Containment - Pets & Wild Bird at Mills Fleet Farm
For travel you can't really beat the fold up cage style kennels. They pack flat and assemble really easily. Around here they are carried at Petco and PetSmart but the best deals are at Fleet Farm.
For the Houdini dog you might try a reusable/removable tie-wrap to lock the latch closed. They don't last a really long time, but if you get a package of dozens, it doesn't matter.
We didn't kennel our (now deceased) cockapoos. They each had their own line and did a reasonably good job of not wrapping themselves together once I figured out where to put the stake in the ground. Close enough to get into the tent and far enough from the trees to stop them from wrapping themselves around a tree. We did have to untangle them from each other from time to time, but traveling with dogs isn't a maintenance free proposition. All part of the camping experience. These days the rescue dogs will be staying at the local doggie Hilton for long trips. Short trips? We'll see. Neither of them has been camping as far as we know. Maybe I will feel differently after that first trip with these two.
