What happens when they sleep"},"content":{"rendered":"\n

Have you ever watched your dog or cat while they sleep? One moment they’re peacefully snoring, and the next, their paws begin to twitch slightly as if they\u2019re running a marathon. Maybe they let out a quiet whimper, bark in their sleep, or wiggle their whiskers. In these moments, every pet owner asks themselves the same question: do my pets dream?<\/strong> What’s going on in their heads when they sink into the world of dreams? It\u2019s one of the most endearing questions about the relationship between humans and animals. And the answer is much deeper than you might imagine. We’ll be discussing all this and more, next on Tvaryny<\/a>.<\/p>\n\n\n\n

Yes, they do dream! And science confirms it<\/h2>\n\n\n\n
\"\"<\/figure>\n\n\n\n

To put it simply: yes, scientists are completely confident that dogs, cats, and many other mammals dream. This confidence isn’t based on cute internet videos, but on serious research into the structure of the brain and its activity during sleep. The brains of our four-legged friends are surprisingly similar to human brains, especially in the part responsible for sleep.<\/p>\n\n\n\n

To understand how this works, we need to break down the main phases of sleep in animals<\/strong> (and in humans, too). Broadly, sleep is divided into two main stages:<\/p>\n\n\n\n

    \n
  • Non-REM sleep (NREM):<\/strong> This is the phase of deep sleep when the body is most relaxed, breathing is even, and the brain is resting. During this time, the body’s physical strength is restored.<\/li>\n\n\n\n
  • REM sleep (Rapid Eye Movement):<\/strong> The name says it all \u2013 in this phase, the eyeballs move quickly under closed eyelids. It’s during this time that the brain becomes extremely active, almost as if it’s awake. And it’s in the REM phase that we (and our pets) experience the most vivid and emotional dreams.<\/li>\n<\/ul>\n\n\n\n

    Researchers who have studied the brain activity of dogs and cats using an electroencephalogram (EEG) have seen a clear pattern: the brainwave patterns during REM sleep in animals are practically identical to those in humans. This has become the main evidence that their brains are also “playing a movie” during this time.<\/p>\n\n\n\n

    The Pons: A natural “safety switch” for nocturnal adventures<\/h2>\n\n\n\n

    So why, if the brain is active and the dreams are so vivid, doesn’t your dog jump up and chase an imaginary squirrel around the house? We have a special part of the brainstem called the pons<\/em> to thank for that. During REM sleep, it sends signals that effectively paralyse the body’s large muscles. This is a natural safety mechanism that prevents us and our pets from physically acting out our dreams.<\/p>\n\n\n\n

    This is why when you see your dog twitching in their sleep<\/strong>, wiggling their paws, or making sounds, it means the pons hasn’t fully “turned off” the muscles. The small contractions break through, and we become witnesses to their nightly adventures.<\/p>\n\n\n\n

    What do dogs dream about?<\/h2>\n\n\n\n
    \"\"<\/figure>\n\n\n\n

    Alright, they dream, but what exactly do they dream about?<\/strong> Researchers from Harvard Medical School, including Dr Deirdre Barrett, state that a dog’s dreams are most likely related to their daily experiences. They aren’t dreaming about quantum physics or politics. They’re dreaming about familiar things:<\/p>\n\n\n\n

      \n
    • Favourite activities:<\/strong> Running in the park, playing with a ball, chasing a squirrel or a sparrow, or swimming in a river.<\/li>\n\n\n\n
    • Pleasant smells:<\/strong> The aroma of your dinner, the smell of their favourite treats, or a familiar path in the woods.<\/li>\n\n\n\n
    • Important people (that’s you!):<\/strong> The most important thing in a dog’s life is their owner. It’s very likely that a significant portion of their dreams is dedicated to you: your face, your voice, your smell, your shared walks and hugs. When your dog wags their tail in their sleep, they might be dreaming of you coming home from work.<\/li>\n<\/ul>\n\n\n\n

      Scientists have even been able to roughly determine when a dream begins. In the average dog, the REM phase occurs about 20 minutes after they fall asleep. You might notice their breathing becoming irregular and shallow\u2014this is the first sign that a dream has started. Then come the same twitches of the paws, ears, and eyes.<\/p>\n\n\n\n

      The mysterious dreams of cats: The hunt continues even in sleep<\/h2>\n\n\n\n
      \"\"<\/figure>\n\n\n\n

      And what about cats?<\/strong> Their dreams also reflect their instincts and daily concerns. Legendary sleep researcher Michel Jouvet conducted an experiment in the mid-20th century where he surgically “disconnected” the pons in cats. The result was astonishing. When the cats entered the REM sleep phase, they didn’t lie still. They got up, hissed, arched their backs, and lunged at invisible prey\u2014in short, they completely recreated their hunting behaviour.<\/p>\n\n\n\n

      This provided a clear understanding: cats mostly dream about hunting. They might dream of mice, birds, sunbeams, or your hand under the duvet. Their dreams are full of stalking, pouncing, and triumph. Of course, they also dream of pleasant things: being petted, basking in the sun, or enjoying their favourite food.<\/p>\n\n\n\n

      How to ensure sweet dreams for your pet: practical tips<\/h2>\n\n\n\n
      \"\"<\/figure>\n\n\n\n

      Understanding that our pets dream places a certain responsibility on us. We can influence the quality of their sleep and, consequently, their dreams. Here are a few tips on how to improve your pet’s sleep<\/strong>:<\/p>\n\n\n\n

        \n
      1. Create a safe and comfortable place to sleep.<\/strong> A dog or cat should have its own bed, crate, or soft spot where no one will disturb them. This is their fortress of calm.<\/li>\n\n\n\n
      2. Stick to a daily routine.<\/strong> Regular walks, feeding, and playtime at the same time help to set your pet’s body clock. Stability equals peace.<\/li>\n\n\n\n
      3. Provide enough stimulation during the day.<\/strong> A good night’s sleep is the result of a full day. Active walks, puzzle toys, and interaction with you fill their day with positive emotions that later turn into pleasant dreams. A dog that has been bored all day will sleep worse.<\/li>\n\n\n\n
      4. Do not wake a pet that is dreaming!<\/strong> This is the most important rule. Even if you think your pet is having a nightmare (they’re whimpering or twitching their paws), don’t wake them up. A sudden awakening from a deep REM phase can be very frightening for an animal. They may not immediately understand where they are or who you are and might instinctively bite or scratch. Just stay close and wait for them to calm down on their own.<\/li>\n<\/ol>\n\n\n\n

        Frequently Asked Questions (FAQ)<\/h2>\n\n\n\n

        Do animals have nightmares?<\/strong><\/p>\n\n\n\n

        Yes, it’s quite likely. If they can have dreams about good things, they can also have them about bad things. Nightmares can be related to past negative experiences (especially in rescued animals), stress, or fear. If your pet often wakes up frightened, whimpering, or trembling, you should analyse their current state. Something might be bothering them, and it may be worth consulting a vet or a pet behaviourist.<\/p>\n\n\n\n

        Are dreams different in puppies\/kittens and adult animals?<\/strong><\/p>\n\n\n\n

        Yes! Puppies and kittens spend much more time in the REM phase than adults. This is because their brains are actively processing the huge amounts of new information they’ve received during the day. During sleep, this information is sorted and consolidated. Therefore, puppies and kittens dream more often and may be more “active” in their sleep.<\/p>\n\n\n\n

        Does the frequency of dreams depend on the breed or size of the animal?<\/strong><\/p>\n\n\n\n

        There’s an interesting pattern: small dog breeds like Chihuahuas or Toy Terriers dream more often, but their dreams are shorter (about 1-2 minutes every 10 minutes). Large breeds, such as Great Danes or Saint Bernards, dream less frequently, but their dreams are longer (5-10 minutes every 60-90 minutes).<\/p>\n\n\n\n

        Conclusion<\/h2>\n\n\n\n

        The world of our pets’ dreams is another proof of how complex and emotional they are. Their ability to dream blurs the line between “just an animal” and a full-fledged family member with their own inner world. By observing a sleeping cat or dog, we see not just a physiological process, but an echo of their day, their joys, fears, and their love for us.<\/p>\n\n\n\n

        So, the next time you see your friend’s paws twitching in their sleep, smile. They are probably running through a sunny meadow, playing with their favourite ball, or, best of all, dreaming of you. And that, perhaps, is the best proof of your incredible bond.<\/p>\n","protected":false},"excerpt":{"rendered":"
