Guests at Clifford's birthday party learn to count from one to ten, including one giant red dog, two balloons, three presents, four dog friends, five chairs, six trees, seven candles, eight sacks of dog food, nine balls, and ten cats.

Offering Emily Elizabeth's team an unfair advantage on sports field day, Clifford the big red dog joins in the sack race and tug-of-war, but everyone decides that he is okay when he rescues a ballplayer from being hit by a car.

Clifford, a small red puppy, helps Emily Elizabeth and her parents decorate the Christmas tree, wrap presents, and enjoy Christmas day.
