----- Original Messages ----- "i also personally know of a dog now deceased who was OFA good and NZ." "If not all the same criteria is being looked at under the two systems, the differences might be part of the reason for the different evaluations." "when i talked to ofa about 5 years ago, they didn't know anything about the german ratings." One major factor is the German x-rays are done at 12 months, as opposed to OFA's 24 months, One of the best producers of hips, Marko Cellerland, was NZ at 12 months. We bought a little bitch who was NZ at 12 months. She went good and was our best "OFA Excellent" producing bitch. I think the best you can do as a breeder is breed a dog free of dysplasia from family lines with high % of good hip production, and pray. All of our OFA excellent offspring have come from 3 sire lines that were known for producing high number of OFA excellent. Here's a comparison of OFA vs other systems, plus an explanation of OFA rating system. http://www.offa.org/hipgrade.html Rachel & the Ark "The whole question is not only a question of the dog/horse, but quite as much, if not more so, a question of the fitness of the leader."
