what does Fast Normal and NZ mean? - Page 2

Odds are great that a dog that is clear at 12 months is also going to be clear at 24 months. The rating depending on whether or not the dog was sedated and the quality of the xray. The SV needs to raise the age to 24 months for a permanent rating and the OFA need to require sedation to the point of relaxation. Otherwise it is on the owner of the dog to do it right. Don't send your xrays to the SV til the dog is 24 months old and don't insist that vets xray your dogs without sedation. Sedation is not anesthesia, not dangerous and allows the dog to become relaxed and not resist the manipulation. It does make a difference in some dogs. I've seen it. Either one wants to know the true status of their dogs's hips or they only want a certification.

It might also be a great idea to not use dogs rated NZ and fast normal. It's generally not acceptable to breed a GSD that is so so in conformation,  protection, a performance venue. Why is it acceptable to use a dog with so so hips? Other breeds have reduced the incidence of HD dramatically by only breeding normal hips to normal hips.  It's common for entire litter to clear. I don't see that happening often with GSD's. Why?
