Hi Kelly.
Important bit first. Juan Montoya (ex CART champion ind Indy winner) won the race!
I have taken the liberty of emailing you some info on hip scoring, hope you dont mind.
Yes, there are some 0/0's around but in reality, anything from possibly 4/4 down is as perfect as makes no difference and anything up to 10/10 is unlikely to ever have a problem. The mean score for Flatcoats is 9 (total), Lab's 16 and Goldens 19.
Have a look at
http://www.bva.co.uk/about/canine.html and click on "breed mean scores"
Of course, any documented results such as this is only as good at the people and if for example, in a breed only one person has their dog scored then the breed mean score is worthless.
Best wishes, John
