dog dream research

Signs Your Dog Is Dreaming. On the flipside, large dogs have longer dreams and may only dream once an hour. And while a dog can't tell us if or what he dreamed, the similarities lead researchers to believe that dogs do dream. There is also evidence that they dream about common dog activities.

Dog sleep is similar to human sleep in other ways. Dogs dream like humans and about similar things. Get this — research shows that a small dog, like my toy Poodle and Chihuahua, may dream once every ten minutes.

And for large dogs and small dogs, their dream episodes are slightly different.

#funfact. Smaller dogs have more frequent but shorter dream periods, Cohen said, while large dogs have less frequent but longer dreams.

Lynn Buzhardt DVM notes that research by psychology professor Stanley Coren indicates that the length and frequency of dreams may be linked to the dog’s size. Similar dream activity has been seen in dogs. For example, a Toy Poodle might display the signs of dreaming up to once every ten minutes, whereas a dog the size of a Golden Retriever may only dream once every 90 minutes. His research methods may lack sophistication, but Aristotle may not have been too far off the mark.
While we may never be able to confirm directly with a dog if they do indeed dream, comparative research indicates that during REM sleep, a dog's mind is processing and dreaming.
