Three Labrador Retriever puppies have come to visit Miss Lizardo's classroom. One is black. One is yellow. One is chocolate. The children have many questions to ask their owner. Their owner has many answers to give them. To their surprise, it turns out that the three puppies have the same mother and the same father. How can that be? The reason leads to lots of discussion. And by the time Mr. Porter leaves with Lou, Blue and Sue, the class has learned that these three puppies have something very important to teach people.
