The dog dream mystery is finally, FINALLY over! Thanks to a very smart human being from Harvard University, we now know what our beloved pets are dreaming about and it’s pretty freakin’ cute. Is it all about tennis balls and treats? Let’s hope so.
The woman behind the dog dreaming mystery is Dr. Deidre Barrett, who is a teacher and a Clinical and Evolutionary Psychologist at Harvard Medical School. She started the interesting study thanks to the USA Network. Their interest in animal dreams all stem from a past TV show they produced about dreams and realities. Unfortunately the show no longer exists but at least we got this study from it!

Thanks to Dr. Barrett, whose deep interest in dreams began at an early age, gave us all the answers we’ve always wanted to know. People.com asked Dr. Barrett several questions. Here’s what she said.
How are animal dreams different from human dreams?
Anything about what animals dream, or even if they dream, is speculative. The only two animals even suggested to have ever told their dreams to a human are the signing gorillas Koko and Michael. Researcher Penny Patterson reports that Koko occasionally signs about fantastic events, people and places she has not seen recently only upon awakening. Michael, who is known to have been captured when poachers killed his entire family, sometimes wakes up and signs “Bad people kill gorillas.”
What we do know for sure is that most mammals have a similar sleep cycle to humans, going into a deep sleep stage, in which the brain is much less active, and then into periods of activity called Rapid Eye Movement (REM) sleep, in which dreams occur for humans. That certainly makes it the best guess that other mammals are dreaming, too.
In terms of potential differences, we know that small animals, like mice, go through the sleep stages much more quickly so they would likely be having shorter, more frequent dreams. Elephants have a cycle that is longer than ours, so they would be in deep sleep longer between their dreams. Reptiles and fish don’t have the REM/non REM cycles, so they probably have dreamless sleep.
What do dogs experience when they dream?
Humans dream about the same things they’re interested in by day, though more visually and less logically. There’s no reason to think animals are any different. Since dogs are generally extremely attached to their human owners, it’s likely your dog is dreaming of your face, your smell and of pleasing or annoying you.
We actually know more about cat’s dreams, because one of the earliest sleep researchers, Michel Jouvet, destroyed the tiny area in cat brains that inhibits movements during REM sleep. Cats lay quietly through the other stages of sleep, and when REM began, they leapt up, stalked, pounced, arched their backs and hissed. They looked like they were hunting mice in their dreams.
What does it mean when my pet is asleep and its legs start moving like they are running?
They may well be dreaming they’re running. Common sleep-walking doesn’t occur during dreaming sleep, but a much more vigorous “REM behavior disorder”— a spontaneous version of what Jouvet’s experiments did, is accompanied by dreams, so the more pronounced and fast the movements, the more likely they’re acting out a dream.
Is there any way to give your pet better dreams?
The best way to give ourselves or our children better dreams is to have happy daytime experiences and to get plenty of sleep in a safe and comfortable environment. It’s a good bet this is also best for pets’ dreams.
