Should You Share Your Bed with Your Pet? A Science Backed Look!

Let’s be real—there’s just something adorable about cuddling up with your pet at night. Whether your dog is lying by your feet or your cat is taking over half the pillow, sleeping with our little friends seems like second nature to many pet parents. But while it might feel good, is it really good for you? Or them? The reality isn't cut and dry. It is said that sharing beds with your pet can be soothing—but not without its drawbacks. Let's sort through what science has to offer so that you can make the most informed decision for yourself and your furry roommate.



For many of us, pets are more than just animals—they're emotional comfort, daily companionship, and family. So when bedtime approaches, having them snuggle into bed seems like the right thing to do. This is supported by research. Studies have concluded that individuals tend to feel safer, less nervous, and even emotionally more secure when a pet is present at night. In fact, one study specifically noted that women especially sleep more soundly with a dog in the bed compared to having a human partner. Uncomfortable truth, but for many, relatable. Pets add warmth, comfort, and companionship, especially for those who live alone. So yes, your pup spooning alongside you may indeed be conducive to better sleep—under the proper circumstances.



Now let’s talk about the downside. While pets can make you more relaxed, they’re not exactly known for sleeping through the night. Dogs may snore, bark at noises outside, or change positions multiple times before settling down. Cats? They are notorious for their 2 a.m. hallway sprints. As charming as they are in daylight, at night they can unintentionally sabotage your sleep. Experts caution that even subtle disruptions from a pet can erode your sleep quality over time, leaving you drowsy and less alert the next day. If you are already a light sleeper or someone who has trouble maintaining sleep, this can easily become a dealbreaker.



There’s also the cleanliness issue—something many prefer to ignore. Regardless of how much you adore them, pets bring fur, dirt, dander, and occasionally other unpleasant elements into your bed. Experts and researchers agree that if you are going to share a bed with your pet, their hygiene must be maintained at a high standard. This means frequent baths, regular flea and tick prevention, thoroughly cleaned paws, and changing your bedding on a routine basis. Neglecting any of these can increase the risk of allergens, parasites, and even infections in your sleeping environment. If you suffer from allergies, asthma, or have a compromised immune system, co-sleeping with a pet may not be the safest option. It isn’t about being overcautious—it’s about being responsible.



We often focus so much on how we sleep that we forget our pets have sleep patterns too. And guess what? They can be affected by us. Pets, especially dogs, are highly sensitive to sound and movement. If you’re someone who moves around a lot or checks your phone frequently at night, your pet’s sleep can be disrupted as well. Over time, this may impact their behavior and restfulness. Furthermore, if your pet has existing anxiety or strong attachment tendencies, co-sleeping can reinforce their dependence. Experts suggest that pets who struggle to sleep alone may have trouble coping when boarded or left at home without you—a factor worth considering before turning co-sleeping into a nightly ritual.



There are certain situations where sleeping with your pet might actually benefit both of you. If you live alone and feel safer with a dog nearby, the emotional support could positively affect your sleep. Similarly, if your pet helps ease your anxiety or stress and both of you sleep soundly without disturbing one another, co-sleeping could work well. Another important condition is hygiene. If you’re diligent about cleanliness and your pet is healthy and well-groomed, then sharing your bed could be a safe, comforting experience. It ultimately comes down to personal boundaries and self-awareness.



If you're leaning toward letting your pet sleep with you, certain habits can help create a healthier, more restful environment for both of you. Establish a consistent bedtime routine for you and your pet. Going to sleep at the same time each night can help regulate circadian rhythms and reduce nighttime disturbances. Designate a specific spot for your pet on the bed. Whether it’s near your feet or on a separate blanket, this reduces fur and helps your pet settle in without overtaking your space. Make cleanliness a priority. Daily grooming for your pet, regular bathing, and weekly changes to your bed linens are essential. Don’t forget to stay on top of veterinary visits, vaccinations, and parasite screenings.Finally, observe your pet’s behavior. If they become anxious or overly attached when you’re not around, consider training to encourage more independence.



There’s no one-size-fits-all answer. It truly depends on you, your pet, and your specific lifestyle. If sleeping with your pet makes you feel calm and doesn’t interfere with your rest, there’s no harm in continuing. But if you wake up exhausted, sneeze through the night, or feel like you’re losing sleep over your dog’s tossing and turning, it may be worth reassessing your bedtime arrangement. And don’t worry—your bond won’t weaken if your pet sleeps in their own cozy bed nearby. In fact, sometimes a bit of space makes for an even healthier relationship, both emotionally and physically.


At the end of the day, it’s not about whether sharing your bed with a pet is right or wrong—it’s about whether it’s right for you. Science doesn’t dictate a universal rule; it simply provides insights to help you decide what works best in your unique situation. Whether your dog is your ultimate sleep companion or your cat prefers her plush throne beside the bed, the goal remains the same: sleep peacefully, wake up refreshed, and nurture a connection that lasts—whether or not you’re curled up together under the covers.
