The whelping-place, up to the third week, may be confined to a square yard or two, floored with board as already described.
After the third week, when the puppies begin to run about, access should be given them to a larger run, and an inclined plane should be arranged for them to get up and down from their boarded stage. If the weather is cold, the best place for a bitch to whelp is in a saddle-room warmed by a stove, or an empty stall, with a two-foot board placed across the bottom, opposite the stall-post, so as to prevent the puppies getting among the horses. In either case there is an amount of artificial heat, which conduces to the growth of the puppies, and allows them to be reared sufficiently strong to bear any cold afterwards with impunity. If the weather is not cold, an ordinary horse-box is the best place which can be chosen, fixing the boarded stage at a distance from the door, and either sanding or slightly littering the brick floor, according to the weather; but the latter is to be preferred, excepting in a very hot summer. In these boxes puppies take a vast amount of exercise, which they require for health, and to give that appetite without which sufficient food for growth is not taken.
