Arguments for letting your dog sleep in your bed
1. Emotional and psychological benefits
-Many owners report reduced anxiety, comfort, and a sense of security when a dog sleeps nearby.
-Studies and expert commentary suggest co-sleeping can increase oxytocin and serotonin, which are linked to bonding and wellbeing.
-Particularly for some groups (e.g. people with anxiety, PTSD, or children), it can improve sleep experience emotionally, even if not always physically.
2. Strengthening the human–dog bond
-Sleeping together is seen as an extension of companionship and can deepen the relationship between owner and dog.
3. Some people genuinely sleep better
-Certain studies (e.g. Mayo Clinic) suggest some people feel more relaxed and secure, which can improve perceived sleep quality.
Arguments against sharing your bed
1. Sleep disruption
-Dogs move, twitch, snore, and change position—this can wake you multiple times a night, especially if you’re a light sleeper.
-Research suggests sleep efficiency can be slightly lower when dogs are in the bed vs just in the room.
2. Hygiene, allergies, and health risks
-Dogs can bring in dirt, pollen, parasites (ticks/fleas), and bacteria, which may affect health.
-For people with allergies, asthma, or weakened immune systems, risks are higher.
3. Behavioural considerations
-Some dogs may develop resource guarding (becoming possessive of the bed).
-It can also create dependency or training issues, especially with puppies.
4. Practical downsides
-Space, overheating, and partner preferences can all make it less comfortable.
What experts generally agree on about dog co-sleeping
-There is no universal rule—it depends on:
…your sleep quality
…your dog’s behaviour and cleanliness
…your health (e.g. allergies)
-For many people, the best compromise is:
…dog in the same room but not the bed, or
clear boundaries (e.g. foot of the bed).
Bottom line- You do You
-Pro camp: better bonding, comfort, mental health benefits
-Against camp: worse sleep, hygiene concerns, occasional behavioural issues
-Reality: it’s highly individual, what works brilliantly for one person can be a nightmare for another
