We had 5 dogs all in all although we now have only 3. All those dogs arrived in our home when they were puppies because I don't want to accept older dogs. For their toilet training, I have learned the trick of the old newspaper. Laid out on the floor, we place the puppy on the newspaper and let it stay there until it does its thing - urinate or defecate. On the second day, the puppy would already know what to do when we place it on the newspaper. After a week or 2, we would be placing the newspaper in the front yard. That way, the puppy will do its thing on the newspaper because it is already getting to be a habit. And after a month, when the puppy ignores the newspaper, it would do its thing outside the house.
