So Freyja used to be a very eager puppy about meal time. I feed her 2/3 of a cup of Blue Buffalo puppy food twice a day and she would be so excited as soon as I set down her food bowl. Something has all of a sudden changed! She really has no interest in her puppy food and wont even touch her food bowl until it has been sitting there for a few hours. We have tried to sprinkle cheese on top to get her interested but then she only eats the cheese. Should I attempt to try another puppy food? Stop giving her little treats like cheese to entice her to eat her own food?
