I don't know if everyone saw the other thread, so I will explain again.
River maintains a healthy weight on the grain-inclusive varieties of farmina (and on the lamb and millet Canine Caviar, but *I* like Farmina as a company better). On every single grain-free kibble I have attempted to feed her - Orijen, the Farmina grain free line, Instinct, Earthborn Holistic, Solid Gold (I got desperate), etc. - she dropped weight rapidly, no matter how much I fed her or how many meals I broke it into. I intially balked at the idea of putting her on a grain inclusive kibble... but I got desperate enough to try it, and she does much better on kibble with grains than without. It doesn't make any sense, and like I said, it flies in the face of everything I thought I knew, but that is how she is. She is parasite-free and her thyroid and bloodwork were fine, but she was so thin at one point that I was seriously worried about her, the vet was worried about, and I was constantly accused of trying to starve her to death. It was horrible, and I do not under any circumstances want to go back to that.
Hence my concern about her potentially dropping weight on raw. If she can't maintain on a grain-free, moderate carb kibble, will she be able to maintain on a grain-free, very low carb raw diet? I just don't know.
If nothing else, I guess I could try a modified Volhard method and give her veggies/cereal/egg/goats milk for one meal and the HT grinds at the other, since it may not be a good idea to mix them. But then there is a voice in the back of my mind going "grains are BAD! you KNOW that. DON'T feed her grains. She doesn't need them! You are going to give her *insert disease here* if you feed those!" and on the other side of the table is a voice that says "Well your logic almost killed her, didn't it? Shows how much you know. You were WRONG and you made her SICK somehow and apparently SHE does NEED grains in her diet. You can think all you like but her condition doesn't lie." And I am going back and forth between being one or the other. And I am probably going to think myself into a corner and just keep feeding her kibble, wondering why I can feed a cat, but not a dog, when dog nutrition is supposed to be easier. Right.
