Amy, this is what I plan on doing for Duke and you might want to do the same. It sounds like what Sandra was talking about. Here's the link to it. They are very nice hand painted wooden urns. Pretty reasonable in price, as well. And if it helps, I'm sitting here crying as well. Those poems and your story made me sad. I know Duke is my special dog and I cherish every day with him.
