Low ash and high protein are almost opposites. I would go with high protein no grain and add your Cranberry Comfort and see how it goes. Does Cranberry Comfort have vit C in it? If the pH strips show a pH above 7, I would think about adding a little vit C, if the CC doesn’t have it. If it does, wait until you have had her on it for a day or 2 then retest. If you’ve already had her on the CC for a couple days and the test strip still shows high, then I would go ahead and start adding the vit C. Adding it won’t hurt, as long as you don’t go crazy, so you really can just add it anyways. For myself, I would just want to know how the different elements of my dogs diet were affecting her.
