This is the second book in The Buddy Files series. It was a fun little chapter book about a dog, Buddy that is trying to solve two mysteries. First, he is still trying to find his first family and figure out what happened to them, making him end up at the pound. (This was the premises for the first book.) In this book, along with still trying to solve the mystery of his missing family, he is presented with a more urgent mystery. Two pugs were switched at the dog park and he is the only one (with a little help from his dog friends) who can solve this mystery and fix the situation. This is a fun series for younger grades that are quick and fairly easy to read with a little adventure and mystery.
