Florence, one of Princess Anne's three pet bull terriers, has attacked a royal servant only days after savaging one of Queen Elizabeth's dogs (which subsequently had to be put to sleep), Buckingham Palace told Reuters on New Year's Eve.

Anne, 53, the queen's only daughter, seems to have little control over her animals.

The princess was the first British royal to be convicted of a criminal offense in 350 years when she pleaded guilty in November after she failed to stop another of her dogs, Dottie, from biting two children in a London park. (Anne was fined $880 and ordered to pay the same amount in damages but could also have faced six months behind bars.)

Florence's latest infraction reportedly occurred at the queen's Sandringham estate in rural Norfolk on Saturday, when the dog bit a maid on the leg. The servant was treated by a doctor, said Reuters, noting that English bull terriers are a stocky breed of dog with powerful jaws. The pit bull is an American cousin to the English bull terrier, according to some dog-breeding Web sites.

This is an unfortunate turn of events for Florence, who now has a history of aggressive behavior. On Tuesday it was announced by a royal spokesman that she – and not Anne's other dog, Dottie, who previously had been blamed – was the culprit who had brutally attacked one of Queen Elizabeth's beloved corgis, Pharos, who had to then be put to sleep last week as the royal family gathered to celebrate Christmas at Sandringham.

Already there have been calls to have Florence put to death, say British press reports, but the palace would not comment on the matter to Reuters.
