted with the creature; if he knows him well, he may be able to distinguish various other intonations--those which express impatience and even an element of sorrow. This last note verges toward the howl.

It does not seem to me that we should regard barking as a new and useful invention; there are, indeed, few such in the organic world. The sound appears to me to have been derived from the primitive habit of howling. If we hearken to this utterance we perceive that it is not an unbroken sound, but is somewhat intermittent. At either end of the prolonged sound we can often notice that it is divided into rather distinct yelps more or less completely separated from the other notes. The cries of a dog when beaten often exhibit the same peculiarity; so, too, the puppy, before he has attained skill in barking, will often prolong each utterance in a way which makes its relation to the ancient mode of expression tolerably clear. At the risk of being deemed fanciful, I venture to suggest that the bark is in effect a division of the howl into clearly separated notes, the change having come about as a similar alteration is effected in our own speech, by the increase in the intelligence which the creature is called upon to express. I conceive that while the primitive and massive emotions found satisfying utterance in the long-drawn notes, the more divided state of mind of the humanized successor has led to a change in its utterances. Although these modifications of speech, if such we may term them, have probably been developed on the basis of the dog's human relations, there is, it seems to me, good reason to believe that the diversities in note have come to have a distinct conventional value between the individuals of all the different breeds. Any one who closely observes these animals must have noticed the fact that the degree of attention they give to the utterances of their kindred varies in a way which indicates that they have great varieties of denotations. Some of the shades of the meaning which a dog's bark has to others of his species probably escape our less fine ears.

The creation of something like a language among our civilized dogs has naturally been accompanied by the development of an understanding of human speech. Although we cannot attach much importance to the mass of anecdote on this point, there is enough which is well attested--sufficient, indeed, which has come within the limits of my own observation--to make it clear that dogs, even without deliberate teaching, frequently acquire a tolerably clear understanding of a number of words and even of short phrases. They will catch these not only when given in distinct command, but when uttered in an ordinary tone, without any sign that they relate to their affairs. It is true that these understood words generally relate to some action which the dog is accustomed to perform, yet there are instances so well attested that they deserve credit, which seem to show that the creatures can get some sense of the drift of conversation even when it is carried on by persons with whom they are not familiar and does not clearly relate to their own affairs.

It should be observed that within the narrow limits of this essay little or no effort has been made to interpret the state of mind of dogs from the vast but rather untrustworthy mass of anecdote with which our books are filled. So large a part of this evidence is contaminated by prepossessions, and a yet larger part is so unverified in any scientific sense, that for purposes of sound inquiry it is worthless. It therefore seems best to limit ourselves, as has been done in this paper, to those general actions of the creatures which are matters of common knowledge and safely beyond question. From these indices we are able to determine a basis for some important conclusions. These are in effect as follows, viz.: Our domestic dog is derived from a species, one or more, akin to the wolf, the jackal, and the fox; to a group of animals not characterized by great native intelligence, but distinguished for their ferocity and their general untamableness. There is no reason to believe that the primitive dog had any more foundation for his great attainments than his obstinately savage kindred, except that he may have had a greater disposition to form an attachment to a master. We can hardly believe that he had any share of that marvellous sympathy with man and understanding of his motives which characterize the high-bred varieties of his species. All this vast transformation, which from a psychological point of view has carried the dog relatively as far up above his origin as civilization has lifted man above his lowest estate, has been due to human intercourse and the long and effective concomitant selection of good from bad. It is hardly too much to say that a large part of our human nature has been transferred into the descendants of this ancient wild beast. The sense of property, a great part of human affections, many of the attributes which constitute the gentleman, have been passed over to him.

In considering the effects arising from the intercourse of man with the dog, we should not overlook the development of human sympathy which has come about through this relation. The fact that the dog has been made by far the most sympathetic of the lower animals, is due to the affection which men for thousands of years have given to him. In his intercourse with this creature, man first learned to develop his altruistic motives beyond the limits of his own kind. With this extension of his affection must have begun the growth of that large motive, which is the most distinguishing feature of our modern life, which leads us to go forth in a loving manner to the living beings about us, not only to our flocks and herds but to the life of the unsubjugated realm as well. Thus, in a way, we may look upon the dog as affording the first steps on the path of culture which was to lift man from his primitive selfishness to the altruistic state to which he has attained.

Great as has been the work of man upon the dog--it deserves, indeed, to be ranked high among all the accomplishments of his culture--there is reason to believe that if he but go forward with understanding in the ways which have hitherto led him blindly to his success, the final result may be very much more perfect than that which has been attained. It is on this account that I feel it fit to make a strong protest against the system our breeders pursue. Except in the case of dogs used in sport and for herding sheep, the sole effort appears to be to create breeds which shall exhibit peculiarities of form which are mere extravagances, and move the real lover of this noble animal to indignation. In these preposterous and unseemly tasks no care is taken to continue the mental development on lines which have been established by long use. Still less is there any effort to essay the development of the intelligence in ways which are clearly open to us, and which afford possibilities of lifting this species to a yet nobler companionship with our own kind.

It seems worth while for our associations of dog fanciers to undertake to develop varieties of dogs solely with reference to the intellectual qualities of the animal. I venture to suggest that those who seek this end should select some of the primitive types of form, such as are found among the undifferentiated mass of the species, those which are improperly termed mongrels, and this for the reason that among these unselected creatures the intelligence is quicker and more varied than it is in the highly developed varieties. Under skilful trainers the successive generations bred in the experimental station should be subjected to tests which will indicate the measure of intellectual ability. The results already attained by the unconscious selection which man has applied serve to indicate that at the end of a century, and perhaps in much less time, we might develop an animal which in various ways would come to a closer intellectual relation with man than any other lower species has attained.

Cats deserve some mention for the reason, that, while they are the least essential, and on the whole the least interesting, of domesticated animals, they have had a certain place in civilization. They afford, moreover, a capital foil by which to set off the virtues of the dog. Nowhere else, indeed, among the creatures which are intimately associated with men, do we find two related forms which afford, along with a certain likeness, such great diversities of quality.

We know nothing as to the time when the cat first found its way to the associations of man. Presumably this period was much later than the advent of the dog into the human family. The presumption rests upon the fact that while the dog does not demand fixed residence as a condition of its fealty, but is at home wherever his master is, the cat is the creature of the domicile, caring more indeed for its dwelling-place than it ever does for the inmates thereof. In a word, the creature must have come to us after our forefathers gave up the nomadic life. Nevertheless, the association is very ancient; it has endured in Egypt at least for a term of several thousand years.

Among the curious features connected with the association of the cat with man, we may note that it is the only animal which has been tolerated, esteemed, and at times worshipped, without having a single distinctly valuable quality. It is, in a small way, serviceable in keeping down the excessive development of small rodents, which from the beginning have been the self-invited guests of man. As it is in a certain indifferent way sympathetic, and by its caresses appears to indicate affection, it has awakened a measure of sympathy which it hardly deserves. I have been unable to find any authentic instances which go to show the existence in cats of any real love for their masters.

In the matter of intelligence cats appear to rank almost as high as dogs. They are even quicker than their canine relatives in discerning the nature of man's artful contrivances; they readily acquire the habit of opening doors which are closed by means of a latch, even where it is necessary to combine the strong pull on the handle with the push that completes the operation. Feats of this sort are rarely if ever performed by dogs.

The most peculiar quality in the mind of cats is the intense way in which they cling to a well-known locality. Their memory of places, and affection for them, if we may so term it, is evidently far greater than that which they feel for people. Some years ago I had an interesting exhibition of this singular humor. A well-grown and thoroughly domesticated cat, one that seemed more than usually attached to people, was brought from my house in town to a place on the shore. When released, the creature seemed for some days to be nearly insane. It did not recognize any of its friends, it betook itself to the fields, and was with difficulty captured at the end of a week of roaming, during which it appeared to have had no food. Confined within one room, it gradually recovered its powers of mind, and began to take account of its friends. In the course of a month it seemed to be reconciled to its surroundings. Nine months after its first sojourn in the wilderness it was again brought from the town to the same place. On the second visit the creature was somewhat uneasy, but this passed away in a day or two. On a third visit, after a like interval, it seemed at once and entirely at home. Nevertheless, its habits while in the country differ very much from those it has in town. In its original domicile it insists on being about the table at meal-times. While in the country it does not care to be present; in fact, it appears to avoid associations with the household. It seems to me that this cat, after the manner of some men whose brains are diseased, now lives in two distinct states of consciousness, each relating to one of its places of abode.

The differences as regards affection for localities which is shown by cats and dogs are perhaps to be accounted for by an original and essential variation in the habits of life in their wild ancestors. Judging by the kindred of the species which are known to us in their wild state, we may fairly suppose that the dogs were of old accustomed to range over a wide field, having no fixed place of abode; the pack ranging, if the occasion served, for hundreds of miles in any direction. On the other hand, with the cats, it is characteristic of the species that they have lairs to which they resort, and a definite hunting ground in which they seek their food. They are, in a word, animals of very determined routine. As there has been no effort by breeding to change this feature, it has remained in all its old ingrained intensity.

As a consequence of the affection which cats have for particular places, they often return to the wilderness when by chance the homes in which they have been reared are abandoned. Thus in New England, in those sections of the district where many farmsteads have of late years been deserted, the cats have remained about their ancient haunts and have become entirely wild. In this State they are bred in such numbers that their presence is now a serious menace to the birds and other weaker creatures of the country. The behavior of these feralized animals differs somewhat from that of creatures which have never been tamed. They have not the same immediate fear of a man, but the least effort to approach them leads to their hasty flight.

While considering the inelastic quality which is exhibited by cats as compared with the dog, the naturalist notes with interest the fact that the former creature belongs to a family which has never been accustomed to any social life beyond the limits of the family. Moreover, all the cats have the habit of hunting in a solitary way, each for itself, in the achievement and in the result. It is otherwise with dogs. They belong to a group which hunts in packs. For ages they have been used to a communal life. Their minds have thus become accustomed to social intercourse; they are used to having their excitements of the chase in comradeship, and generally they are accustomed to the rough-and-tumble fraternity which we behold in a pack of wolves. It was long ago remarked that the really social animals are those which afford the only good material for subjugation. The difference between the cat and dog seems, in a way, to warrant this statement.

Although it is likely that many efforts have been made to domesticate the other larger felines, no distinct success has attended these experiments. A large Asiatic cat known as the chetah is somewhat used in hunting for sport, but the species has never been adopted in any definite way. In fact, with all the larger cats, including the lion, which is structurally a little apart from the other members of the group, the size and furious nature of the animal have made it impossible to begin the process of selection which has been the means whereby the wilderness motive has been replaced by that of the household in the case of all other domesticated beasts.
