Muffin, the little black Pug, is back. Muffin's parents must send Muffin to school because she has been "messing up." It is time that she learns to behave. Muffin does not want to go but that is before she meets Winston, Puddin, Doc, and Maddie. Most importantly, she meets Rusty who helps all the puppies with their lessons. The puppies look different, but they become best friends and learn from each other. Under the guidance of Rusty and their teacher Ariel, the puppies master their commands and graduate from Puppy Class. Children will laugh aloud at Muffin's antics and the colorful illustrations bring the story to life. Not only children will love reading the book, but parents and grandparents will also be entertained.
