You can get collapsing kennels if your dog is properly kennel trained and won't try to chew them up. I've got two that are built like a tent, the smallest packs down to about 6 by 19 inches for a 36 by 31 tent, plent of room for my 70 lb lab mix. Called a pack-a-pup tent. I bring that with everywhere, and set it up if I think she needs a refuge.
