We updated our wooden deck to a manufactured "trex" style deck and the boards became too hot to walk on with bare feet.  Fearing for the dogs comfort, we purchased this outdoor rug and it not only looks great but is very comfortable on your feet; which would tell me that the dogs are happy again.  It vacuums like a traditional indoor rug, and muddy dog prints wash away with each rain.  No mildew smells, or BPA plastic smell like other outdoor rugs.  I will be buying another for our lower patio!
