Hello and welcome. One good way to find a reputable breeder is to find local AKC sanctioned dog clubs in your area.
Do a search on the AKC website for conformation or breed club in your state or surrounding states. These clubs usually have a breeder referral contact person who should be able to point you in the right direction.

Try to avoid the internet since most of those lovely ads are puppy mill scammers. A reputable breeder will have a website but they do not come up unless you do a specific search for them.
Hope you find a lovely puppy.
