Your question can't really be answered canonically, but there are a few things you might do:

1. Train respect for barriers like crates, baby gates, and especially tent fabric.
2. Train a bomb-proof recall.
3. Bring a soft-sided dog crate with you into your tent, and ensure the dog sleeps there.
4. Keep your dog on a hands-free leash outside the tent while you're camping.

If your dog has a very strong prey drive, safety management is simply more pragmatic than desensitization training, especially when you don't have all the required stimuli handy to train with. Your mileage will of course vary.
