Daisy is constantly stratching due to food and environment allergies, so after reading many threads I thought I should change her Royal Canin food to the Natural Balance. The pet store only carried the potato and duck small bites. I am mixing the two foods so that she doesn't get sick. Well she picks out all the Natural Balance and throws it on the floor and only eats Royal Canin. What flavour does your yorkie prefer? Any suggestions on how to stop her picky eating habits.
