A few weeks ago I got her Victor Nutra Pro for Active Dogs and Puppies and it seemed like she was eating it, but not very much. She is now really skinny, and I've been giving it to her 4 times a day and leaving it out for 20 minutes then taking it back inside. Two days has passed and she has not had a single bite and will refuse to eat it. A few days ago I gave her some puppy food with tons of fillers to see if she would eat that, and she scarfed it all down, but with this food, nope. The food she won't eat is extremely high on protein, which she needs. Please help me, what do I do? Do I switch the food? I'm thinking about Blue Buffalo.
