What you're looking at are  the stomach contents of a 3-year-old, 120-lb. Great Dane from Portland, Oregon who kept throwing up. The Dane's owner was aware that he would occasionally go after socks, but the extent of the problem was not apparent until the dog got sick and got taken in to DoveLewis Emergency Animal Hospital, where they suspected he had an intestinal blockage.
