excellent advice, thank you all!
you listed so many things i hadn't considered.
we went to a secluded spot in the Los Padres National Forrest, and because we had so much fun, we are definitely going to to camping with the pup a lot more. he even carried his own little saddle pack with water in it on our hike and was a real trooper.
he didn't eat much at all while we were there, so i'm glad that's normal. . .
we are going to a fishing spot with him in a few weeks, so we'll see how he does with that. i am expecting some pretty funny stories.
