Hello Alison, I don’t know what you know about modern health testing, so I’ll assume nothing, because things have developed in recent times.
Hips first. The KC in their wisdom have changed from Breed Mean Score to Breed Median Score, which appears as a stroke of a pen to have improved scores over night! So although the median is now 9 total, (left and right hip added together,) I would not rule out a pup where a parent scored up to 12, provided both sides were reasonably equal, (within a point or so)
Elbows. The rule use to be to not breed from an elbow score of greater than one, but the recommendation now is to only breed from dogs scoring zero, which I think is sensible.
Eyes. There should be a current clear eye certificate.
DNA tests. There are so many DNA tests these days, many for conditions so rare that they can safely be left as diagnostic tools for vets, but there are a few which I would want to see carried out. One is the test for PRA, (Progressive Retinal Atrophy.) Because PRA tends to be late forming, possibly 6 to 8 years old, the visual BVA test is often too late and the dogs concerned do not develop cataracts until way after the pups are born, where with a DNA test we know the status before mating so can completely avoid this disease. CNM (Centronuclear Myopathy) is another worthwhile test, as is EIC (Exercise Induced Collapse) These are probably the most important tests, and speaking personally, I would not entertain the thoughts of a pup where at least one of the parents had not been tested clear for all of these. Two other tests which are desirable, but probably (to me) not quite so important are HNPK (Hereditary Nasal Parakeratosis) and SD2 (Skeletal Dwarfism)
