Summer McKinny loves dogs and she loves baking, so she starts Waggy Pup Tails, a dog walking and treat baking service. Part of her profits are going to Four Paws, the animal shelter where she adopted her dog, Crescent. When Aunt Olivia comes to stay, she brings lots of creative ideas for Summer's business. She also brings her feisty feline, Fettuccine. Crescent isn't sure what to do with a cat in the house, and Fettuccine keeps escaping. It's up to Summer to help them get along AND get ready for her very first youth entrepreneur fair. Paws crossed she can do it!
