Kate and Lucie are best friends. Kate is neat and Lucie is messy. Kate wakes up early and Lucie loves to sleep in. But both girls love, love, love dogs!

Unfortunately, Kate and Lucie live in apartments where dogs are not allowed. Instead of real dogs, they have dog T-shirts, dog sheets and pajamas, and dog books. But nothing is quite the same as having a real dog.

One day, the girls discover sparkly pink dog necklaces at the thrift store and try them on. But when they admire themselves in the mirror and give each other high fives, there is a pop and a whoosh and the girls are turned into dogs! Now it seems like Kate and Lucie won't need their own pet dogs . . . because they'll be having furry adventures of their own!
