A novice owner had her bitch sored in my breed and was in tears as her bitch scored 14 (our mean vacillates between 13 and 14 so was 13 that year) as her Vet told her it was high and over the breed mean so she couldn't breed from her! I have also heard of Vets telling people they should not breed if the score was over 8.
In fact my Vets receptionist rang me with both of mine saying the scores were poor, at 14 and 15. Our median score is 12, so as a breed we have few really low scores, but also very few high ones.
Of course in breeds where the mean is high you need to choose low scores to get improvemetn, but in breeds that average in the low teens just keeping the status quo is fine.
Of course I would prefer lower scores and do take them into account along with other traits when selecting a mate, and would not use a high scoring dog. I am quite ahppy with generations of scores that stay steady at the 8 to 15 mark.
