Play games with your pet to keep good behavior interesting and fun, and to practice what your dog already knows.

For example, play "pet pingpong" in a closed hallway, with one person at each end, when your dog is hungry. Start the game with each person taking turns calling the dog for a treat. As the game progresses, ask your dog to "sit," "shake" or "lie down" for the treat.

As you raise the bar, increase your praise. Keep your dog guessing. Give a treat quickly for coming one time, and then randomly ask for two or three behaviors before the treat at other times. Keep the game brief and end on a high note.
