An adventure series based around helping animals big and small, fully endorsed by the RSPCA. Cassie Bannerman is a nine-year-old girl who love animals, especially her dog Ripper, who is always by her side. She lives close to the local RSPCA shelter, and she knows everyone and everything that's going on in her local neighbourhood. When Ben Stoppard moves into Abbotts Hill with his English sheepdog, Florence, Cassie is determined to befriend them both. The four of them take part in the RSPCA fundraiser, The Million Paws Walk, and team up together to help round up a naughty runaway pup.
