Delaney has always wanted a dog of her own, and she’s proving it to her parents by volunteering at the local animal shelter. When the shelter enlists the Sleepover Girls to help with the annual puppy fashion show fundraiser, the sleepover girls couldn't be more excited (especially Delaney!). Delaney’s parents even allow her to babysit one of the dogs overnight during the weekly sleepover. But when the dog gets lost, Delaney doesn't know what to do. Thankfully the Sleepover Girls are ready to save the puppy and Delaney's doggy dreams before the big fashion show.
