Episode 4 (S01E04)

Trainer Graeme Hall tackles various dog behavior issues, starting with a family in East Sussex who are having difficulties with their rescue puppy, Diego, a mix of Rottweiler and Rhodesian ridgeback. Next, in Cambridgeshire, he encounters Doug the cocker spaniel, whose constant stealing is wreaking havoc on Julie and Mark's hopes for a tranquil retirement. Graeme's journey concludes in Derby, where he meets two miniature schnauzers, famously referred to as the Krays by the locals.
