Round donut bed, It's a bed that we have had for a long time. It is a great thick bed for the older dogs. Filled with top quality polyester filling it is completely machine washable and dry-able without removing a cover or doing anything special. The 2 smaller sizes are made in one piece so that the little dogs do not get "stuck" in the bed and the larger sizes are made in 2 pieces to make washing easier. These are made in cotton, anti-pill fleece and denim.
