Maple is notorious for showing every little minor surface scratch. The tight grain pattern hides very little. Any wood coating, whether applied in a factory or on-site, is essentially a sheet of clear plastic. Walk on this clear film with shoes or allow your pet to skitter across it and you will put mars and scuffs on the surface of that film. The fact that you can see marring of this film in a certain light would not ordinarilly be a legitimate warranty claim.

The warranty from the manufacturer (Hartco/Armstrong?) will list what is covered by the finish portion of the warranty and what remedies there might be.

Some of the 'doggie damage' may also be denting from the dog's nails and not simply scratches.

You may have little recourse with either the dealer or the manufacturer. Many a manufacturer is guilty of 'overselling' their products' features.

You don't have a leg to stand on. Dogs nails are known to add character marks to the finished surface. It is not the responsibility of the wood or finish manufacturer, to remove the dog from the wood floors.
Normal foot traffic is not damaging the finished surface, your dog however is abusing it.

So is maple a good choice for flooring? It's touted as one of the hardest floors; it looks like I may be mistaken in assuming that hardness would equal no scratches from pets (front declawed cats in my case) or smudges from shoes.

I'll try to repost an old post I put on this forum a year ago. I was the district mgr for Armstrong Flooring, Bruce, Robbins and Hartco. Scratching is not warranted by anyone. The hardness of the floor has little to do with anything. As pointed out you are walking on the finish. The clearness, or character of the wood will help mask scratching should they occur. Maple being a clear grained wood does little to mask these kinds of problems.

Most pre-finished wood flooring has a semi-gloss sheen. Surface scratches will be less noticeable with a satin or matte finish sheen. Durability is generally just as good with satin or matte finishes because they are made by simply adding flattening agents to the gloss or semi-gloss mixture. So if you desire a clear maple floor, you might want to consider this.
