Our chew proof beds (also known as the Chew Proof Armored beds) come in five different types. All beds are sized to fit standard wire crates and all beds feature the same aluminum frame; the only difference is in the center material: Chew Proof Armored Rip-Stop Elevated Dog Bed  Bed sling is made from rip-stop ballistic fabric Does not contain padding Has a waterproof coating on the underside to help catch spills Cannot be used without legs Material is breathable to keep dog cool in the summer Good for dogs that chew heavily and those that like to scratch at their bedding Works in any environment Chew Proof Armored Dog Crate Pad Bed sling is made from rip-stop ballistic fabric Contains about 1.5" thick polyester fiberfill stuffing for comfort Has a water-repellant coating to help protect against moisture, but not 100% waterproof Does not come with legs, but legs can be added to elevate it if desired Padding provides insulation against cold Good for dogs that chew heavily and those that like to scratch at their bedding Works best in wire crates and indoors Chew Proof Armored Padded Elevated Dog Crate Bed Bed sling is made from rip-stop ballistic fabric Contains about 1.5" thick polyester fiberfill stuffing for comfort Has a water-repellant coating to help protect against moisture, but not 100% waterproof Comes with legs, but can be used without them if desired Padding provides insulation against cold Good for dogs that chew heavily and those that like to scratch at their bedding Works best in wire crates and indoors Chew Proof Armored Vinyl Elevated Dog Bed Bed sling is made from heavy-duty, double-coated vinyl Does not contain padding Material is fully waterproof Cannot be used without legs Helps keep dog cool, but is not as breathable as the rip-stop version Good for dogs that both chew and dig heavily.

Or, if you need a cooling bed for a dog that likes to chew but doesn't really dig at their beds, the mesh is a great choice. If you need something to sit on the floor of the crate that won't get chewed up, then the Chew Proof Armored Dog Crate Pad is the bed for you.
