The cat is just establishing who is boss - her. As long as there isn't any serious damage done, I wouldn't worry about it. This will be one dog who respects kitties - and that's not a bad thing. Just keep an eye on it, but with that smoooooooth Weimy coat, you'd be sure to see any actual scratches. If she dislikes water (some cats don't, and this would not work for them, [right, Pippin?]) keep a spray bottle with just plain water in it and squirt her when she goes to attack the pup.
