I am not saying anything bad about you buying the pup or reselling her. I understand she will be to small and you don't want an open font in your program.
I am happy she is going to a good home.
I posted because I didn't want anyone to think an open font meant you had a dwarf. Dwarfs are definitely physically different looking. Have you ever seen a "munchkin" cat? The body is regular size and the long bones of the legs are almost not there. Its very obvious. Its not something you have to feel for.
I will agree that the "miniaturization" of the yorkies maybe why some have open fonts. The tinies have them mostly. But that's a completely different thing.
The advise on checking for obvious stuff before buying was just a heads up for anyone looking. It can be done at 8 weeks old. That's when the first evaluation of a pup is done by many breeders.
Teeth may change but jaw bones rarely repair or get straighter, an inquial hernia can be found by standing the pup up on hind feet and looking for any bulges, (sometimes you can't see them otherwise). Top lines can go off but don't usually get much better if already roached at 8 weeks. Cow hocked legs or popping knees at 8 weeks is not a good thing either.
Open fonts found just by rubbing the head.
Any of these things at 8 weeks would rule out a breeding/showing pup.
This can be done quickly and save someone disappointment later.
Sorry I guess this is off topic and should have been somewhere else, but I didn't want you to think I was scolding you for buying the pup.
