A fatal fight has rocked Buckingham Palace with reports that Princess Anne's controversial bull terrier Dotty mauled to death one of the Queen's corgis.

The Queen was said to be "absolutely devastated" over the loss of her dog Pharos, which was bitten so badly it had to be put down, Britain's Sun tabloid reported.




The attack took place at the Royal Family's Sandringham estate Monday.

Pharos suffered injuries to its hind legs, one of which was broken. Royal vets tried to treat the animal but could not save him.

The Sun reported that Princess Anne was "beside herself" over the incident.

Dotty has a troubled and violent past. She made headlines last April when she bit two children, aged seven and 12, as they walked in Windsor Great Park near Windsor Castle.

Princess Anne was fined $1,165 Cdn, the first time in the modern age that a senior member of the Royal Family had been convicted of a criminal offence.

A judge spared Dotty's life after a canine psychologist described the bull terrier as "an utterly placid, playful dog."

But the judge warned that Dotty would be destroyed if she reoffended. The judge ordered she be retrained and kept on a leash in public places for the rest of her life.
