Whether or not a dog is allowed in the bedroom is a highly individualized decision: Some pet owners are eager to cuddle up to their pup at night, while others banish Fido from their sleeping quarters.

Now, new research attempts to shed some light on whether letting a dog sleep the bedroom helps or hurts a person's efforts to get a good night's sleep.

A small study from the Mayo Clinic finds that sleeping in the same room with your pet does not appear to affect quality of sleep. In fact, it may actually lead to a more restful night. However, that benefit does not extend to people who actually shared their bed with their pet, which the research found may negatively affect sleep quality.

"Most people assume having pets in the bedroom is a disruption," study author Lois Krahn, M.D., a sleep medicine specialist at the Center for Sleep Medicine on Mayo Clinic's Arizona campus, said in a statement.
