That also depends on what your opinion of "high-quality" is, especially with dog food. The majority of cheaper dog foods (Beneful, Kibbles n Bits, etc.) is corn. That's really all it is, corn mixed with some animal fat. Try a dog food such as Nutro's Natural Choice (usually about $20 for a 50lb bag), but supplement it with meats and fresh fruits, veggies, etc. It isn't a fantastic food, but it is still cheap, and much better than Doggy Bag or other brands commonly used.
