Which is the better food? One costs 27.99 for 34 pounds at PetSmart and the other is 49.99 for 35 pounds.?

the food's that start with meat not meat byproducts are always the best. if the main ingredient starts with corn, or meat byproduct it's not the best choice. another product to stay away from is corn. dog foods that have rice in them are the best for digestion.crude protein is also important the higher is usually the better. the first ingredient tells the story as far as the quality of the food. hope this helps
