I dont know of any in the Baton Rouge area, but speaking from an experienced DP owner (4) myself; you've choosen a very good breed of dog..... Very devoted animals and one of the most loyal I've ever come across.... Good luck on your search.
Thanks. A friend of mine has a fawn Doberman and it's one of the sweetest dogs I know. He looks intimidating and has a mean bark, but on the inside he's just a big ol' baby. I'd prefer to find a breeder as close to Baton Rouge as possible but most anywhere in Louisiana would be okay.
