Our Code of Ethics Breeders have a previous recommendation from 1 of their peers and are not breeding more than 2 breeds of dogs. Breeder is expected to do health testing that is appropriate to her lines. Puppy buyers are encouraged to ascertain what health testing a breeder has done on puppy's sire and dam. You can see the stats on health testing at this site: Stats Answers to many of your questions can be found on the Orthopedic Foundation for Animals website. If you have questions that you need to ask your potential puppy breeder, please don't hesitate to do so. All health information should be revealed to you as a puppy buyer.
