Dog training is the application of behavior analysis which uses the environmental events of antecedents and consequences to modify the dog behavior, either for it to assist in specific activities or undertake particular tasks, or for it to participate effectively in contemporary domestic life. While training dogs for specific roles dates back to Roman times at least, the training of dogs to be compatible household pets developed with suburbanization in the 1950s.
While your puppy is confined to the bathroom or his pen, he is developing a habit of eliminating on paper because no matter where he goes, it will be on paper. As time goes on, he will start to show a preferred place to do his business. When this place is well established and the rest of the papers remain clean all day, then gradually reduce the area that is papered. Start removing the paper that is furthest away from his chosen location. Eventually you will only need to leave a few sheets down in that place only. If he ever misses the paper, then you've reduced the area too soon. Go back to papering a larger area.
Once he seemingly has this idea down, move the string of bells to the left or the right of your dog and see if he moves to go and hit them with his nose; if he does click and treat! Next try moving the bells above his head and then closer to the floor. If he is chasing them with his nose in an attempt to ring them, then he understands what you want!

The 1980 television series Training Dogs the Woodhouse Way made Barbara Woodhouse a household name in the UK, and the first international celebrity dog trainer. Known for her "no bad dogs" philosophy, Woodhouse was highly critical of "bad owners", particularly those she saw as "overly sentimental". She described the "psychoanalyzing of dogs" as "a lot of rubbish". Her no-nonsense style made her a pop-culture icon, with her emphatic "sit" and catch cry of "walkies" becoming part of the popular vernacular.
Unless you plan to keep your dog outdoors--and few of us do because it's not recommended--you'll need to teach your dog where to eliminate. Therefore, house training (also called housebreaking or potty training) is one of the first things you need to work on with your dog. Crate training can be a very helpful part of the training process. This includes house training as well as many other areas of training:
