I had a similar problem too, when I switched brands on my dog. The only time he would eat it was when I would toss it on the ground. I got scared that he would get used to it, so I stopped doing it, so he stopped eating. I figured that he probably didn't like the food, so I switched brands again, and now he's back to normal.
Thank good, because feeding him 3 kibbles at a time was very time consuming!
