Additional Details ------------------------------ Product description: Dogs love ice cream, and here's a safe and fun way to let them have it! Cool Pup Cooling Toys can be filled with water and frozen, to give dogs an icy-cool way to enjoy traditional summertime goodies! Instructions for cooling: Fill with water by submerging in water, or hold under the faucet. Squeeze the toy to release air bubbles and allow water to fill the inner cavity. Place the toy in the freezer with holes facing up so water does not leak out. Keep the toy in the freezer for about two hours until the water is frozen. Remove the toy from the freezer and give it to the dog to play with outdoors or on a water-resistant surface. For a maximum cooling effect, let dogs play with this toy on a cool surface. Do not allow the pet to play with the toy if it becomes damaged. Supervision is advised.
