Loki is an XL American Bully. People look at him and think he is one mean dog. However, he is a gentle giant. Don't Be a Bully is a book to help children understand that being a bully isn't a nice thing to be and that it really can hurt other kids. This book sheds light on ways that kids bully other kids and how kids are bullied. Even though Loki is a bully, he doesn't act like one, and he doesn't want kids to be bullies either!
