Julie and Jimmy Johnson are no strangers to dogs. They have three of their own that regularly sleep in the bed with them in their home in southeast Tennessee. But recently, the couple woke up to find a large tan dog sandwiched between them that was not one of their own. "You could see light coming into our curtains in our bedroom and I feel my husband not just roll over, but kind of startled, like almost a jump roll over and it woke me up," Julie said. "And in a quiet but stern voice, he said, 'Julie, whose dog is this?' " It didn't take much time after that to realize that the strange dog was not a threat, but instead a cuddle bug and maybe a bit of a bed hog as it pushed the Johnsons to both sides of their king bed.
