Brilliant, why don't I think of these things. Molly Mutts has come up with a brilliant idea for a doggy bed. They are removable and washable covers that fit over an interior stuff sack that you fill with old clothes and rags etc..!!! Voila - brilliant, so smart. Not only are the clothes much more comfier than the traditional dog bed fill, you can wash all the clothes inside and also easily change them out if there is an accident.......love this idea.
