Humans like to give ice cubes to dogs because they figure, hey, it'll be fun. But, they have no idea the war dogs have been waging against this way-too-slippery substance for centuries (probably). There's a battle going on between dogs and ice cubes, and the dogs are determined to win! Hint: They probably won't.
Dogs have finally discovered where the ice cubes have been hiding. This. Means. War.
