The intestinal tract slows down. It is rare that we need to do surgery to get something out of the colon but we sometimes do. Something more aggressive needs to be tried even it is to gas her down and if it is low enough in the colon try and manually remove it by going in thru the rectum (this of course is for your vet to do). If it is too high then I would go in surgically so that you can get a quicker resolution. Good Luck and don't waste any time; this can get worse instead of better. Dr. Sue [Posted in FML issue 4611]
