I have come across some interesting information and would like to learn more. If retinal folds are allowed under cerf, but dogs with folds should not be bred together why? And if folds, geographic dysplasia and retinal detatchment are related defects how then do they allow folds. Is not one just a more extreme expresion of the next two deffects? If one should not breed two dogs affected with folds will they risk producing gd or rd? testing puppies under 9 weeks can show folds that will later cover over, but why bother, if folds are not a problem? Can one test breed a dog with folds to one who is thought clear and then test their puppies to see if the pups have folds or even gd or rd?? Are folds gd and rd similar to Collie eye annomoly in their mode of inheritance when in CEA you can do a test breeding to a known carrier or affected dog to determine if the other dog is a carrier and not affected? A percentage of the puppies will test clear, and a number affected. However the "clear" pups would be carriers like the one parent that was being tested. It takes two carriers to produce affected or carriers. OK I am listening. Leah Swatko Ministik reg. [EMAIL PROTECTED]
