I also feed Innova,( the senior formula) and my dogs have been doing very well on it. They eat the dry kibble, and I dont add canned, as they are very happy with the dry.

You can get more information on this food at http://www.naturapet.com . Its made of human grade ingredients, with meats as the first ingredients rather than corn or bone meal or something. They eat less of it than cheaper food, so although it costs more to buy , it lasts longer, also they do have smaller stools because they can absorb more of it.

I have tried many other brands with them, and have been very pleased with the Innova.
