Hip Score Golden Retriever. From reading the below apparently 0 should be favoured for breeding dogs but apparently 1 can be OK. With BVA in England breeders are allowed to test each dog only one time.

3 Jul 3 2012. Since dog breeds vary widely in the incidence of hip dysplasia this allows individual dogs to be compared with. Each hip joint is given a score between 0 and 53 and a total score is reported eg.
If the breed improves and all dogs in the breed have a hip score of 5 then the dog with the score of 10 will have a high EBV.
For example a dog whose hip score and the hip score for all its family is 10 will have a low EBV if the rest of the breed has a hip score of 20. For example a dog whose hip score and the hip score for all its family is 10 will have a low EBV if the rest of the breed has a hip score of 20. Of course you have to remember that a dog just like us has two hips so a perfect pair would be written down as 00 and the worst possible as 5353 The right hip is always the first figure and the left hip the second I have to say that there are not that many. Hip dysplasia is an inherited instability of the dogs joints.
