I feed Acana Grasslands (lamb formula). Its about 35 dollars for a 17 pound bag I believe. It's a 5 star rating.

Always remember, the higher quality, the LESS you have to feed. In the end, it's isn't as expensive as you might think it is because it lasts longer. I would also recommend california natural, I had my dogs on it for awhile but Sam does much better on grain free food. I think that is a 4 star food.

For example, Springen was on Royal Canin Boxer Formula. (CRAPPY food, my brother insisted he thought it was good) They recommend about 4 cups a day for his weight. He just switched him to grain free Blue Wilderness, and they recommend about 2.5-3 cups a day. Big difference!
