I've been very happy, as have my pups, with our wool filled Molly Mutt dog bed. Having a waterproof liner and washable cover was paramount for us. Our two Italian Greyhounds rarely smell or need bathing but they do need their bedding washed just like we do. Our last dog bed was not washable. It began to take on odors so we knew it was time for a change. We ourselves sleep on a wool and latex mattress and felt wool was the best option for our girls as well. I also spin sheep's wool on a spinning wheel and find the odor of good clean wool quite lovely. It's fresh, clean and maintains its loft quite well. The Molly Mutt bed ticks all the boxes and is worth the price paid. Our girls seem to agree! I would definitely recommend Molly Mutt products and would buy again. Bonus is that they are a local to me company!
