What would the world be like if dogs turned into super heroes? On a regular day at Fernfield Farms, five Golden Retriever puppies named Budderball, Rosebud, B-Dawg, Buddha and Mudbud discover some intriguing coloured rings that, when worn as collars, grant the wearer an extraordinary super power. Mudbud, for example, is given the power of invisibility, while B-Dawg becomes super stretchy and Rosebud super speedy. Like any young thing gifted with enormous power, they need a mentor and when comic book hero Captain Canine comes to Earth to explain about the Power Rings of Inspiron, they find themselves banding together to become the most powerful puppy litter ever - which is just as well, because an evil shape-shifter is on his way to destroy the planet once and for all.
The film is almost half an hour longer than 'The Force Awakens'.
The actress will no doubt be returning for the long-running FX series.
The film is expected to continue without Mendes' involvement.
