COOLDANNA™ Cooling Doggie Mats are designed to provide instant cooling relief in hot environments for all dogs. Simply soak the mat in water and allow your dog to sleep on it. The super absorbent crystals in the interior of the mat will absorb over 1,000 times their own weight in water and provide cooling relief for days. This attractive product is made from a soft, comfortable fabric that enhances evaporation and cooling. These are a great way to 'air condition' your dog and keep him/her ultracool. Size: Medium 20" x 24"
