Actually they are or supposed to quite durable if they are done the right way, think about all the walking on them you do with shoes on and things like that.....well I walk on mine anyway with shoes on, A dogs pads are soft so no issue there and their nails shouldn't be a factor unless he or she has something burried under the floor lol
We have wood floors, We have scratches in our floors from having two dogs, but they aren't visible unless you LOOK for them. You can't see them really, now you can see the ding in the floor from where our lab dropped her nylabone from the second floor landing. She thought it was an awesome game! LOL! Floors are easy to fix!!
I have wood floors, and throw/area rugs around, Yes, I have a few scratches here and there, my dogs do get a little rambunctious in the house on occasion..but gives me something to do, keeping them buffed out
they'll scratch the floors, get used to it I refinished mine as well a few years ago and they put some good scratches in a few spots, but I expected it. They'll be refinished again in a few more years maybe, but I put many layers of poly on so the scratches are mostly in the surface, not in the wood. So no need to take it all the way down again
We have very expensive dark maple floors and finished building our house a little over a year ago. Our 7 lb cockapoo left no scratches whatsoever. Our beloved Zoot was 12 lbs when we got her and is now 70 lbs - she left scratches from day one especially at the doorways where she has to turn into the room but has been an extremely hyper puppy. We don't allow her to run through the house but once in a while she still gets rambunctious. GSD's WILL scratch hardwood floors so just prepare yourself for it. I freaked out the first couple of scratches and gouges from my kids but now it's just old hat.
