The problem is that with the widespread serious disease in this breed, all breeders need to be working together. Little will change and the rate of affectedness is only going to get ever worse if many breeders continue to breed without getting and using scan information about their dogs. this is exactly the same as breeding dogs without ever listening to hearts and just hoping that from outward appearance you can tell how healthy a dog's heart is. Just as with SM, the disease can be very bad before you start to see outward signs with MVD. No intelligent breeder would ever accept that this is an ethical approach to heart health in cavaliers; why is it considered okay to do this for a serious neurological condition that seems to be just as widespread or heading towards being that way?
There is also the issue of fairness and commitment. It is all very well for a single breeder to state that she or he has the choice or not to use EBV's -- but the only reason any breeder has the opportunity to use them in the first place is that other people have scanned their dogs and submitted results, and any breeder that uses them is benefiting from what others have done. In other words every EBV is built on the cooperation of many breeders. Moreover, the breeders who choose not to scan and not to submit results are damaging the EBV system. Every time a breeder chooses not to scan, that detracts from the overall knowledge and big picture and the accuracy of every single EBV. In addition, if breeders only submit their good results, the EBV's will be skewed to present a far more positive picture than actually exists and all the effort and money and consideration that has gone into setting up the program to benefit breeders and the breed as a whole will be undermined to some degree.
I cannot stress enough how important it is for every pet owner who has had a dog scanned -- if that dog has a pedigree and is registered -- to submit those results to Sarah. Pet owners tend to scan because their dogs have problems and therefore they are far more likely to have the essential information on affected dogs that will make the EBV system more accurate.
Also, breeders and pet owners need to verify with the person doing the scans that they are submitting the information to Sarah. There is no organized attempt to do this, it is up to the individual doing the scan. If you have scanned dogs it would be worthwhile to check with the center that scanned them to make sure the results went to Sarah or to submit the results yourself making a note that you aren't sure if they were submitted.
