Trainer Graeme Hall meets model aircraft enthusiast Ray, who was looking forward to enjoying his retirement alongside Henry, his latest doggie addition. But this Welsh terrier loves nothing more than harassing Ray whenever he wants to do anything around the house. Graeme also comes to the aid of Adele, whose Pomeranian Teddy has a nasty biting habit that has forced her to wear heavy-duty gloves whenever they go for a walk.

Graeme meets a German Shepherd called Jake that has been driving his owner crazy with his constant outbursts on walks and barking through the night, meaning owner Danielle cannot remember the last time she had a proper night's sleep. Later, he meets a little terrier that has been tearing a couple apart with his jealous behaviour, and a dog that is terrified of household items.
