Dogs Behaving (Very) Badly (2019)

Season 7: Episode 3

Graeme meets a glasses-obsessed terrier, who keeps making a spectacle of himself. Whenever owner Yanny wants to enjoy a bit of television, he snatches her specs and tries his best to smash them. The trainer also helps German shepherd Harley, who holds on to his tail at any given opportunity - a habit that has left his owners worried about his physical and mental health.
