Please note I have never gone camping with my dogs, but I think it would be super fun!
I would bring various leashes (lengths) and a long line/tether. A tag collar, plus a secure collar that youre attaching the leash to (and dont mind getting dirty!) Biodegradable poop bags if you're worried about cleaning up after him. Food/water dish. Supply of fresh water. Portable crate if you want him to sleep in a crate, secure crate if you will be leaving him alone at any point. Anything you may need for an impromptu training session (treats, certain collars, certain toys). Chew bones to keep him occupied during down times. Definitely make sure he's on a flea/tick prevention, and I'd check for ticks daily. A spray that helps keeps flies and mosquitos away and such would also be a good idea.
I would personally have my dogs sleep in the tent, with Abrams in a pop up crate, Cynder loose.
Concerns, besides bugs, would be security (especially if your dog isn't off leash reliable) and eating something icky. Abrams likes to chomp on various plants when in the woods, and I'd have to watch him closely to make sure he's not eating something bad for him.
Depending on where you're camping and for how long, may not hurt to pack a dog first aid kit. For torn paw pads, cuts from thorns, etc., etc.
