There's a dog that sleeps with me everynight and insists on sleeping under the covers. It messes the bed up and is somewhat irratating but I can't stay awake all night to make sure she doesn't go under. I'm somewhat clausterphobic myself so it freaks me out wondering if she's getting air under their on her side. She's a rescue dog. Could this mean that she is used to sleeping in a crate at night? Is this what perhaps she'd prefer instead of the comforts of my bed? Its not that she's cold or anything, no matter how hot or cold, she still insists on sleeping under the covers and hidden. Any suggestions as to why? I'm afraid I might sit on her some mornings when I'm getting ready for work, she's a little thing so sometimes I'm not sure if she's back in bed or walking the halls.
