My Mom had a dog that the groomer thought was mostly Lhasa Apso called Missy. Missy loved to sleep under the kitchen table when anyone was visiting. Her whole life if you accidentally stretched your legs out and bumper her with your foot she woke up growling and acting like she would like to eat your foot. She never bit or anything but it always startled me (and just about everybody else). It was just one of her things. I guess she just woke up cranky, and took the whole getting disturbed thing personally. Hope this helps. Charlie is cute.
