Graded radiographs have shown that the
majority of dogs with grade 1 elbows display obvious signs of unilateral and
bilateral arthritis, therefore the current breeding advice from the BVA is as follows:
'It is strongly recommended that breeders wishing to reduce the risk of elbow dysplasia should select their breeding stock (both dogs and bitches) only from animals with an overall grade of 0. Dogs with elbow grades of 2 or 3 have marked osteoarthritis likely to be due to ED, with or without a visible primary lesion. Dogs with elbow grades of 1 show mild or early osteoarthritis which is also likely to be due to ED.'
