The Doice Vita Thermabed with memory foam has all the great features of the stand Therabed. But we added special foam that evenly distribute your large dog's weight. It's an ideal solution for relief of your dog's sore joints and muscles. We wrapped the pet bed in a removable, machine washable microsuede cover. The cover is scratch, water and stain resistant.
