What kind of food do you feed your dog?

Well I just recently was given a puppy(10 weeks old/I think its a boxer mix).
I have been doing research on what food to get and I came across a website that had a bunch of information on different dog foods.
I was going to just buy some Purina Puppy Chow over at Walmart until I saw how bad it was. Looks like alot of the big name brand foods for dog are not very healthy for our pets. Its funny now to look at dog food after reading on this site. Alot of dog food like "puppy chow" is mainly made from Corn and other Grains. The ideal kind of food for dogs should hopefully have actual meats in the food. So when looking at dog food ingredients look at the first few ingredients. From what I understand the first 4-5 ingredients take up the majority of food. So if the food starts with "corn, wheat, or other grains" its really not to beneficial to our dogs. I am starting to try to look for food that has at least have some kind of meat in the first 2 ingredients. Well I hope this helps all of you guys out!

So what kind of Dog Food do you feed your dog?
How much daily?

Currently I am feeding my dog NutriSource Dog Food (Small and Medium Breed Puppy Chicken and Rice).
The price isn't too bad for a 4-star quality dog food.
I feed my dog 2 cups a day (one around lunch and one around dinner time).


Edit:
I found a link that breaks down most dog food by prices/pounds/formula.
Its pretty cool if you are pricing around for dog food.
