You have a choices.
You can put the car in the garage under a cover and uncover it once a week, sip a beer and stare at your beauty then cover it back up and drag it out the following week for another sip-beer-stare-at session.
Or you can drive it and enjoy it and learn to live with rock chips, door dings, dog scratches, etc.
Blaming the dog is not an option.
Your problem clearly falls under the "shit happens" section of life.
