It’s no secret that our furry friends love their naps. According to the National Sleep Foundation, dogs and cats spend around 15 hours a day snoozing—and depending on their age, breed, and activity level, that number can be even higher. With all that time spent curled up in dreamland, a curious question arises: Do pets dream? And if they do, can they have nightmares?
Let’s explore what science and experience tell us.
The Science Behind Animal Dreams
Our curiosity about animals and their dreams isn’t new—it actually dates back to the 1960s. Researchers began studying sleep in animals by monitoring their brain activity, observing behavior during different sleep stages, and comparing it with how they behave when awake.
It turns out that pets go through multiple stages of sleep just like we do, including REM (Rapid Eye Movement)—the stage associated with the most vivid dreams in humans. During REM sleep, some cats and dogs may twitch their paws, move their eyes, or shift their heads as if chasing something or interacting with another animal. These subtle movements suggest they might be dreaming about activities like playing, exploring, or even hunting.
Yes, Pets Dream—And Sometimes, It’s Not Pleasant
Studies have shown that the brains of cats, dogs, and even rats show patterns during sleep that mirror the ones seen when they’re awake and engaged in activities they enjoy. That means they likely dream about the things they experience daily—good or bad.
So yes, pets can have nightmares. Stressful or scary experiences may resurface during sleep as disturbing dreams. On rare occasions, pets might even wet their bed or display unusual behavior during a nightmare. If it happens once in a while, it may be harmless. But if you notice it frequently, it could signal an issue such as a urinary tract infection—and that’s a good reason to check in with your vet.
How Can You Help a Pet Having a Nightmare?
Seeing your pet unsettled during sleep can be heartbreaking, but the best thing to do is not wake them up suddenly, as this can cause confusion or fear. Instead, be ready to comfort them gently when they wake up on their own.
You can also minimize the likelihood of nightmares by reducing stress in your pet’s daily routine. For example, limit exposure to aggressive animals, or ensure your pet is getting enough of the kind of stimulation they personally enjoy—like walks for dogs or peaceful indoor play for more introverted cats.
Create a Peaceful Sleep Environment
Your pet’s sleeping spot plays a big role in their sleep quality. Ensure they have a comfortable bed in a quiet, cozy corner of your home, away from loud noises or constant activity.
And remember: a day filled with love, exercise, and positive moments can lead to a peaceful night’s sleep. For most pets, a happy, balanced day is the best recipe for a night free of bad dreams.
