These are our trickiest customers & it's important to know that NOTHING is indestructible when it comes to dogs. We've worked hard to develop clever preventative measures... hidden zippers, stitching our tags flat & some 'tougher' products to add to our range but puppies are generally better suited to a cardboard box & towels (our cardboard Puppy Cubby is an ideal option as it also assists in training puppies to use a kennel as they get older). Adult chewers should never be left unsupervised with their beds.
