Nearly two thirds of all U.S. households have at least one pet. An overwhelming number of those furry friends are considered family members or companions, so it’s no surprise many of them find their way into an owner’s bed at night. But should pets sleep with you? The research varies, and studies show both risks and benefits to sleeping with your pet. Consider the pros and cons of sharing your bed before you snuggle up with your pet. Benefits of Sleeping With Pets Pet ownership has many well documented benefits for humans and animals.

In addition to health risks, some veterinarians suggest it might also be a bad idea to have your dog sleeping in bed with you because of behavior issues. Aggression and housebreaking can be a problem with some puppies allowed to sleep in bed with an owner. If you really want to sleep with your dog, make sure to wait until after your dog is completely housebroken and behaviorally mature. Minimizing Risks and Sleep Disturbances If you allow your dog in bed with you, take your dog—or any other co-sleeping pet—for regular veterinary visits and keep all vaccinations up to date. Also, be sure to use medication to prevent fleas and ticks, as well as treat illnesses. If your pet is disturbing you, consider a different arrangement.
