This is a great earlier chapter book graphic novel.  A little girl follows a dog as it goes shopping one day.  And then when they go to the library, everyone thinks the dog belongs to her, so she gives it the name Pawcasso.  She pulls this off for the entire summer, but eventually the girl and the town have to find out who the real owner of Pawcasso is, and why they need to be on a leash.  This book was fun.  The illustrations are bright and colorful, and sure to interest kids in early elementary.
