My little Chihuahua, Daisy, is my alarm clock. I never get to sleep beyond 7:00 AM! She crawls out from under the covers and starts to march up and down the length of my body and if I try to ignore her and sleep she starts barking and growling until I finally have to give in, get up, let her off the bed onto the seat on my walker and take her to the doggie door and let her out. She's very vocal and definitely lets me know when she wants attention!!!
