Ah, we posted at the same time. So she's a gulper then?? That CAN cause to throwing up. I suggest feeding smaller portions throughout the day. If she only gets 1 cup a day, feed two meals of 1/2 cup twice a day, see how that works. Otherwise try other methods... there is osmething called a Buster Cube, http://www.bustercube.com/ you can use to have your dog have to work for the kibble, and only a little falls out at a time, so she won't be gulping it.
