Sleeping With Your Dog: Health Facts & Tips

Yes, it can be healthy to sleep in the same bed as your dog, provided you have no severe allergies, your sleep isn’t disrupted, and both you and your pet are healthy. For many people, the comfort and sense of security outweigh the potential downsides, but the answer depends on your personal health, your dog’s behavior, and your sleep hygiene.

Formula

The calculator above estimates a subjective “sleep quality score” out of 10 based on two simple inputs: your typical nightly sleep duration (in hours) and your dog’s weight (in kilograms). The formula is:

Sleep Quality Score = 10 − 0.2 × (Dog Weight in kg) + 0.5 × (Your Sleep Hours − 6)

Where:

• Dog weight (kg) – heavier dogs take up more bed space and may disturb your sleep more.
• Your sleep time (hours) – the more sleep you get, the better you feel; the formula rewards sleeping more than 6 hours.
• Score – a rough indicator from 0 (very poor sleep) to 10 (excellent). It is not a medical measurement; it’s a heuristic to help you think about trade-offs.

Worked Example

Using the default values: you sleep 7 hours, and your dog weighs 20 kg (about 44 lbs).

1. Start with 10.
2. Subtract 0.2 × 20 = 4.0 → 10 − 4.0 = 6.0.
3. Add 0.5 × (7 − 6) = 0.5 × 1 = 0.5 → 6.0 + 0.5 = 6.5.

Your estimated sleep quality score is 6.5 out of 10. That suggests moderate sleep quality – not ideal, but not terrible. If you slept 8 hours with a 10 kg dog, the score would be 10 − 2 + 1 = 9, which is much better.

The Background: Why People Sleep With Dogs

Co-sleeping with dogs is not new. Dogs have shared sleeping spaces with humans for thousands of years, originally for warmth and protection. In modern times, surveys suggest that roughly half of pet owners allow their dog in the bedroom, and about a third share the bed itself. The practice is more common among single people, those without children, and people who view their dog as a family member.

The rise of “pet humanization” has made co-sleeping more mainstream. Many owners report that sleeping with their dog reduces anxiety and makes them feel safer. Some even say they sleep better with their dog than alone. But the scientific evidence is mixed, and the health effects depend heavily on the individual.

How It Affects Your Sleep: The Good and the Bad

Research on co-sleeping with dogs has produced conflicting results. A 2017 study from the Mayo Clinic found that people who slept with a dog in the bedroom actually maintained better sleep efficiency than those who slept with a cat or another human. However, when the dog was on the bed itself, sleep was more disrupted, especially if the dog moved around.

Potential benefits:

• Emotional comfort: The presence of a dog can lower stress hormones like cortisol and increase oxytocin, the “bonding” hormone.
• Sense of security: Many people feel safer with a dog nearby, which can reduce nighttime anxiety.
• Warmth: A dog’s body heat can be soothing in cold weather.

Potential drawbacks:

• Movement and noise: Dogs shift, snore, and sometimes dream-run, causing micro-awakenings you might not even remember.
• Allergies and asthma: Dog dander and fur can worsen respiratory symptoms, especially if you have allergies or asthma.
• Hygiene concerns: Dogs can bring in dirt, parasites, and occasionally zoonotic diseases (though rare in healthy indoor pets).
• Space issues: A large dog can take up more room than a human, leading to poor posture and back pain.

How to Choose What’s Right for You

Deciding whether to share your bed with your dog is a personal choice. Here are practical factors to consider:

• Your health: If you have allergies, asthma, or a weakened immune system, it’s safer to keep the dog off the bed.
• Your sleep quality: If you already struggle with insomnia or light sleep, a restless dog may make it worse.
• Your dog’s temperament: Puppies, elderly dogs, or dogs with separation anxiety may need to be near you, but they also may wake frequently.
• Your partner: If your partner is allergic or doesn’t want the dog, it’s a relationship decision too.
• Bed size: A king-size bed can accommodate a small dog easily; a twin bed with a 40 kg dog is likely to cause problems.

Start with a trial period. Let your dog sleep on the bed for a week, then evaluate how you feel. If you’re waking up tired or sore, it may be time to transition the dog to a crate or a dog bed on the floor.

Common Problems and How to Solve Them

Even if you love sleeping with your dog, issues can arise. Here are common ones and practical solutions:

• Dog takes up too much space: Train your dog to sleep at the foot of the bed, or use a body pillow as a barrier.
• Dog wakes you up at night: Make sure your dog gets plenty of exercise and goes to the bathroom right before bed. If the dog is restless, consider a calming supplement (after consulting your vet).
• Allergies: Wash your bedding weekly in hot water, use a HEPA air purifier, and groom your dog regularly to reduce dander.
• Dog is too hot: Dogs have a higher body temperature than humans. Use lighter blankets and keep the room cool.
• Dog growls or guards the bed: This is a behavioral issue that should be addressed with positive reinforcement training. Never punish the dog; consult a professional trainer if needed.

Comparisons: Bed, Bedroom, or Crate?

There’s a spectrum between sharing your bed and having the dog sleep in another room. Each has pros and cons:

• In your bed: Maximum bonding and comfort, but highest risk of sleep disruption and allergies.
• In your bedroom, but on a dog bed: A good compromise. You get the security and companionship, but the dog has its own space. Many sleep experts recommend this option.
• In a crate in your bedroom: Ideal for puppies or dogs that need confinement. It provides safety and helps with house-training.
• In another room: Best for people with severe allergies or light sleepers. Some dogs do fine alone; others may develop separation anxiety.

There’s no one-size-fits-all answer. The right choice depends on your dog’s age, health, and training, as well as your own needs.

Safety and Hygiene Considerations

While the risk is low for healthy adults, there are some safety points to keep in mind:

• Very young children: It’s generally advised not to let infants or toddlers sleep with a dog, due to risks of accidental suffocation or injury. The American Academy of Pediatrics recommends that babies sleep alone in a crib.
• Parasites and infections: Keep your dog on regular flea, tick, and heartworm prevention. Wash your hands after touching the dog, and wash bedding frequently.
• Injuries: A dog that startles from a dream might scratch you. If you have mobility issues, a dog tripping you at night is a fall risk.
• Zoonotic diseases: These are rare in healthy indoor pets, but people with compromised immune systems should be extra cautious.

If you have any chronic health condition, talk to your doctor about whether co-sleeping with a pet is safe for you.

Frequently Asked Questions

Does sleeping with my dog make my allergies worse?

Yes, it can. Dog dander (dead skin cells) and saliva are common allergens. If you’re allergic, having the dog on your bed exposes you to higher concentrations all night. Using hypoallergenic bedding, bathing your dog weekly, and keeping the dog off your pillow can help, but the most effective solution is to keep the dog out of the bedroom entirely.

Can my dog get too hot sleeping under the covers?

Dogs can overheat more easily than humans because they don’t sweat the same way. If your dog is under heavy blankets, watch for panting, restlessness, or trying to escape. Most dogs will move if they’re too hot, but brachycephalic breeds (like pugs) are more vulnerable. Keep the room cool and provide a cool spot for your dog to move to.

Will sleeping with my dog cause behavioral problems?

Not necessarily. Sleeping together doesn’t cause aggression or dominance issues. However, if your dog becomes possessive of the bed, that’s a separate training issue. In general, co-sleeping strengthens your bond and can actually reduce anxiety in dogs.

Is it safe for my dog to sleep in my bed after surgery?

It depends on the surgery and your dog’s size. After surgery, your dog may be disoriented or in pain, and could accidentally hurt you or itself. It’s usually safer to provide a quiet, confined space on the floor where the dog can’t jump or fall. Follow your veterinarian’s specific post-operative instructions.

How do I transition my dog out of my bed?

Gradual change works best. Start by placing a dog bed on the floor next to your bed. Reward your dog for lying there. Over several nights, move the dog bed farther away. Be consistent and ignore whining (unless it’s due to anxiety). You can also use a crate with a comfortable blanket. It takes patience, but most dogs adapt within a week or two.
