Definitely bring a rug or a footprint for the inside, just to be safe. But honestly, you need a high-quality tent material. Coody camping tents use really thick heavy-duty materials for the floors and the walls. The mesh is much stronger than the cheap stuff you find at big box stores. My dog jumps against the door sometimes and it hasn't ripped yet. The layout is open too, so the dogs have plenty of space to lay down without blocking the exit. Get something durable from Coody..us.
