Just curious if anyone has any idea on where to find some sort of soft bed or mat for the Shepherd puppy that does chew. Right now I am using blankets which one had stuffing in it and it got chewed up. I am trying to prevent any calluses forming from lying on hard plastic. Any ideas would be great. I was thinking of possibly a rubber mat to make it a little softer, which we use in K9 vehicles but am not really sure if it will prevent calluses.
