A humorous tale about a hard-barking pup who realizes his job is to expose prowlers – but can’t figure out how to identify them. He accosts the postman, the milkman, innocent visitors, family members sneaking home late at night and generally makes, an unholy nuisance of himself. When a real prowler does come, Puccini decides, he’s much too nice to mean any harm. The family decides he’s no watchdog, but Puccini at least makes a noise like one, “which is enough to fool all honest people.”
