It is a calming dog bed for senior dogs and dogs with arthritis who are anxious. The non-slip bottom can fix the position of dog beds. It brings more security to your dog. There is no need to worry about the dog wetting the extra large dog bed because there is a waterproof layer under the plush surface of the dog couch, which can prevent liquid leakage and fully protect the foam.
