Pumpkin had his barium test done today and all went well. They put the barium on a banana and he ate it. On the flip side, we still don't know what's wrong.
His test was to see if he had a diaphragmatic hernia. Although the test show his stomach and intestines are in the right place, they think he may still have one and that his liver is poking through.
He didn't have a diaphragmatic hernia. It ended up being a collapsed lung. But we got him through it and he is perfectly healthy now and his lung has re-inflated.
