I love Innova, especially with large breed dogs. It has the supplements that can help prevent joint problems that are needed with large breed dogs. The one objection I have is that is is very rich and if you have a dog with digestive problems, it can be a little to rich for them.

I had Leo on it for a short while, but he has a sensitive stomach and it gave him the runs. I now have him on Eagle Pack holistic. My sister has GSD's and swears by it. She had a dog with allergies and hip dysplasia and and swears it prolonged his life.
