answer:I don’t have any of the cool radiant heat stuff. I do have a big dog and a pine floor. The dog does track in dirt, but I have the pine Varathaned or something similar, and her nails don’t make a dent. However, a) the Varathane darkens from creamy to honeyed with UV exposure, so it’s good to move the furniture around quite a bit in the first couple of years. b) moving furniture around by sliding the far end, without another person to pick up (as opposed to slide) the other end, will rake big canyons in softwood. c) Heavy furniture, or light furniture with heavy people sitting in or on it, will leave pockmarks over time. I love my scratched/scarred pine floor and you will love yours.
