For many pet owners, deciding whether or not to let their dog sleep in the bed is a nightly debate. Some feel that sharing a bed with their dog brings comfort, relaxation, and emotional support. Others worry about hygiene, sleep disruptions, or whether it reinforces inappropriate behavior.

However, a growing body of research indicates that sleeping with your dog may come with several surprising advantages — both psychological and physiological.

One noteworthy study conducted at the Center for Sleep Medicine at the Mayo Clinic in Scottsdale, Arizona, examined the sleep patterns and preferences of 150 adults. According to findings reported by multiple reputable outlets, including the Daily Mail, 56% of participants shared their bed or bedroom with a dog or cat, and 41% of those individuals reported better sleep because of their pets.

While results vary from person to person, science suggests there are meaningful benefits associated with sleeping alongside your dog. Below are eight research-supported reasons why allowing your dog on the bed may improve your well-being, strengthen your bond, and enhance the quality of your rest.

1. Emotional Comfort Before Sleep

One of the most immediate benefits of having a dog near you at night is the sense of comfort it provides. Dogs are known for their loyalty and affection, and simply having them close can soothe feelings of loneliness, nervousness, or restlessness.

Studies exploring the human–animal bond consistently show that interacting with dogs increases the release of oxytocin, often called the “bonding hormone.” This hormone supports emotional stability, lowers stress levels, and helps create a sense of calm. As a result, many people find that cuddling or resting beside their dog at night elevates their mood and prepares their mind for rest.

For individuals who experience nighttime anxiety, intrusive thoughts, or emotional stress, a dog’s presence can serve as a grounding force that makes bedtime feel safe and comforting.

2. Dogs Can Help You Fall Asleep Faster

Difficulty falling asleep is a common issue around the world. Research shows that having a dog in the bed may help reduce sleep latency — the time it takes to transition from wakefulness to sleep.

According to animal-assisted therapy studies, dogs help decrease levels of cortisol, the body’s primary stress hormone. Lower cortisol levels promote relaxation, which helps you drift off more easily.

Additionally:

• Dogs often have a naturally steady, rhythmic breathing pattern.

• Their quiet presence can act similarly to white-noise therapy.

• Feeling secure helps the brain transition into a restful state more quickly.

In essence, a relaxed body and calm environment make it easier to fall asleep, and dogs often contribute to both.

3. Reduced Stress and Anxiety Levels

Dogs are widely recognized for their therapeutic value. Their ability to reduce stress has been documented in various contexts — hospitals, therapy programs, universities during exam seasons, and crisis-response situations.

Sleeping near your dog may help lower:

• Daily accumulated stress

• Anxiety related to nighttime

• Physiological indicators of stress such as elevated heart rate

The Mayo Clinic study found that many participants felt more relaxed when their dog was nearby. This reduction in stress is significant because chronic stress not only disrupts sleep but also impacts long-term health.

Even the simple act of petting a dog before sleep stimulates the release of serotonin, a neurotransmitter that regulates mood, happiness, and restfulness.

4. Additional Warmth During Cold Months

Dogs naturally have a higher resting body temperature than humans. Many breeds retain heat well, making them an effective — and very cuddly — source of extra warmth during winter.

People who share a bed with their dogs often note:

• Warmer sleeping conditions

• Less need for heavy blankets

• A cozy, comforting sleeping atmosphere

This benefit is especially appreciated in colder climates or in seasons where temperatures dip at night.

5. Lower Risk of Depression

Pets provide unconditional love, emotional support, and a sense of purpose — all of which can positively impact mental health.

Studies show that interacting with dogs increases dopamine and oxytocin levels, both of which play a role in combating symptoms of depression. Having your dog close at night may:

• Decrease feelings of loneliness

• Improve emotional well-being

• Reinforce your sense of connection

For individuals who are grieving, recovering from trauma, or managing depression, a dog’s presence can feel stabilizing and deeply reassuring.

6. A Greater Sense of Safety and Security

Even when they aren’t acting as guard dogs, many pets provide a psychological sense of protection.

Knowing that your dog is nearby can:

• Reduce nighttime fears

• Help you feel more secure when sleeping alone

• Alert you if something unusual occurs

Dogs have excellent hearing and are often the first to notice unfamiliar sounds or movements. This “built-in alarm system” gives many owners peace of mind and may contribute to deeper, more restful sleep.

A sense of safety is fundamental for quality sleep, and dogs often create that environment naturally.

7. Benefits for Your Dog’s Emotional Health

The advantages of co-sleeping aren’t limited to humans — dogs benefit as well.

For most dogs, you are their primary source of companionship and comfort. Sleeping near you reinforces:

• Bonding

• Security

• Trust

• Emotional stability

Many dogs experience separation anxiety, especially rescues or those with past trauma. Sleeping beside you can help reduce stress, improve overall behavior, and contribute to positive mental well-being.

Studies also indicate that dogs who sleep near their owners often display stronger attachment and reduced fear responses during the day.

8. Sleeping With Your Dog May Boost Cognitive Health

Oxytocin and serotonin — hormones commonly associated with positive interactions with dogs — also affect brain function. These chemicals contribute to:

• Improved emotional regulation

• Increased sense of security

• Enhanced relaxation

• Better psychological resilience

A study analyzing oxytocin’s role in the brain found that increased levels can promote stability, reduce stress, and improve overall cognitive performance. When your dog sleeps beside you and helps you relax, this effect may continue throughout the night.

In addition, better sleep quality itself is linked to:

• Sharper concentration

• Stronger memory

• More stable mood

• Improved long-term brain health

Simply put, feeling calm and secure with your dog nearby sets the stage for healthier sleep cycles, which benefit your brain in countless ways.

Is Sleeping With Your Dog Right for You?

While there are many benefits, sharing a bed with your dog isn’t ideal for everyone. Consider the following:

✔ Good Reasons to Allow Co-Sleeping

• Your dog helps you feel calm.

• You enjoy the emotional bond.

• Your sleep quality improves when your dog is nearby.

• You feel safer with your dog in the room.

✔ Reasons to Avoid It

• You have allergies or asthma.

• Your dog disrupts your sleep by moving, barking, or snoring.

• You prefer strict boundaries or training routines.

• Your dog has behavioral issues that need addressing first.

Ultimately, the best choice is the one that supports your health, happiness, and lifestyle — and your dog’s.

Final Thoughts

Growing research highlights the emotional, psychological, and physical benefits of sharing your bed with your dog. While it may not be suitable for all households, many people find comfort, improved sleep, and a stronger bond with their pets by allowing them under the covers.

If your dog is clean, well-behaved, and brings you calmness and joy, sharing your bed might be more beneficial than you ever realized.
