961 Hi Sue,
I think all “puppy food” formulas are a marketing scam or a sign of a poorly balanced brand to begin with. My ol’bulldog Rhoda went totally dysplastic from the “large breed” formula scam. In Orijen’s case they use a lot of deceptive marketing, so I dont trust that company – I use their label as an example to the trainer’s certification class (tons of ingredient splitting and other tactics that are designed to make a better label and not a better food). So I always just use something that is “balanced for all life stages” and an honest label. If you rotate for health reasons that is one thing. But, coming from someone who has had hundreds of dogs in his care I can assure you that giving into a picky dog is never a good idea. They will never starve themselves to death. So if you find something that you think will be healthy for her, just follow the rules of picking it up when she turns her back to it and dont offer it again until next meal. I promise promise promise you she will eventually eat whatever you give her. They can go days without eating if they want to. It is in their evolution to do so. From there you can make gradual rotate to whatever you want and do the same, since many people do like to switch it up every once in a while. Rottie’s usually hold their weight well, so you may be feeding her too much. You will surprised how little they can eat. Milo, who is 95ish pounds eats 3 cups total/day on lifes abundance (482 kcal/cup).
