I was wondering if anyone has any advice/experience in dog proofing a tent floor. My wife and I are planning on taking my black lab (50 lb) and dachshund on a short trip this weekend. The dogs normally sleep with us and keeping them outside overnight just wouldn't work.

I'm a little worried about their nails puncturing or compromising the waterproofing on the floor of the tent. They will probably be walking on it and occasionally they scratch the floor before laying down.

I was planning on grabbing some 2mil drop cloth from Home depot (it's light and cheap) and just cutting it to the tent size and putting it down inside before letting the dogs in. I think this should work, but was just curious if anyone with more experience had any opinions or other ideas.
