"Boys are Dogs" by Leslie Margolis

Sixth grade Annabelle just moved into a new house with her mom and her mom's boyfriend Ted Weeble. Annabelle creates a secret nickname for Ted, Dweeble, which is very fitting with his dorky running shorts and nerdy music. New house equals a new school, and her new middle school is filled with pesky boys that take great pleasure in teasing and tormenting Annabelle. Mom and Ted surprise Annabelle with a new puppy, hoping the distraction will help her adjust. Annabelle soon discovers that boys and dogs have a lot in common, and dog training is coming in very useful for putting boys in their place! This is a funny read, Annabelle is super clever and confident.
