When one or two puppies only are to be reared, they may be readily brought up at home, excepting in towns or other confined situations, where due liberty and a proper amount of sun and air can not be obtained. But where a larger number are to be reared, as in the case of hounds, greyhounds, pointers, and setters, etc., there is a difficulty attending upon numbers, as a dozen or two of puppies about the house are not conducive to the neatness and beauty of the garden; besides which, the collection together in masses of young dogs is prejudicial to their health. To avoid this evil, therefore, it is customary to send puppies out at three or four months of age to be kept by cottagers, butchers, small farmers, etc., at a weekly sum for each, which is called "walking" them. Young greyhounds may be reared in a large enclosure, which should be not less than thirty or forty feet long, with a lodging-house at one end; but hounds do not take exercise enough in a confined space, and should invariably be sent out.
It is only, therefore, in reference to the rearing of greyhounds that the two plans can be compared, or perhaps also with pointers and setters, if they are taken out to exercise after they are four or five months old.
The two plans' have been extensively tried with the longtails, and in my own opinion the preference should be given to the home rearing if properly carried out, because it has all the advantages of the "walk" without those disadvantages attending upon it, in the shape of bad habits acquired in chasing poultry, rabbits, and often hares, during which the puppy learns to run cunning. One of the first symptoms of this vice is the waiting to cut off a corner, which is soon learned if there is,the necessity for it, and even in mutual play the puppy will often develop it. Hence I have seen a "walked" greyhound, with his very first hare, show as much waiting as any old worn-out runner, evidently acquired in his farm yard education, or possibly from having been tempted after a hare or two by the sheep-dog belonging to the farm. Moreover, the home-reared puppy, being confined in a limited space during the greater part of his time, is inclined to gallop when first let out, and takes in this way more exercise than those brought up on the other plan; so that, after considering both methods, I have come to the conclusion that the home rearing is preferable on the whole, though there is no doubt that good dogs may be reared in either way.
The best plan is to fence off a long slip of grass; or, if a small walled enclosure can be procured, fence off about a yard or two all round, by which last plan an excellent gallop is secured, without the possibility of cutting corners, and with a very slight loss of ground. An admirable plan is to build four large sleeping rooms in a square block, and then all round this let there be a run two yards wide, which may be separated into four divisions, or thrown into one at will. If the latter, the puppies will exercise themselves well round and round the building, which is a practice they are very fond of; and, even if two or more lots are wanted to occupy the compartments, the whole can be thrown open to each lot in turn. When this plan is adopted, the run should be paved, so that the expense is much greater than in the other mode, in which the natural soil is allowable, because the puppies are not kept on it long enough to stain it
