Terry and June find a budgerigar outside their bedroom window, and after returning it to its owner via the Police, they think about getting pets. Before Terry can decide, June agrees to 'dog sit' Boobalinka, a Yorkshire Terrier, for a friend, as well as many other animals, including budgerigars, rabbits, a ferret, Guinea pigs, gerbils, mice, goldfish, terrapins, ants and a Grass snake; much to Terry's annoyance. Soon, Terry lets the dog out, not realising it will run away. He then searches the streets for it, and accidentally goes into the wrong house thinking she is inside. June persuades the house's owners (Peter Stenson and Sue Lynne) that it was a genuine mistake. Hours after running away, the dog returns on its own and eats Terry's steak.
