Designed to keep pets cool! Just pop the Ice Pod in your freezer and leave it for three or four hours. Then place the Ice Pod in your dog's crate either on, or under, his mat and watch him chill out! The round tapered shape of the Ice Pod is intentionally designed so that animals can lie across it comfortably. 8.5" in diameter and 1.5" high. Refreezable and reusable.
