I love this food. I have tried other cheaper brands and also other high end brands. The large chunks are suitable for your rottie, they are moist but not enough to be squidgy, my rotties coat is shiny and he looks healthy. It's also great on a personal level as my rottie is unfortunately picky when it comes to food. But this he loves!
our dog likes these granules so much - a little surprising to me. She always goes to their storage place so that I know that she wants them, and wants them now. We do have to work a lot and she doesn't get as much exercise as she should..but I think she even lost weight with these!
