As soon as your puppy begins to walk, he should have plenty of exercise, on the ground, if possible, and out of doors; but if this cannot be given him, the box stall or a pen under an open shed will answer. Do not, however, neglect to keep the sand or soil perfectly sweet and free from filth.

When the puppy is about six weeks of age, he should have a good-sized pen out of doors, with a kennel that will keep out the rain; and, if the weather is cold, the kennel should be close and warm, with a heavy piece of old carpet nailed over the door at the top, and left hanging over the entrance, to exclude cold and wet. If you cannot give him a large pen, he should be let out for a run of an hour at least twice a day. This is imperative if you would have a healthy, vigorous animal. A dog should never be kept on chain; but if this is unavoidable, you can overcome a portion of its disadvantages by stretching a long wire - overhead, to be out of the way - between two posts or trees, and attaching the chain to a ring that will slide on the wire, thus giving him exercise and a partial relief from heart - breaking confinement.

Pure air and sunlight are of the greatest importance; in fact, they are indispensable to the health of most animals, and too much stress cannot be given to the neces-sity of rearing your puppy where he can have plenty of the former at all times, and at least two or three hours of the latter every bright day. It is true that many animals live in apparent health when surrounded by noxious odors and deprived of sunlight, but in such cases disease sooner or later generally overtakes even the most hardy and vigorous specimens.
