wah that's a lot of different foods. Thanks everyone, you definately gave me a lot of options to check into. I also checked out the boxer link and that gave me a good idea what to look for while I'm checking into the different ones listed. I've heard of a few of them:

Chicken Soup
Canidae
Solid Gold
Nutro Ultra

But there not considered "main stream" so most people I asked didn't seem to know much about them, which is why I hesitated since I wasn't sure if they were good or bad. I'll take another look now that I have an idea what to look for.

On another note but similiar topic, I'm also trying to find a good weight control food. One of my dogs is an ~ 8 year old aussie/pyraness mix that has weight problems. He's currently on science diet R/D and has been since we got him about 3 year ago, which I'm not a big fan of. The problem is every time I try to switch him to a different weight control he gains weight even when I restrict his food. He gets walked daily and plays with the other dogs, but because he has arthritis in his back legs he can only do so much with regards to exercise.
