LOL @ Kayc - just imagine black lab puppies swaggering along in their leather studded jeans - chewing the backside out of their litter-mates' genes!
All we can do, Velvet, is keep plugging away, advising people who come looking for puppies, that they MUST check that parents have been hip scored (with scores like yours or even lower, if pos) and with current good eye test certificates.
Someone posted on here that they enquired about hip scores for a German shepherd litter, I believe, and was told that "the puppies have hip scores of 2"
