I’m up against a similar issue as I’m getting one of my dogs into K9 Search and Rescue. When/if we deploy I’m expected to pack 3 days of food for myself and my dog. Obviously my frozen raw mix isn’t going to work with this scenario.
I’m still researching, but my intent is to find a good, freeze dried raw food (I found one that comes in flake form, so I think I’ll be going with that) that can be reconstituted quickly with water. That’ll keep the weight down in the pack as well.
Just remember, as long as you keep it to a quality food that you trust, you shouldn’t have to worry too much about variance from your dogs regular food as (I’m assuming) you won’t be changing their diet up for a really long time.
Finally, and this is just my two cents, it seems to be easier for adult dogs to switch back and forth on food, while puppies need to be transitioned over a week or so. If it were me, I’d try to stay consistent until the pup is older, ie, no trips for a bit.
