Given the infamous corgi appetite, I thought it would be fun to find out what our normally omnivorous corgis will refuse to eat. (It was nearly a year before I found out that most dogs don't eat vegetables!) In our 2+ years with him, Edison has only ever turned down lemon slices, wasabi peas and stuff with A1 sauce on it- he'll actually reject steak if it is thus contaminated.
So... what does your corgi NOT eat?
