Thanks for all the comments! Right now my dogs have pillows that they lay on outside. And they have a quilt they lay on in the house,yes, spoiled rotten! lol! And there is always the bed with us!But they also like it outside on some of the coldest days, I think they are nuts!
I may just stick with the pillows and make a new cover for the pillows and add a layer of the egg carton foam to them. I do know they like the egg carton foam as I made a big pillow for the back of our car for when we go on vacation, I said they were spoiled, they go where we go! Thanks again.
