Well... I ended up using the samples of the Diamond Products and as I posted on another thread, she's doing GREAT on it. Much better then she did on Nutro. She has more energy (MUCH more energy) and her fur is so shiny. The only problem I've had is finding it. I've only seen it at one store (a family feed store) and not in any of the commercial places. According to the rep from Diamond Products, they're VERY selective about who they allow sell their product.
