I searched and read and ask questions for a couple weeks before I finally chose Nature's Variety chicken and brown rice for Gertie and Arrow. All their varieties are 26% protein and I liked that. I didn't want Gertie or our St. Bernard on too high protein. Gertie has been eating 1/2 and 1/2 her old food all week and she already isn't pooping so much. With her old food, she went about 4 or 5 times after each feeding. She's also nice and firm, and doesn't poop so much at each trip outside. With her old food, she was firm and then she'd be less than firm, for no reason, and she would leave a HUGE pile. Sometimes I'd think, Holy Cow, where is it ALL coming from?!? So far, I'm very happy with it for Gertie. Arrow, unfortunently, must be allergic to something in it, so he's back on his old food. I'm going to try to switch him to something better, his old food only has 2 stars. But for now he's fine on it. The 5 star food didn't agree with him at all.
