No Pranks on Queen’s Dogs
When we talk about practical jokes, Queen Elizabeth herself possesses a good sense of humor. She even appreciates good pranks, but only when they are centered around her. Anything that links or involves her dog is not tolerated at all. The Queen loves her dogs a lot and is always concerned about them and that is why she can never tolerate any pranks that involve her dogs.
In 1999, a footman tried playing a practical joke on her Royal corgis. He put some whiskey and gin in the dog food, expecting a stir of laughter from the Queen, but he was wrong to expect this reaction as the Queen was displeased by this and demoted the footman. So no pranks on her dog at all!
