Beryl and her fox-terrier, Tibby, live next door to Jack and his dog, Rowdy. Tibby is mischievous, and although Beryl at times feels like smacking her, she realises that her pup is merely being playful. Jack spends a lot of time training Rowdy, who carries a basketful of groceries home from the shops and collects the daily paper from the newsagent's. When Tibby is involved in an accident, Rowdy stays by her side until help arrives.
