Never ceases to amaze me that people have dogs that are tent-safe. Any of the dogs that I've had would destroy a tent the first time they heard another animal. The ones I have at the moment wouldn't even need that much, they'd just start to play and a bit of thin fabric wouldn't slow them down at all.
If I were to take them anywhere camping (not that I'd think it could ever really be safe for all concerned) I'd be thinking about a tarp, a surplus bivvy bag, some chain and a good ground anchor.
our borders are fine in the tent- the youngest one sleeps in my sleeping bag with me ( or in with one of the kids if they are with us) and the older usually on the bottom of my sleeping bag. they usually take themselves off to bed when it starts to get dark and there till morning!!
