A pink-haired Pomeranian named Preston Casanova is one popular son of a bitch.

The canine with the crazy coif from "Greatest American Dog" got the star treatment at The Grove shopping mall in L.A. this weekend. The finale hasn't aired yet, but if he wins, the pooch could make a big dent in that $250,000 prize money shopping there.
