Our Kerry turned his nose up at all other beds. When he stayed at the boarding kennel, he preferred the concre floor. The Casper is the ONLY bed he’s ever used free choice. Unlike foam chip stuffed beds, he doesn’t scratch/dig at it or circle to find a comfie position- this has decreased wear on the fabric. The cover is secure, yet comes off easily for washing. Best dog bed ever. While our dog could technically fit into a small, we upped to the medium size so he could stretch out.
