I was tired of replacing our dog beds every six months or so because they became threadbae or tore at the seams. I decided to get two new ones and cover them with a duvet from Molly Mutt. The duvets I received are very well made, very sturdy, and make laundering easy since they slide right off and into the washer. They are thick enough that the bed underneath stays clean. We've had one of the duvets for several months now and it still looks brand new. I'll be purchasing these again (if the ones I have ever wear out, that is.) I highly recommend these as an easy solution to having clean dog beds.
