Do your pets sleep in bed with you? Mine do. My bedroom's like a Jack London novel. But there's a new study that claims that having your pets sleep in bed with you may not be the best thing for a good night's sleep. In fact, a study by the Center for Sleep Medicine at the Mayo Clinic in Arizona suggests Dolly and Ellie may be demonstrating behaviors that actually keep me awake at night. And I'll admit . . . they snore, they dream and whimper, they growl if someone tries to move them and, at times, they can be a little gassy. But is this really affecting my sleep patterns?
