Teensy scratches

Q: I have a small dog that has left scratches on my hardwood floors in my foyer. I have butterscotch colored hardwoods, but some of these scratches have left visible marks I suppose where the coloring has been stripped (the scratches are lighter than the floor as a whole).

How would I fix this? Do I have to have my floors refinished, or is there a filler of some sort, or an easier way of fixing these scratches?

A: This sounds like a pre finished floor with aluminum oxide coating. Hard to deal with. You could try to buff and coat the boards involved, but I doubt it would change the light colour of the scratch. A coloured marker might be a better temporary fix. Another reason why I don’t like pre finished floors.
