Pawcasso / by Remy Lai.

Every Saturday, Pawcasso trots into town with a basket, a shopping list, and cash in paw to buy groceries for his family. One day, he passes by Jo's house, where she's peering out the window, bored and lonely. When Jo sets out to follow him, a group of kids from school mistake her for Pawcasso's owner and, excited to make new friends, she reluctantly hides the truth. But what starts as a Chihuahua-sized lie quickly grows into a Great Dane-sized problem when Pawcasso gets his own internet fan club. Trapped in a web of lies, will Jo risk her new friendships by telling the truth? A story about an unexpected friendship between the loneliest girl in class and the coolest canine in town.
