Do dogs have dreams?
Good night, sleep tight. Fido has sweet dreams too.
Asked by: Hannah May Lathan, Oxford
Yes. In 2001, researchers at MIT monitored brain activity in rats as they solved a maze. They found that the animals showed the same brain activity patterns during sleep. The match was so close that the researchers could tell which part of the maze the rat was dreaming about. Cats and mice show similar results, so it is likely that visual dreams are common to all mammals, including dogs.
