Shedd crate pads are designed for pups that are rough on their crate beds. These are constructed with a scratch, chew and abrasion resistant material and come with a unique tie down system. This allows you to attach the crate pad directly to your metal crate, keeping your dog from flipping the pad over inside the kennel, and preventing the majority of damage that dogs do to their crate pads. A premium water-resistant liner comes included. Shedd crate and kennel pads come with a Certi-Pur US certified orthopedic foam that offers your pup a supportive and safe resting place. The cover and liner are machine washable and stain, odor and mildew resistant. You and your pup will fall in love with the quality, exceptional American workmanship, and ultimate support with a crate pad that is designed for durability.
