Abstract: K9 Therm-a-pack is designed to apply ice or heat packs to a dog's hip or lower back area with out the owner having to bold it in place. Comprised of water proof or resistant material to keep the dogs skin dry, two pockets hold the ice/heat pack in place while three adjustable straps secure the pack in place on the dog. Two straps go around the dog's hind legs and one around the waist attaching with a plastic clasp that allows the straps to be adjusted in length.
