Molly Mutt Large Dog Duvet Cover — Refillable Design — for Large Breeds — Great Dane, Mastiff, Bernese Mountain Dog

Molly Mutt's iconic duvet cover solves the dog bed sustainability problem: instead of buying a new dog bed when the fill flattens, owners stuff the cover with their own old blankets, pillows, or Molly Mutt's recycled PET fiber fill, extending product life indefinitely and diverting textile waste from landfills. Printed in bold, design-forward patterns on 100% cotton twill, the duvet cover elevates the aesthetics of large dog homes with an oversized 52×36 inch base suitable for Great Danes, Mastiffs, and Irish Wolfhounds stretched full length. The cotton shell is machine washable and the double zipper closure stays closed even during the most aggressive nesting behaviors. Fill weight can be customized to create either a thin mat or a plush cloud based on breed preference.
