K9 Ballistics Tough Crate Pad CHEW PROOF RATING: 4/5; this pad is intended for LIGHT or MODERATE chewers and will resist about 90% of chewing dogs. For an anxious or persistent chewer, we strongly recommend our Ballistic Chew Proof Cot Super durable Ripstop Ballistic cover resists chewing, scratching, water, hair, dirt, and odors, and can be easily wiped down or machine-washed in cold water Stuffed with polyester fill to a 1.5 inch thickness for comfort and stitched shut, this pad does not contain any zippers or Velcro closures Designed for 42" x 28" crates but flexible enough to be folded over and fitted into crates of smaller dimensions Covered by our 90-Day Chew Proof Warranty; if your dog damages the pad within the first 90 days, we'll replace the pad once free of charge
