The Drs. Foster and Smith Catalog has such a huge variety of dog beds in it with a numerous types of cushions and covers that it is hard to choose. They have a website as well, but I would suggest getting their catalog. Petsmart seems to be a little pricey and if you are lucky and careful in choosing you can find some very nice ones at Target and K-Mart in thier Pet sections. You'd want to make sure you can get one with a removable cover. It is rare to find one where the innards are washable, but I do know that some in L.L. Bean have a cover on the stuffing part is liquid repelling.
