Quick Answer: Whether your pet should sleep in your bed depends on your sleep quality and allergies. A Mayo Clinic study found that having a dog in the bedroom kept sleep quality good, while a dog on the bed slightly lowered sleep efficiency. If you sleep well and have no allergies, there is no medical reason to stop.
Brad Grose, Owner, Mattress Miracle: "We have been helping Brantford families sleep better since 1997. Every customer gets personal attention, honest advice, and the kind of follow-up service you just do not get from big box stores."
About 56% of pet owners share their bed with their pet. Research shows mixed results: some people sleep better with their pet nearby (comfort, security, reduced anxiety), while others experience disrupted sleep (movement, allergies, space competition). The honest answer is that it depends on your pet, your sleep quality, and your health. If you sleep well with your pet and have no allergies, there is no medical reason to stop. If your sleep quality is poor or you have allergies, the pet may need their own sleeping spot. A compromise: pet bed next to your bed provides proximity without disruption.

What the Research Says
A Mayo Clinic study found that people who slept with their dog in the bedroom (but not on the bed) maintained good sleep quality. Those with the dog actually on the bed had slightly lower sleep efficiency. However, a subsequent study found that many people report better subjective sleep quality with a pet, likely due to the comfort and security they provide. The key finding: pet in the bedroom is fine for most people; pet on the bed disrupts some but not all sleepers.
Dogs vs Cats in Bed
Dogs: Tend to sleep in longer stretches that align with human sleep. Larger dogs take up more space and can restrict your movement. They may adjust positions 2-3 times per night, potentially waking you. Most dogs prefer to sleep at the foot of the bed or beside your legs. Cats: Are more disruptive to sleep. Cats are crepuscular (most active at dawn and dusk), which means they may wake you early. They move more frequently during the night. However, a purring cat has been shown to reduce stress and blood pressure. The vibration frequency (25-50 Hz) is in the range used therapeutically for bone healing and pain relief. Whether a cat improves or disrupts your sleep depends largely on the individual cat temperament.
Benefits of Sleeping With Your Pet
- Reduced anxiety: Physical contact with a pet releases oxytocin and lowers cortisol. For people with anxiety or PTSD, a pet in the bed can significantly improve sleep quality
- Security: Dogs in particular provide a sense of safety. People who live alone often report significantly better sleep with their dog present
- Warmth: A pet generates body heat. In cold Canadian winters, a warm pet can be a genuine comfort (and reduce heating costs slightly)
-
Routine: Pets create consistent sleep schedules. Dogs need to go out before bed and want
breakfast at the same time every morning, reinforcing healthy sleep timing - Bond: Nighttime is a significant portion of the day. Sharing sleep space strengthens the human-animal bond, which has documented mental health benefits
Drawbacks and Health Concerns
When Pets Should Not Be in the Bed
Allergies: Pet dander, saliva, and outdoor allergens (pollen, dust) that pets carry into bed can worsen allergies and asthma. If you have allergies, pet-free bedding and bedroom is recommended. Allergen-proof mattress protectors help but do not eliminate the issue if the pet is on the bed.
Sleep disruption: If you are waking multiple times because your pet moves, takes too much space, or makes noise, your sleep quality is suffering. Track your sleep with or without your pet for a week to compare objectively.
Mattress damage: Claws, accidents, drool, and fur accumulation damage mattresses. A waterproof mattress protector is essential if your pet shares the bed. Without one, the mattress lifespan may be shortened by 2-3 years.
Parasites and hygiene: Pets can carry fleas, ticks, and intestinal parasites into the bed. Keep pets on regular parasite prevention. Wash bedding weekly in hot water if pets sleep on the bed.
Relationship impact: If one partner wants the pet in bed and the other does not, the pet is disrupting the relationship. The human partner should be prioritized. A pet bed next to the bed is a good compromise.
Making It Work
If You Choose to Share the Bed
(1) Waterproof mattress protector: Non-negotiable. Protects against accidents, drool, and allergens penetrating the mattress. (2) Wash bedding weekly in hot water. Pet hair, dander, and outdoor allergens accumulate fast. (3) Keep pets clean: Regular grooming, paw wiping after outdoor time, and parasite prevention. (4) Size up your mattress:> If a medium-sized dog shares your queen bed, you effectively have a full-size sleeping surface. Consider a king if space is an issue. (5) Establish boundaries: Train pets to sleep at the foot of the bed rather than on pillows (where allergens are closest to your face and airway). (6) Pet bed backup: Have a comfortable pet bed in the bedroom so the pet has an alternative when needed. (7) Regular vet checkups: Ensure your pet is healthy and parasite-free if sharing your sleep space.

Will my pet ruin my mattress?
Without a protector, yes, over time. Pet accidents, drool, fur, and claw scratches all damage the mattress surface and interior. A quality waterproof protector prevents 95% of the damage. With a protector, the mattress should last its normal lifespan.
Is it unhealthy to sleep with pets?
For most healthy adults with parasite-protected pets, no. The bonding and anxiety-reduction benefits often outweigh the minor hygiene concerns. People who are immunocompromised, have severe allergies, or have untreated sleep disorders should consult their doctor.
How do I get my pet out of the bed?
Place a comfortable, warm pet bed beside your bed. Reward the pet for using it. Be consistent. It may take 1-2 weeks of reinforcement. Most pets accept the transition well if the alternative sleeping spot is comfortable and close to you.
My dog takes up the whole bed. What do I do?
Consider a king-size mattress if feasible. Train the dog to sleep at the foot of the bed. Use a body pillow as a gentle boundary. Or, provide a comfortable large dog bed beside your bed. Some couples find that a pet bed on the floor is the happiest compromise for everyone.
