He does have a tendency to eat underwear.

Uhm, you might want to take action to prevent that. Intestinal blockage can be an extremely serious as well as deadly matter:

If the blockage interferes with the flow of blood to the bowel, intestinal strangulation will occur, and the bowel will start to rot within a few hours. Abdominal x-rays are needed to properly diagnose the cause of distress and locate the blockage. Surgical removal of the blockage is required immediately, and the rotting bowel must be resected to the living bowel.

It's a lot simpler (and cheaper) to pick up underwear.

You don't understand...we never SEE him eat them. Believe me, after losing over a dozen pair, nearly all my wife's, we are, ah-hem, anal about picking up and putting away underwear.

Best we can figure is the the dog gets them out of the hamper (which is a good foot and a half taller than he is) and somehow manages to take ONLY the underwear.

We have had many discussion with our vet about it. Rufus seems to be built in such a manner that the underwear gets stuck in his stomach where it gets partially digested and eventually exits the way it came it. Totally gross. Since we don't see him do it, we don't know he has done it until we find the evidence after the fact.
