I seen on The Dog Whisperer once that Cesar said that you have to make the dog get hungry. A lady was having the same problem but with an older dog who wouldnt eat anything but things she had to cook. Then it got to the point where all he was eatting was these certain treats that were very expensive. He told her that she needed to get him out and excercise him and that will make him hungry and make him want to eat. And she did and of course the dog started having an appetite and eatting DOG food. So maybe try a lil bit of walking. Who knows.
But I also have to agree with everyone else, that maybe the Nutrical was filling her up to where she didnt want anything else to eat.
