The reason B pups cost that much from reputable breeders is because they are health tested. The parents have had the DNA Fanconi test, eye exams, thyroid tests, hip x-rays, etc. It is not cheap to have all these tests done. If anyone is paying that price for an untested pup, they need to be educated. Even my rescues have had the majority of these tests done!
You should check with breeders in AZ to see if they might have a young adult available! Under that same website, there is a section titled Breeder Referral and there is a list of states where breeders reside.
