Lauren the Puppy Fairy is the book no. 32 in The Pet Keeper Fairies series of books. In this case, the missing pet is a puppy. Rachel and Kirsty a Spring Show (sort of a county-fair type of thing) and there is a pet shelter display. All but one of the puppies is quickly adopted.
Rachel and Kirsty meet Lauren, the Puppy Fairy, and they search for her missing pet, once again having to deal with the goblins (who are so inefficient and stupid that it’s no wonder Jack Frost is always in a bad mood.)
Kristy and Rachel are at the spring fair and there is an animal shelter booth. There are four little puppies and when the fair is over they guy who owns the pet shop lets Rachel and Kristy take the last dog for a walk. While they are walking him they see another puppy but no one was walking him and he didn’t have an address or anything on his collar, just a name tag. His name was Sunny. He is Lauren’s magical puppy. The puppy plays with Sunny for awhile then they keep walking. When they’re walking they see a girl and she really liked the dog and she bought it from the animal shelter so the last puppy finally had a home. At the end Lauren brings Sunny back to Fairy Land.
