Thank you Jane, that's a big relief. I'm so new to all this I could of easily missed something so obvious. I was sure the vet was referring to her tail colour but some things do get lost in translation.
I think a docked tail is okay for the moment but I believe it's soon to be banned in France (except for specific hunt breeds) so show cockers breeders are starting to phase it out. It was about 50/50 when I was looking at breeders.
Maybe I'm wrong about the Entropion, the vet told me that too! But I did read that ‘in principle, Entropion is a point of non-confirmation’ in France, so I guess it depends on the case and the judge. I just presumed it was the same in the UK.
I think I should just ignore the vet, he's making me paranoid. The breeder was a little pushy about me taking Lucie rather than an 8 week old pup and I started to worry it was for other reasons than the obvious. I'll probably find the papers in the letterbox tomorrow!
I found Lucie's parents tests listed, it's not an official database but it's a bit complicated as her father is German.
I don't wish for her to have a litter so the Entropion being hereditary isn't an issue.
Thanks for your help
