Most animals that are born in a nest have an instinctive desire to move away from the nest to relieve themselves. They will do so without being taught as soon as they are able. Dogs are no exception, and at the age of about three weeks, they will begin to leave the sleeping area to urinate. We just have to teach them that houses are our nests, and that they have to move outside when they want to relieve themselves. Take your puppy outside to the same spot in your yard or garden at the following times:

1. Shortly after each feeding, playing, exercise, and any excitement.
2. Immediately upon waking
3. First thing in the morning
4. Last thing at night
5. Once every hour

It is important to stay outside with him. Be patient and wait. As soon as he begins, say a chosen phrase to him such as "Be clean!".When he has finished,praise enthusiastically and play a game with him. Keep the area clean by picking up any mess and flushing it down the toilet.   More detail...
