BVA/KC Hip Dysplasia Scheme
The current BVA/KC scoring scheme for hip dysplasia (HD) has been in operation since 1984 and since then over 100,000 X-rays have been assessed. Dysplasia means abnormal development, and the degree of hip dysplasia present is indicated by a score assigned to each hip. The hip score is the sum of the points awarded for each of nine aspects of the X-rays of both hip joints. The minimum hip score is 0 and the maximum is 106 (53 for each hip). The lower the score the less the degree of hip dysplasia present. An average (or mean) score is calculated for all breeds scored under the scheme and advice for breeders is to use only breeding stock with scores well below the breed mean score. The mean score for labs is 15.
The minimum age for hip scoring is one year, and each dog is only ever scored once under the scheme.
BVA/KC Elbow Dysplasia SchemeThe current BVA/KC scoring scheme for elbow dysplasia (ED) was launched in 1998. Dysplasia means abnormal development, and the degree of elbow dysplasia present is indicated by a grade assigned to each elbow on a scale of 0 to 3 (0 being the best and 3 being the most severe). Only the highest grade of the two elbows is taken as the elbow grade for that dog. The minimum age for elbow grading is one year, and each dog is only ever graded once under the scheme. Advice to breeders is wherever possible to use only those dogs with grades of 0 or 1 for breeding.
DNA test - prcd-PRA
prcd-PRA (progressive Retinal Atrophy) causes cells in the retina at the back of the eye to degenerate and die, even though the cells seem to develop normally early in life. Owners of affected dogs first notice that their dog becomes night blind, but this eventually progresses to total blindness. The age of onset of first signs varies from breed to breed, however, in all cases puppies are born with perfect vision and their sight begins to degenerate later in life, from around 3 years of age or later. The condition results from a single recessive mutation of a gene known as prcd.

BVA/KC/ISDS Eye Scheme
The BVA/KC/International Sheep Dog Society (ISDS) Eye Scheme offers breeders the possibility of eye testing to screen for inherited eye disease in certain breeds. By screening breeding stock for these diseases, breeders can use the information to eliminate or reduce the frequency of eye disease being passed on to puppies. At the centre of the scheme are two schedules: Schedule A and Schedule B.Schedule A contains a list of breeds and eye conditions that are known to be inherited in those breeds. Under the Eye scheme one of a specialist group of canine ophthalmologists (the Eye Panel) examines a dog to look for clinical signs of inherited disease known to affect the breed in question. If no clinical signs are noted for these diseases, then the dog is declared ?unaffected?; if signs consistent with one or more Schedule A conditions, then the dog will be declared ?affected? for the relevant disease. These results are passed to the KC for inclusion in the tested dog?s registration database. Only the results of Schedule A examinations are available to the Health Test Result Finder.
