Who has better dreams, your dog or a duck-billed platypus?

Ever seen your dog start to wag, whimper, or wiggle around during sleep? That means your dog is dreaming. Dogs are mammals, and like other taller, less furry mammals (humans) they experience REM sleep, the section of the sleep cycle where we dream.

The duck-billed platypus experiences more REM sleep than any other mammal. They also lay eggs. And have bills. Go figure.

What does your dog dream about?

Mine has a reoccurring dream of becoming a smurf...


Beat that platypus!
