British performance artist Mark McGowan ate a few bites of a corgi dog live on the radio to protest Prince Philip's hunting of a fox. Yoko Ono had a bite as well. The corgi is apparently the Queen's favorite breed. According to McGowan, it tastes lousy. From Reuters:
The dog died of natural causes at a corgi breeder and was prepared and cooked by others for McGowan…
McGowan is well known for his outlandish performance stunts. He ate a swan in another protest against the queen. Swans are protected by the monarchy.
UPDATE: Yoko didn't eat the dog. Reuters issued a correction. Link
