Kate loves her family's three dogs, but sometimes she wishes she could do other things instead of walking them every day-especially the puppy, Spot. One day, when Kate's little brother has a dentist's appointment, Kate is expected to walk Spot on her own when she gets home from school. She decides to let the puppy out alone instead, and she forgets all about him until supper time. The whole family is upset...except for Spot himself! The puppy is busy having his own new experiences and adventures, exploring the world around him.

This delightful novel for young readers follows Kate and Spot as they explore the joys and dangers of life. They learn about the nature of responsibility, the thrill of adventure, and just how much one little dog can mean to a family.
