Definitely looks like a solid maple hardwood. Oak grain is much tighter and more pronounced.

If it were me, I would try to sand and refinish. You have that small piece, you can bring it in and have the color matched. Those touch up kits are great for smaller scratches and gouges. But your dog went to town on that spot. You will likely hate how it looks and forever be annoyed if you try to touch that big of a spot up. Just my opinion though.

I like the closet idea too. But its difficult to pry up an already nailed down piece and keep it intact.
