In the 100th episode, Graeme Hall meets a labrador who keeps pillaging picnics and raiding bins in an attempt to steal other people's food. For owner Katie, every walk is a stress as she never knows what this artful dodger will take next. The trainer attempts to help quantity surveyor Gordon, whose border collie is holding him hostage. At the puppy school, it is time for another lesson - lead training.
Graeme Hall meets a 15-stone Leonberger, who refuses to move whenever it's time to see the vet or the groomers, and when he's confronted with stairs, he freezes. Due to his massive size, his owners struggle to move him. The trainer also visits a three generational household, where for the past two years, Jack Russell Archie has made life unbearable.
