It is only a few decades since the high point of the Spring Cleaning Spaniels career, when the dogs could be found throughout the UK, Europe, and North America, leading a hand, or paw I should say, with the cleaning.
The main champion of the Spring Cleaning Spaniel breed was the the cleaning fan and obsessive Doris Bustle, legendary housekeeper to Industrialist and billionaire Dustin Mophead IV. Bustle found that it was taking way too much time to take care of the one hundred and thirty nine and a half rooms of Mophead's mansion, and so sought to revive a breed once popular with stately homes throughout Europe. Bustle was successful, and soon the Spaniels started spring up again.
The British Museum in London even employed them at one point, until the notorious ming vase incident.
Ultimately the spaniel's sheer enthusiasm for the task at hand was it's undoing, for it tended to flood the kitchen while washing up, move the dust around rather than pick it up, and generally act like a miniature version of a bull in a china shop. They can still be found, but it is advised that this good-natured, but somewhat scatty breed is perhaps best of working under direct supervision.
