Purchase one of several breeds available at the beginning of the game, then start spending time with your pup. Throw flying discs and balls to improve the pup's agility, bathe it when it gets dirty, and repeat voice commands to train the dog to do tricks. If you train it well enough, you'll excel in dog shows and agility contests, which will earn you money to buy other supplies and puppy breeds. When you earn enough cash, you can buy even more puppies to live with yours.
