Just my thoughts.

Ten days of Metro may be okay for two episodes of vomiting, but it seems extreme. The xray was a good idea, but with just two piles of vomit..not something I'd rush into. Xrays do help rule out obstruction, but barium is needed too for the best look. If there is a pattern of throwing up, then it is time for bloodwork. However, I wouldn't yet call this a pattern unless it happens again.

That said, he had demodex and you said he gets a bit lethargic after taking his heartworm and flea drugs. That's not normal. So IMO blood should be done even if he wasn't vomiting. The drugs may also need to be changed. I'd be doing a blood panel with CBC just to see what is going on in there if one hasn't been done in the last few months.

No treats or edible chews right now. I'd do one food and water only for a few weeks. Adding extras in will just complicate the process trying to figure out what is causing the problem. It's normal to throw up after eating grass, but a lot of dogs eat it in the first place because they are nauseated. Depnds on the dog.

The foreign object thing - you just have to go with your comfort level.
