Have you ever wondered if dogs dream? Meet Luna, a lovable labradoodle who might just have some interesting dreams of her own. Dogs are pretty smart creatures. They miss us when we’re not around, understand some of our words, and even have their own personalities. On average, dogs sleep about 14 hours a day. So, what happens when they sleep? Do they dream like we do?
When humans sleep, we go through different stages. First, there’s light sleep, where we can wake up easily. Then comes deep sleep, and finally, there’s rapid eye movement (REM) sleep. During REM sleep, our eyes move quickly, and this is when we’re most likely to dream. Scientists have discovered that animals, including dogs, go through similar sleep cycles.
Researchers at MIT conducted an interesting study with rats. They trained the rats to run around a circular track for a food reward. By monitoring the rats’ brains while they were awake and asleep, scientists found something fascinating. During REM sleep, the rats’ brain activity was similar to when they were running on the track. It was as if they were dreaming about their track adventures!
Most land mammals, including dogs, experience REM sleep. You’ve probably seen a dog twitching or moving its paws while sleeping. This is a sign that they might be dreaming. But what do dogs dream about? Based on their daily activities, dogs might dream about chasing squirrels, playing with their favorite toys, or even spending time with their owners.
Interestingly, the size of a dog can affect how often it dreams. Smaller dogs, like toy poodles, might dream every 10 minutes, while larger dogs, like Irish wolfhounds, might dream once every hour or two. This means that little dogs might have more frequent dream adventures!
Even long ago, people wondered about animal dreams. Aristotle, a famous philosopher, wrote that not only humans but also animals like horses and dogs dream. He was onto something! We now know that dogs can have dreams, and sometimes even nightmares. They might bark or move in their sleep, showing that they’re dreaming.
While we can’t ask dogs about their dreams, scientists believe that dogs do dream, and their dreams are likely based on their daily experiences. Whether they’re dreaming about chasing a ball or spending time with their favorite human, it’s clear that dogs have their own dream worlds. So next time you see a dog sleeping, imagine the adventures they might be having in their dreams!

Imagine you are Luna, the labradoodle. Write a dream diary entry describing an exciting dream adventure you might have. Think about your favorite activities and how they could turn into a dream. Share your entry with the class and discuss what you think dogs dream about.
Conduct a simple experiment to observe your own sleep cycle. Keep a journal for a week, noting the time you go to bed and wake up. Try to remember any dreams you have and write them down. Compare your findings with the sleep cycles of dogs and discuss the similarities and differences.
Create an artwork depicting what you think a dog’s dream might look like. Use any medium you like, such as drawing, painting, or digital art. Consider including elements like chasing a ball or playing with other dogs. Present your artwork to the class and explain your creative choices.
In groups, create a short role-playing game where each student acts as a dog experiencing a dream. Decide on a scenario, such as a day at the park or a trip to the beach. Act out the dream, incorporating elements of what dogs might experience in their dreams. Reflect on the activity and discuss what you learned about dog dreams.
Research another animal that experiences REM sleep and dreams, such as cats or elephants. Prepare a short presentation for the class, including interesting facts about the animal’s sleep patterns and what scientists believe they might dream about. Compare these findings to what you learned about dogs.
Sure! Here’s a sanitized version of the transcript:

[MUSIC PLAYING] This is Luna. You all know Luna. She’s my adorable labradoodle. I might be a little biased, but I think that dogs are quite clever. Research has shown that dogs miss us when we’re gone, they can understand our language, and they can have optimistic or pessimistic personalities. On average, dogs sleep for 14 hours a day, and when I see Luna sleeping, I often wonder, do dogs dream? You know, like humans do.
I’ve mentioned before that when humans sleep, we cycle through stages of light and deep sleep. The first and second stages are light sleep, and we can be woken up easily. When you reach the third stage, you enter deep sleep, and following that is rapid eye movement (REM) sleep, where your eyes actually move back and forth, and you’re most likely to dream. Researchers have found that animals go through the same series of sleep cycles as we do, and some researchers dug a little deeper.
One study at MIT trained rats to run around a circular track for a food reward. Researchers monitored their brains during that task and again when they were sleeping. When the rats entered REM sleep, researchers observed that half of their REM episodes showed the same unique brain activity as when they were running along the track, awake. Their memories were even replayed at about the same speed. In fact, their brain activity, asleep and awake, was so similar that the researchers said they could reconstruct where the rat was on the track and whether it was running or walking.
It’s generally thought that sleep allows us to consolidate and encode memories to learn things. So the rats were learning about that circular track, and a later study, also at MIT, found that the visual areas of rats’ brains are active in dreaming as well as their memory areas, suggesting that animals dream in pictures too. In fact, most land mammals experience REM sleep, whether it’s those mice dreaming of cheese or us dreaming about pizza.
You’ve probably seen a dog in REM sleep before. In dogs, rapid eye movement sleep is accompanied by various movements. They twitch their noses, move their mouths, and often look like they’re running or digging. So I wonder, what would dogs dream about?
A new study has found that squirrels are meant to be chased. It’s their role in the ecosystem. Science suggests that the secret to good health is 10 Milk-Bones a day; that’s more than previously thought. Researchers suggest that you’re a really good dog, Luna. Yep, I’m talking to you.
Even though we can’t ask dogs, based on human brain activity and what we’ve observed in animals, we’re pretty sure that dogs do dream, and their dreams are based on their daily activities. Whether it be chasing chipmunks, their food, or maybe they even dream about their owners. Interestingly, the smaller a dog is, the more it will dream. A toy poodle may dream once every 10 minutes, while an Irish wolfhound may dream once every hour or two.
In his work, The History of Animals, Aristotle wrote that it would appear that not only do humans dream, but so do horses, dogs, and other animals. Dogs show their dreaming by barking in their sleep. And Aristotle was pretty close to the truth. We know now that dogs can have nightmares, they can sleep hunt, sleepwalk, and even sleep pounce. So while we can say that dogs do dream, we can’t say whether they know their dreams are dreams or if they remember them in the morning. What do you think, Luna?
[MUSIC PLAYING] If you want more dog-related science, follow me over to D News where I ask, can dogs be pessimists? And subscribe to Braincraft for more informative videos every week. Can they self-report? Is the water in their bowl half empty or half full? Researchers at the University of Sydney looked into this in a study using 40 dogs of different breeds. What do you think, Luna? Luna doesn’t seem to care.
