The foremost objective in breeding should be to improve the breed by breeding to a breed standard. If a bitch has a fault you would not breed it to a dog with the same fault, you would always look to improve on what you have.
If your aim is to achieve a lower hip score and you are breeding from a bitch with an average breed mean score, then breed to a dog with a total single digit such as 3:3 = 6
According to Dr Malcolm B Willis BSc PhD senior lecturer in animal breeding and genetics, honarary associate of the Royal college of veterinarian Surgeons who has been analyzing hip displasia for many decades, breeding a double digit hip score bitch to a single digit dog should result in puppies with a three point improvement to the breed average.
For example, in the Utonagan the breed average is 20, breeding a bitch with a total hip score of 18 to a dog with a hip score of 6, should result in puppies with hip scores of 15.
Hip scoring is done in the United Kingdom under the BVA/KC. It involves taking an x-ray of the dogs hips once they are over 12 months old, the best score a dog can get is 0/0 = 0 and the worst 53/53 = 106

Several factors can influence the hip score a dog achieves
Age
Diet
Excercise
Hereditary
Eye Test.
The BVA Eye Scheme is primarily concerned with the examination of the eyes of dogs for inherited eye disease, but also includes a general examination of the eye and adnexa - this includes the lids, lacrimal apparatus and orbit. The BVA Eye Scheme offers breeders the possibility of eye testing to screen for inherited eye disease in certain breeds for certain known conditions. By screening for these diseases, breeders can eliminate or reduce the incidence of eye disease being passed on to the puppies. Not all breeds have inherited eye disease and, for reassurance, any breeder can have their dogs eyes examined under the scheme, even if the breed is not mentioned in the Eye Scheme Literature. In general the best age for eye testing is before the dog has reached one year old and thereafter on an annual basis. Some breeds, however, it is necessary to test them as young puppies, usually between the age of six and twelve weeks.
