Glad you are doing your research.
There is WAY more to choosing a breeder than cost and if they ship puppies. Champion bloodlines means nothing....you can look at BYB pedigrees and find Champion bloodlines only a generation or two ago.
First of all.... what titles do the sire and dam have? Are they both Champions or at least major pointed? Do they have any obedience titles? do they have a CD or a CDX, or anything behind their name?? Why are these breeders breeding these dogs? are they worthy of being bred? If they are doing things with their dogs, tracking,herding obedience, showing...it means they care about their dogs and the breed.
What OFA certifications do they have...just hips in not enough..there must be hips, elbow, eyes and heart...and you can go to the OFA website..
Orthopedic Foundation for Animals and put in the sire and dams registered name in the box on the top right hand side.
Breeders that you have not met and know nothing about you....have red warning flags flying for me, because they will ship.
Most COE breeder will want to meet you, or at least know of someone that knows you and your reputation before they start shipping a puppy.
Are there no breeders within a days drive for you to look at and at least meet the breeder and meet their dogs?
People can put anything on a website...they can also talk sweet and tell you the things you want to hear.
Move slowly....cost is the last thing you should be worrying about...honestly. If you get a poor tempered, HD dog....it's not going to help you that you saved $400. on it.
