My poodle hid his Oreos in my sleeping bag until one night. I went to slip my feet in and felt something cold and wet. Sure enough, he'd hid his treat in there. When I screamed, he came up looked at me tilted his his head and proceeded to pull out the cookie. I slept in a northfacing bedroom (in the Midwest) so in the cold late 70's winters I'd sleep in my sleeping blanket (flannel lining) with quilts on top. My family treated the dog as well as me....he even had to have his tonsils out to cure his winter hacky cough.
