13 Scientific Benefits of Sleeping With Your Dog

Is sleeping with your dog a good idea? Science says yes!
By The Bark Editors, June 2019, Updated June 2021

There is an active debate in the pet community about whether or not co-sleeping with your dog is best practice. Some studies show that sleeping with your dog can result in a bad night’s sleep.

However, there are numerous other studies that tout the benefits of letting your dog sleep in the bed with you. For example, sleeping with your pup has many mental benefits such as an increased feeling of safety and comfort. People suffering from PTSD found that sleeping with their pet helped diminish nightmares.

There are physical benefits as well, like the fact that sleeping with your dog releases oxytocin in the brain. This is the chemical that’s released when a person falls in love, or when they are around their baby. The chemical promotes theta brainwaves which are associated with REM sleep. This means it’s likely that you’re sleeping deeper when sleeping with your pet. The chemical also mitigates anxiety and stress, which can help you sleep better.

Petting and touching your dog can even help lower your blood pressure. This not only happens during the waking hours, but when you sleep with your dog too.
