AKC registration PAPERS do NOT tell anyone ANYTHING (health, quality, whether the breeders are reputable) other than that the puppy itself, is a PUREBRED, whose parents were also registered. Therefore, having "AKC" papers does NOT mean you have a dog from a reputable breeder. That is how puppy mills get their hands on to these "papers" - they breed purebreds. literally, anyone who buys a purbred dog (who is registered) can mate that dog w/ another AKC registered purebred, and their puppies will be able to get AKC papers too. But you would never know if these dogs are sick, has is dying, or was mistreated, or tortured! So long as one puppy mill gets their hands on 2 AKC registered dogs, they can start to breed- but they breed for smaller size bc its a "fad" and treat their dogs like machines, and can not care less if the puppies die b/c these mills are using RUNTS to breed. it is just a horrible cycle.
When I recommended to look @ AKC for breeder's, that is because if you actually click on the AKC registered breeder's LINKS, you will see, there are VERY FEW AKC RECOMMENDATED breeders in each breed! the REASON for that is bc these breeders have established their reputation for ETHICAL and LOVING breeding methods, BOTH in dog shows AND in sales for pets.
In essence, I guess what I am saying is, AKC PAPERS are just documents to show your dog is a purebred. thats it. it is up to us (buyers) to do our RESEARCH about the particular breeder. Ask questions, like : where are the puppies' parents? can i see them? pictures? if the breeder claims the puppy is from a show dog, ask for a pedigree. EVERY show dog winner has one. it is very easy, if they give u excuses, RUN! ask them HOW OFTEN they breed a year. also GOOGLE their kennel's name! it sounds "funny" but often, you will find TONS of info!!
