I tried something that worked for pilling the rooster... coat the pill in peanut butter and then dust it with cornmeal so it's not sticky. He tasted a little then ate the whole thing. Hoping it works tonight too.
His last owner called today and said the wormer they have him in is cheap crap that doesn't treat barely any worms. It's panacur. I asked him for something that would treat gapeworm also. She said she got him from Iowa, and that she didn't NEED to sell him. I said I didn't need to buy him, but he's here now. Her attitude was in between being nicer and yet still, not her fault.
On a positive note, he hasn't been breathing out of his mouth really at all today. He hasn't been coughing or yawning/stretching as much either.
Here's a couple pictures today. To me, he just looks tired.
