HI Christa,
I'm having the same thing with Annie, although it's not an everyday thing. Sometimes she throws up and it's whole food, so I shrug it off as she ate too fast, but other times it's already digested food. She is due for her yearly exam as well, so I guess I will ask the DR when I go. She also has been eating the same food since she was a baby, so I don't know what could be causing her problem. My mom gave me some samples of some different food and I'm trying that for a few days, or at least untilit runs out and if she doesn't throw it up, I guess I will have to buy that food, unless the DR says otherwise.
