Your girl is adorable. Don't ever think otherwise. Just enjoy what you have and feel blessed that she is loving you in return and is healthy.
That being said please remember that these babies are just like human babies in that we don't know how they will turn out. Only can hope for the best but each one is different.
Thats why I have so few show pups but more pet puppies.
Your girl is sweet and I too have found faults with a couple of mine that I spent BIG money on only to realize when they were grown that they would always be just lap warmers
Doesn't make me love them any less and wouldn't ake a million dollars for any one of them. They will be with me till they cross the rainbow bridge.
