Episode 1

A team of expert trainers, and presenter Nick Grimshaw - dog-dad of two - take on the nation's naughtiest dogs... and their humans. Eight-stone puppy Ghost, a Cane Corso mastiff, is striking terror into the heart of the neighbourhood, and his owners. While his guard dog credentials are impeccable, can he be trained to be compatible with family life? Will he even let trainers Sean and Kamal come anywhere near him? And newly-engaged Chelsea and Owen have their hands full with, and their relationship tested by, Chelsea's six chihuahuas and a cavapomchi called Mr Bollinger.
