You can always order food on-line (it would save you the driving time).
Some good brands that I recommend are:
Merricks (any flavor)
Canidae All Life Stages
Chicken Soup
Innova Evo
Timberwolf Organics
There are many more but these few just came to mind. You can also check out this website that rates dog food. I only buy 5 or 6 star food.
