This bed was specially designed by Cesar to surround puppies with the same sense of security as their mother. The bed's sleep surface is made of Micro Velvet which is a polyester fabric that feels just like velvet. Includes a center bolster, filled walls and a layer of comfort fill for cozy softness. Plus, we've added a non-skid bottom to help keep your bed in place.Cesar's tip: "Communicate your intention simply and clearly."
