On a recent trip to Orlando to visit my sis, she and I went to JoAnns and bought a big piece of foam and 3 yards of polar fleece. Back at her house, I made her Doberman, Kiera, a new extra large bed and covered it first with muslin (velcro closures) then the polar fleece (brown with cream paw prints all over pattern) with a 36 inch zipper for easy removal. Kiera LOVES her new bed!!
