As I rememeber when I use to breed dogs........ Another thing to keep in mind that if you do purchase a dog for breeding, and its a larger breed, especially one prone to dysplasia, that obtaining an OFA (orthopedic foundation for animals) certificate/rating is usually advisable. The OFA rating is shown on the AKC registration. Xrays are done by a specialized vet and read to provide the OFA rating. The xrays are done only on dogs that are over 2 years old, and for females, they must not have been bred. Responsible breeders do not breed dogs that do not get an acceptable OFA rating. When buying a pup from a breeder, its advisable to ask if the parents have an OFA rating. An option to OFA is PennHIP with Penn referring to a technique developed at the University of Pennsylvania.
OFA results are reported as Excellent, Good, Fair, Poor or Dysplastic. PennHIP results are a reported as a percentile of the distractive index compared to all other dogs of the same breed that have been tested. ... PennHIP requires general anesthesia. The best option is to use both OFA and PennHIP screening.
