All puppies require a dry lodging, and in the winter season it should also be a warm one. Greyhound whelps, up to their third or fourth month, are sometimes reared in an artificial temperature, either by means of a stove, or by using the heat of a stable, the temperature chosen being 60° of Fahrenheit. Beyond this age, it can never be necessary to adopt artificial heat in rearing puppies, because for public coursing they are required to be whelped after the last day of the year, and four months from that time takes us on to May, when the weather is seldom cold enough to require a stove; then during the summer months they are gradually hardened to the vicissitudes of the weather, and as they become older their growth is established, and they are no longer in danger of its being checked. It is true that some few breeders always keep their kennels at 60°; but on the whole, as we shall hereafter find, the plan is not a good one, and need not be considered here. But far beyond the warmth, dryness is essential to success. Dogs will bear almost any amount of cold if unaccompanied by damp, provided they have plenty of straw to lie in; but a damp kennel, even if warm, is sure to lead to rickets or rheumatism, if the puppies escape inflammation of some one or more of the internal organs.

Take care, therefore, to give a dry bedstead of boards, lined with the same material towards the wall (the cold of which strikes inwardly and gives cold), and raised somewhat from the floor, which will otherwise keep it damp. Puppies soon learn to lie on this, and avoid the cold stones or bricks, except in the heats of summer, when these do no harm. The stone or brick floor should be so made as to avoid absorption of the urine, ctc., which can only be effected by employing glazed tiles or bricks that are not porous, or by covering the whole with a layer of hydraulic cement, or with asphalt, which answers nearly as well. Care should be taken that there are no interstices between the boards, if the kennel is made of them; and in every way, while ventilation is provided, cold draughts must be prevented. Cleanliness must also be attended to rigidly by sweeping out the floor daily, and washing it down at short intervals, and by changing the litter once a week at the least. In the summer time, straw is not desirable, as it harbors fleas, and, if the boarded floor is not considered sufficient, a thick layer of pine sawdust will be the best material, as it is soft enough, without harboring vermin of any kind; the only objection to it being that the puppies are apt to wet it often, after which it becomes offensive.
