In the quest for better sleep, people often ask if they should share their bed with a pet. Before we get to that, let’s take a moment to ponder the flip side:
Is sleeping with you good for your pet?
“I love that we’re reversing the question,” said Dr. Dana Varble, the chief veterinary officer for the North American Veterinary Community. “In general, it is a very good thing for animals to sleep with their people.”
Pets who share their human’s bed tend to have a “higher trust level and a tighter bond with the humans that are in their lives. It’s a big display of trust on their part,” Varble said.
“Dogs and cats who are more closely bonded with their humans get additional health benefits, including increases in beneficial neurotransmitters such as oxytocin and dopamine, the feel-good hormones,” she added.
Is it just dogs and cats who benefit from human bed partners? Yes, Varble said, with a “very, very few exceptions.”
“I have one owner who has a meticulously groomed pot-bellied pig who sleeps at the foot of their bed,” she said. “It’s an indoor pig named Norbert — pot-bellied pigs are almost like dogs because they’re very social.” (Norbert even has his own Instagram account.)
Pros and cons for humans
With that important matter out of the way, let’s turn to you — is it good for you to sleep with a pet? Experts have traditionally said no because you might not get quality shut-eye.
“Animals may move, bark and disrupt sleep. Sleep in dogs (and cats) is not continuous and they will inevitably get up and walk on the bed, stepping on people. All of that activity will lead to sleep fragmentation,” said Dr. Vsevolod Polotsky, director of sleep research and a professor in the department of medicine at Johns Hopkins University School of Medicine.
These “microawakenings,” which can happen without your awareness, “are disruptive because they pull you out of deep sleep,” said Kristen Knutson, an associate professor of neurology and preventive medicine at Northwestern University’s Feinberg School of Medicine. “They have been associated with the release of the stress hormone, cortisol, which can make sleep even worse.”
That may be true for many of us, but recent studies have shown that pets in the bedroom could be beneficial for some of us.
“People with depression or anxiety may benefit from having their pet in the bed because the pet is a big pillow, a big blanket, and they may feel that snuggly, cuddly, furry creature decreases their anxiety,” said sleep specialist Dr. Raj Dasgupta, an assistant professor of clinical medicine at the Keck School of Medicine at the University of Southern California.
Data gathered in 2017 from the Mayo Clinic’s Center for Sleep Medicine in Phoenix found over half of pet owners seen in the clinic allowed their pet to sleep in the bedroom — and the majority found their pet “unobtrusive or even beneficial to sleep.”
About 20% however, did believe their furry friends made their slumber worse.
Another 2017 study put sleep trackers on dogs and their humans to measure the quality of repose for both. People who had their dogs in their bedroom got a decent night’s rest (and so did the dogs), the research team found.
However, sleep quality declined when people moved their dog from the floor to the bed.
Children may benefit from sleeping with a pet as well. A 2021 study asked adolescents ages 13 to 17 to wear sleep trackers for two weeks and then undergo a state-of-the-art sleep test. About a third of the kids slept with a pet, the study noted, which didn’t appear to affect the quality of their rest.
“In fact, frequent co-sleepers showed similar sleep profiles to those who never slept with pets,” the authors wrote.
“All of this suggests that having pets in the bed or bedroom is not necessarily bad,” said Dr. Bhanu Prakash Kolla, a sleep medicine specialist in the Center for Sleep Medicine at the Mayo Clinic in Rochester, Minnesota.
“There can be significant psychological comfort in having your pet close by, which can help both initiate and maintain sleep,” Kolla said.
“However, if patients are reporting that movement or other activities of the pet are disruptive to their sleep we then counsel them to try to look at alternate arrangements for the pet at night and see if that helps with their sleep,” he added.

A setup for success
Successfully co-sleeping with your pet has a lot to do with how deeply both you and your pet sleep, says clinical psychologist and sleep specialist Michael Breus, the author of “Good Night: The Sleep Doctor’s 4-Week Program to Better Sleep and Better Health.”
“Dogs are usually good for an entire night but cats can be very nocturnal,” Breus said, adding that another factor is how “much you both move, as movement by the animal can wake the human and vice versa.”
Pets, like people, can also snore and disrupt sleep, so be sure to take that into account, Breus said. Small dogs and cats often like to snuggle under the covers with their people, but that can raise your body temperature and disrupt your sleep. (The best sleeping temperature is a bit chilly, at 65 degrees Fahrenheit or 18.3 degrees Celsius.)
If you’re thinking of bringing your fur baby to bed, Breus suggested you give it a try for only a couple of nights, so that you don’t condition your pet to expect it before you decide if it’s good for you.
