We currently have "distressed" oak floors. We refinished them 5 1/2 years ago but the dogs' nails leave dents in the wood. Instead of using a polyurethane finish our finisher used something called Torginol. There a barely any scratches in the finish even though there are lots of grooves in the wood. I try to keep the dogs from running but I'm the only one - everyone else throws balls inside (upstairs) and of course the dogs don't care either. It doesn't bother me too much but hopefully the distressed look will be fashionable if we ever want to sell this house.
