I'd go to some dog shows and watch the Frenchies and talk with their owners/handlers. Also, you should be able to get a list of breeders from the local French Bulldog Club. If at all possible you should visit the breeders, look at their kennels and their breeding stock. Ask about health records, do they track the health of the puppies they sell? Also ask about temperament. Make sure both parents of your pup are friendly, people kind of dogs.
