She’s very bright for ghi alone, they are usually pretty dark. She’s either a really nice ghi or ghi OD but IMO, the breeder would make the best judgment especially with that pairing because they would all be either ghi or ghi OD and it should be much easier to tell if she has OD if you have her to compare with her siblings. So maybe if he’s a good friend, he just gave you a ghi OD at ghi pricing. If the breeder said it’s just ghi though, I’d probably go with his judgement. Beautiful girl you got either way.
