This one of a kind therapeutic pet bed provides both cooling relief to an over-heated pet and soothing warmth to a chilled or arthritic pet. The time-tested gel packs can be cooled in the freezer or warmed in the microwave. Each pet bed is constructed using a tough 1000 denier Cordura Nylon outer fabric, and the inside is made using a 10-ounce fiberfill batting. Each of the corners and pockets is protected using a 40-ounce truck tarp material, creating the ultimate chew and scratch resistant pet bed. Its pillow side provides relaxing multi-layered comfort.
