Book excerpt: Potbellied pigs are unique pets. They are quite smart, so they are easy to train. They learn tricks quickly. They love company, so they always want to hang out with you, playing games, chasing a ball, and even cuddling on your lap. Just like a dog, pigs like to go for walks. Once you convince your parents that you can care for a potbellied pig, put on your sneakers, grab a leash, and hit the sidewalk! Chances are everyone will want to stop and see your charming new pet.
