Dog pee damaged hardwood floor
I have rugs on my hardwood floor. One day, I lift my rug for cleaning and found that my dog urinate soaked through the rug and damaged my floor. There is a black color around the hardwood piece. On the piece, the surface is not smooth anymore, I guess it is warped now. Here are my questions.
1. for just the appearance, how can I get rid of the black color around the hardword piece? So it does not constantly reminded me that my dogs are killing me.
2. How does this type of damage really get repaired? Do I need to called an expert? How much does it cost to repair?
Any advice would be greatly appreciated. and yes, my dogs need more training.
