Charles and Lizzie Peterson are visiting their cousins in the country when they find an abandoned border collie puppy, and because he loves to run and chase, they know that finding the right forever home for the puppy they name Flash will be a challenge.

Kyle's friend Drew has adopted a dog from the shelter, but the boys need to teach it manners and obedience or Drew's parents are going to send it back.

Charles and Lizzie Peterson love puppies. Their family fosters these young dogs, giving them love and proper care until they can find the perfect forever home. Charles can't stand how Lizzie acts like a know-it-all about dogs. Lizzie is older and thinks Charles should listen to what she says. So when twin Chihuahua puppies need help, it becomes a competition.
