Show. Is there a diff with regards to hip scoring?
No not at all its just I could have pointed you in the direction of a hipscored database for working cockers, still in its infancy but is growing all the time. Hipscoring in cockers from working and show lines is still very rare unfortunatley so as said before you may struggle to find breeders who do hipscore both parents and TBH you would probably expect to pay a bit more for pups. One thing that hasnt been said is that its also possible good scored parents can still produce HD pups and while its seen as reducing the risk of buying a pup with good balanced hips its still no guarentee. I would tend to look for equal scored hips in parents too, or as close as possible, i,e 4/4 hips in its score, even if the score is a little higher than the breed average.
