What does a preliminary OFA mean?
A preliminary OFA means a dog had their hips evaluated before two years of age. It can tell you how the hips are looking at the time. Keep in mind though that certification cannot be done until the dog is two years of agewhybecause that is when the dog is fully mature physically. The OFA preliminary can definitely show different results than the certification because the hips may change slightly with maturation. The difference though is usually only a grade or two Breeders may do a preliminary OFA on a dog they want to show, because they would not want to spend the time, effort and money on a dog that does not have promising hips.
