I do not believe in chaining dogs up in a yard, but if you want him chained at night don't make it too short - and he must have freedom during the day. To keep a dog chained constantly day and night is cruel and inhuman, and will make any dog cross. Dogs are not born cross - you never saw a cross puppy - and when you see a cross dog some human being - man, woman or some good-for-nothing boy - is to blame for it, not the dog. There would be no cross dogs if people were not the cause of it by their ill treatment of the dog any more than there would be a balky horse only for men - fools and brutes - who make balky horses.
If you must chain the dog up during the day, then give him his liberty at night. It is not necessary to chain him up if you have a yard with a fence high enough and gate securely fastened. Many a bad boy will delight to tease your dog simply because he sees he is chained up - for the boy would be afraid to if the dog was loose - and this teasing makes a cross dog. I don't blame the dog, but I do the boy.
If you have no yard fenced in and a large dog and must keep it on chain part of the time, allow at least 20 feet of chain. Fancy the misery of a man full of life and energy trying to take exercise by pulling and ■training against a chain three or four feet long. Yet this is the length which some otherwise humane people seem to think a just allowance for the yard dog. The chain should be fastened to a stake about 18 feet from the kennel.
Should there be no enclosure for your dog to romp in and must therefore be tied up to prevent loafing, straying, or getting coaxed away and stolen, then proceed thus in securing and still enable him to move about tolerably freely: Get a strong wire, ten to forty feet long, slip a ring on it, fasten wire at each end to stout stake, drive the stakes at full stretch of wire into ground to below the surface. Hook the dog's chain to ring running freely on the wire, and your dog can run up and down this course at will. By attaching such a wire to the side of a long wall or house, a runway can be provided in similar manner. The kennel can be placed a few feet beyond the end of long wire so that the dog can get to and into it without needing to be changed.
