What has the blood work shown? Infection, elevated lipase etc? At this point I would be opting for exploratory surgery to rule out foreign body, a string or thread cutting off intestinal blood supply, intestinal torsion etc.
reTThey didn't check his blood or for pancreatitis. They haven't done blood work, I think I'm going to insist on that this time, going to take him back tonight.They did send home with prescription food but he wouldn't eat any of that. Then when they called to check on him they were surprised he wasn't eating and suggested I try the baby food meats etc as I mentioned. Thanks for your advice, I do wonder if it is something with his diet. I have even muzzled him for yard time to be sure he's not ingesting something I'm not aware of. Very stressful!
