CKC is a scam registry. Avoid CL "breeders" at all costs- it's ALWAYS sketchy. Good breeders don't advertise on craigslist. In this particular ad, the parents look like they might not be purebred. Also, continuously referring to them as "Black German Shepherds" like they're their own breed is.... annoying :-p
Anyways, this ad is all scam and ripoff and shady breeding. Please don't support breeders like this. Save your money and go to a reputable breeder who actually produces quality dogs that improve the breed and isn't just out to make a buck... or look into rescue.
