When Lizzie meets a mischievous young pug named Pugsley while working at her aunt's day care center for dogs, she steps in to train Pugsley so that he can get a good owner.

Nanny Paws looks after Ally and Mae the only way she knows how--as a dog would. There's nothing she wouldn't do for her girls. She feeds them a hearty breakfast (cookies are best), picks up their toys (teddy bears fit nicely in freshly dug holes), and even walks them to school (running them there is fun too). But one Tuesday, Ally and Mae come home sick, and it's up to Nanny Paws to take care of them, in her own special way.

"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. Who will find a home first for these super-special pups?"--Back cover.
