Today I received a very cool doggy bed cover, no not for dog beds but for my bed (which the dogs think is theirs!) Below you can see Mukki and Quinn testing it out! It looks a little messy because the guys offered to test it before I could straighten it out.
I got it on Woot for $19, so you might need to search around to find a bargain, but here is the web site with a movie. I have a really thick 18" mattress and it fits well and even covers pillows! This is a link to their web site: pawsOFF Bed Cover
