Between  the  years 1991 - 2004 The  number  of  X-rayed  Valls  is  343  and  the  number  of  dogs  with  "serious"  HD - grading  (HD  D or E ) is  only  14. So  the  number  is  quite  small. But  if  we  count  in  the  dogs  with  Grade C  the number  rises  to 79 dogs  thus  making  the  percentage  of  dogs  with  "not  considered  healthy" hips  23%.
However:  a  Vall  with  C  hips  is  still  considered  having "normal" hips  and  is  allowed  to  be  used  for  breeding.
