Thelma's puppy, Tucker, is lively -- to say the least. He hasn't even had breakfast yet and already he's zooming and zigging and zagging, wagging his tail and slipping on the floor, knocking over a vase and a lamp along with the clock, the radio, and a glass of water on Thelma's parents' nightstand. His robust enthusiasm exasperates the family, but young readers will relish the antics of this lovable canine.
