Our miniature long haired chocolate dapple Dachshund has a habit of sratching usually about 2-4 miniutes on the surface where he is about to sleep for the night.He sleeps in bed with me,and he scratches on the sheets.Our female 'Red-Piebald does not turn in circles or scratch at all.She lays down instantly.By scolding him will this cause more of a nervous reaction to this?This male dog loves to dig holes in the beach sand.He digs about 16 inches deep.His father is a Canadian champion and I wonder if this habit is in fact a trait that this strain of dogs have inherited?
