When May was little, she begged and pleaded for a dog. Now that she’s all grown up, she’s finally got him. Julian is a big-eared, high-spirited farm dog, whose job is to chase groundhogs out of the garden. In fact, Julian chases anything that moves, from cars to the neighbor’s horse. And he also chases May’s gentle black cat Victoria, and her kitten Ricky Rainbow, who scramble for safety whenever Julian appears. But one day Julian proves that he really is a good dog, a hero in fact, and May, Victoria, and Ricky Rainbow can really count him part of their family.
