"Nintendogs" features a variety of contests, which are the player's main method of earning money and trainer points. There are three contests: Disc Competition, Agility Trial, and Obedience Trial. In each of them, there are 5 classes: "Beginner", "Open", "Expert", "Master", and "Championship". Each contest is commented on by two men, named Ted Rumsworth and Archie Hubbs. (It was said that Archie sometimes eats dog treats. ) If the player's dog places 3rd or higher in its class, the dog will proceed to the next class, where the contest increases in difficulty level. Prize money earned differs depending on which contest has been entered, what place is finished, and the class the dog is in. If the player does not place at least 3rd, they will be dropped to the previous difficulty level, unless they were in the Beginner class, at which point they will remain there. Dogs that are especially dirty or hungry are not able to participate in contests.
