Is letting the dog sleep in your bed really a good idea?
But is sleeping with your dog a good idea? Wouldn't it be detrimental to your sleep? Not really, according to a recent study. Researchers at the Mayo Clinic in Phoenix studied 40 adult dogs who slept in bed with their owners. The humans generally slept well and had no sleep disorders.
The dogs wore a piece of equipment called a Fitbark, an activity tracker attached to the collar to record whether the animal is resting and sleeping or active and playing. The people wore the Actiwatch 2, an activity monitor that records movement and whether sleep is deep or not. The two monitors were set up to sample movement every minute, and people also kept a sleep diary.
During the seven-day test, the researchers found that with a dog in the room, both humans and dogs slept reasonably well. The humans had an average sleep efficiency, or the percentage of time they spent sleeping while in bed, of 81%, while the dogs had an efficiency of 85%. In general, levels above 80% are considered satisfactory. People slept slightly better when the dog was not in bed; dogs slept just as well in bed or elsewhere in the room.
The key is to create a similar sleeping experience for the animal. Dogs may be attracted to humans' beds, especially if they are elevated, "because they are comfortable and in a strategically good position.
