Chloe, a smart and adventurous girl, is just back from an imaginary secret mission with her best four-legged friend, George. Chloe had known George all her life, and he was the world's most amazing super pup. One day, the world's most amazing super pup started to slow down and ultimately had to say goodbye to Chloe.

Through a series of events, Chloe gets thrown into the paws of a small scraggly and incredibly loud ball of matted fur, named Sophie. Although apprehensive and reluctant to make a new friend, Chloe's life was about to change forever, Sophie would make sure of it.
