Let me give you another thing to think about before you get the dogs. We have a big dog and he has been fine on our wood floors (real wood) as far as scratching them. HOWEVER, he doesn't walk well on them. He is part golden retriever. Now that he is older, he is having a lot of trouble getting up and down because his feet slide. He also has trouble cutting corners. Also, my in-laws had a dog (smaller, 35 lbs, I don't remember what kind!) and because of the tile/wood floors, he walked funny on the floors (with his back feet turned) and eventually had lots of hip problems due to the floors.
I know lots of people have these floors with dogs, but if I had it to do over, I wouldn't have both because it is really sad to watch your dog try to get up.
Good luck!
