Kumfy Tailz Kumfy Pax 2X7, fits size X-Small

Description

Kumfy Tailz uses the same concept and technology as human sports- and physical-therapy warming/cooling gel paks. The Kumfy Pax is a puncture-resistant nylon/pvc enclosure filled with special UltraGel, which can be warmed in your microwave, or cooled in your freezer. After an hour in the freezer or less than a minute in the microwave, the Kumfy Pax is inserted into the special Kumfy Pouch, where it keeps your dog warm or cool for up to an hour.
