I don't know anyone who has a dog that's well-trained enough to come into the bedroom and NOT immediately jump on the bed . . . but apparently those people are out there. And they're sleeping GREAT.
According to a new study by the Mayo Clinic in Arizona, people who let their dogs in their room at night sleep BETTER . . . because it gives them comfort and makes them feel secure.
But . . . if you let your dog onto your bed, then you wind up sleeping worse.
