How will these hold up to dog claw marks? Looking to put this in the dog's playroom in the basement. Thanks.

There is potential for pet claws to scratch the surface of our 8mm Sport-Lock Rubber Tiles or any of our rubber flooring. This will not destroy the integrity of the flooring but will just cause some unsightly scratch marks overtime. You will typically only see scratch marks from pets when they are clawing at the flooring, not when they are walking or running across the floor.
