Yeah I read that food that is more expensive is actually cheaper in the long run because you feed less, which also means less waste...which is good on walks! I feed my dogs Science Diet small bites and they have done well on it- if you buy the big bags they are cheaper per pound (a 40 lb bag is between $28-35 depending where you buy it around here) and Petco has a buy 9 get the 10th free program if you've got one.
