Moto hit the nail on the head. With the amount of gas you would expend pay the extra and have it delivered. I would contact the nearest Timberwolf distrubutor, my geography is challenged so if I'm wrong I apologize, I think that would be the lady in SC. It's well worth the expense.
She's a very nice lady and I'm sure she would be willing to help you out. Keep in mind for such a young pup, 15# is plenty. You would want the Wild and Natural formula. If you can split the bag in half, seal the unused portion till you need it, so much the better. It's very fresh, for kibble, and it will go rancid if you don't feed it in a month. I know this for fact since I've dealt with the diarrhea that is the result.
If you would rather do the drive then the Canidae is better than Natural Balance, Wellness would be another step up from Canidae.
I remember living in San Antonio(1989) and trying to find decent food(Nutro
). We had to drive 40 minutes to get it, what a hassle.
