What you could do is see if there is a pet store near you that has Nature's Variety products--if they do, they have a freeze-dried raw you could bring. My friend just used it as she is a raw feeder (as I predominantly am) and travels to dog shows throughout the east coast with her two standard poodles. She said it was a little messy but worked out well--

(they also have a list of vendors)
What I do is predominantly raw but I do give Riley some kibble in the afternoon (about a 1/4 cup)---I rotate between Timberwolf Organics and now started Nature's Variety kibble(they say rotating foods helps against allergies and I figure between the two brands and their options my dog has quite a menu). You may want to start that when you get home so you have that option if necessary. The other reason I give kibble is that if our power ever went out and we couldn't get to a store or something at least I know there is some kibble out there he can eat which I feel is quality.
