Muffy is a happy and curious Goldendoodle puppy who lives on a farm. One day she chases a silly grasshopper and gets lost. She finds herself alone and hungry, on the point of collapse, but luck is on her side and she is adopted by a wonderful family, the Gabriels, who have a very orderly and devoted pack of dogs. Muffy becomes part of her new family, and is accepted by Radar and Oliver and the gang, but she still pines for her sister, Riff, and misses the farm. One of her new friends, Wise Dog, introduces her to a very unusual Dog Catcher who has a special talent.
Muffy’s courageous journey is full of laughter and adventure as she tries to unite her two families.
