Dave, there was no tofu or patuli oil involved that I know of. The real problem was that all of the eating happened about 6 to 8 hours before I returned from being gone for a week so I didn't even know what type of food he MIGHT have eaten. Apparently, there was quite the feast made (salmon, potatoes, beef, and side dishes). I KNOW that he ate a potato but have no idea what else. Apparently though, it was a lot of fatty foods. I'm guessing left over steak fat and lots of butter were the main culprits but it is possible that some seasoning/spices made things a lot worse?

I too had NO idea that something as simple as feeding them rich human food could cause this issue. In 15 years of dog ownership, I've seen my share of "mud pies" and puking of grass balls and odd items but I've never seen anything like the violent dry heaving. It would subside for 2 or 3 hours and then go 10 minutes straight like he was almost choking. That went on for days.

Onward and upward!
