One-Third Nerd by Gennifer Choldenko

4.0

5th grader Liam is one-third nerd, which is fine with him, but little sisters Dakota (all nerd, all the time), and super friendly Izzy are raising his percentage. Their dog, Cupcake, is having accidents in their apartment and their landlord says the dog has to go. The family can't afford to take the dog for an expensive procedure at the vet. Will the kids be able to figure out how to save Cupcake.
