Episode 4

Matt Gough co-ordinates a mammoth operation involving the police, the fire service and the RSPCA to remove 72 dogs from an Essex farm. In Plymouth, inspector Sarah Morris catches a Border collie that has run away from its owner and the dog is sent on a training day, while the programme also visits Ruffs - the RSPCA's alternative to Crufts that has categories including Happiest Hound and Perfectly Imperfect. There is also a catch up with Lupo, a Rottweiler cross rescued last year from a filthy caravan on a Welsh farm.
