How many german shepherd dog breeders are there in Pennsylvania?

I'll be moving to pennsylvania soon and I would like to know if a german shepherd is a popular breed in pennsylvania so that I can buy one from a good breeder.

How are we supposed to know how many breeders of a single breed there are anywhere ? When you get there look on your computer for local breeders .

There has to be atleast one

Here is how to find a reputable breeder.Once you have decided on the breed you are looking for, visit the internet and find the NATIONAL BREED CLUB for your breed. Review all the information about the breed and find the web pages or phone contacts of breeders that are listed there. National breed clubs almost always have certain standards and ethics quides for any breeders which are listed on their pages.Step2Prepare a questionnaire of questions you want to ask the breeder. This is a good one:What health guarantees do you have?Can you give me a vet reference?Can I visit your kennel and if so, when?How long have you been breeding?Do you enter your own dogs in AKC events?Can you send me a sample copy of your contract?Do you sell your litters to pet stores or brokers? (there is NO responsible breeder that will sell to a broker or a pet store, since it is too difficult to follow through on who is getting your puppy!!)The LAST question should be "how much do your puppies cost?" but it is of course an important questionStep3Do make plans to visit the kennel and while there check the following things:Are the dogs healthy and happy?Does the kennel owner know each one by name?Do the dogs have places to run outside their pens?Are the pens clean and roomy?(even if the home is a mess or in an uproar and not very neat, the kennels should be clean and all dogs should have food and fresh water available)Is the whelping area in the house?(puppies should be raised INSIDE a home for at least the first four weeks in order to get all the necessary social and physical attention needed in the first few weeks)Do the sire and the dam act friendly and sociable?(sometimes the STUD dog may not be available, the female may have been shipped elsewhere for breeding)http://www.ehow.com/how_2256622_responsible-dog-breeder.htmlWhen looking at puppies ask to see, you must see, the results of the parents OFA ( Orthopedic Foundation for Animals ) scores for hips, elbows and patella. Also ask to see the CERF ( Canine Eye Registration Foundation) BAER (hearing) and Cardiac results. Do not accept any excuses for not having them a reputable breeder can show you. They can also trace the parents lineagefor several generations. If the sire was off site they will still have the proof. They can provide a pedigree of the pup. Not just registration papers. Pedigree means they can list at least three generations back from the pup. They can tell you the pro's and cons of the breed.Why not find a Shepherd rescue or go to local shelters. You could save a life!
