We ripped up the old carpet a couple of months ago, with the intention of installing hardwood. After looking at what has happened to the subfloor, from the big dogs' claws, I'm not sure hardwood is a good idea. They are far from rambunctious. This is just everyday living for a couple of 150 lb dogs. We are thinking about a lower end laminate floor for now, to see how that goes. Or maybe carpet tiles. Anybody have any thoughts?
