Statistically bitches score higher than dogs. It has been mooted that some of this difference may be hormonal. In the UK system there is no way to prove it, as you can only have them scored the once. The theory is that the joints may be more lax under the influence of the hormones.
I have had a bitch scored just after a season and her result was a bit higher than I had expected and hoped based on her relatives. She came back 7/7 where as most of her female and male relatives were between 9 and 12.
In future I will go for csoring mid way between seasons.
