Personally I don't think dogs should be left alone tied up, especially pups, too many bad things can happen. But if you must tether a dog, don't put it near the chickens. A lot of people seem to think that will help the dog "get used to" the chickens, but often it will actually cause the dog to become even more determined to get them.
Back tying has long been used in K-9 training to build and increase drive through frustration.
