Welcome to the site and good luck on your search. A good place to start is go to some dog shows and talk to the people showing Frenchies. See if there is a French bulldog club in your area and talk to them, and also ask several bulldog vets in your area about breeders. Once you have found a couple, visit their kennel or home and see how their place looks. Is it clean, are the Frenchies clean, and do you get that good feeling about them. Just follow your gut, if it doesn't feel right, then move on.
