With any breeder you want to look at their track record. Do they have healthy pups? They should breed for health and temperament first. Visit the kennel, look at the mom and dad and the litter. Talk with people who have bought pups from them. What kind of health guarantee do they have? Go to dog shows and talk with the people who show Frenchies. Find out what kennels are having litters. Try to buy locally or as close to home as possible.
