We have a snow and ice eater here. I think Scout cannot go outside without having one or the other in his mouth. He thinks they are a wonderful treat and just picks up clumps of snow everywhere and either carries them for a while or just plain eats them. Tonight on one of our trips outside he found a real hard chunk of ice and carried it around the yard. Then I had him drop it so we could go inside. On the next trip out he remembered where he dropped it in a yard of snow and proceded to lie down and gnaw on it again. He is just wierd.
