Gracie is always knocked out cold by 8:30 - 9:00, she wont move a muscle. Unless you ask her if she wants to go outside. You can come right into my house and she wont even lift and ear because of the noise. Lol. She is a great protection dog. When I go to bed I take her out one last time, so brush my teeth and all of that good stuff. She will then start pacing, she goes from the front door to the back door, then she sticks her head in our room to make sure were okay. Then she goes to bed, and doesn't like getting up before 9:00 am. She's such a silly girl.
