has any one got a long haired germon sheperd puppy which has been hip tested

Puppies can't be hip-tested. Hip-scoring isn't done before an animal is 12 months old. What you need to look for is a breeder whose stock is all hip-tested (it will say the score on their registration documents) and ideally whose stock has been hip-scored for several generations back in the pedigree.

GSD & all dogs have to be 12 months old before they had be scored for HD
