Charlie did have a blockage, and Uncle Craig was able to remove it surgically.
There was a pretty big piece of cob in his stomach, which was not going to make its way out on its own.
Tim is on his way home now, and Charlie w/ be down & out for 2 weeks.
Craig suggested having him wear the collar backwards, which will still prevent tampering w/ the wound, but won't be such a danger to all of us. We're going to give it a try!
Thanks for you concern, and most of all, for your prayers.
