Love your suggestions! What you have described with your own dogs, makes perfect sense. I believe my dog is trying to find a comfortable place to lay and definitely something cooler than carpeting! When he is outside he does the same thing - digs a hole to lay in, where inside he cannot get the same result on the carpeting. The corn idea sounds interesting if he would get into a tub. I had thought about just covering a piece of plywood with ceramic tile just to give him something cooler to lay on. The shelter might be a better option. I am willing to try anything at this point so we can all get a good night\'s rest!
