The Nylon Daddy is made of high quality nylon that is easily cleaned.... I mean easy. This L shaped head rest bed is perfect for that dog that has a hard time learning to potty train. The Nylon Daddy is of course great for a dog that is potty trained, but the ease of cleaning is handy when your dog just can't get it right with the potty training. I would never buy this bed. Any dog that has an accident on its bed more than a handful of times, is a dog that is a terrorist that has many more problems.... barks all the time for no reason....try's to bite everyone. Just a pain in the ass dog. Some people love pains in the asses. Ladies, look how many of you are still with your man....
