WELCOME!
So glad the problem was not parvovirus or something like that.
I've had two Yorkies, but others here have had more experience - but.....if your baby is eating well now and not having tummy or diarrhea problems I would tend to stick with what the vet recommends. Your pup is young and diarrhea and vomiting could cause dangerous MAJOR dehydration that is fatal to those young ones and can happen very fast! Later when she is more mature you could then decide what food you prefer.
Many read DOG FOOD ADVISOR on the Internet. But again, you pup is so young and I would stick with the vet for now. I'm sure others will weigh in and give their take on this issue.
Again, WELCOME to you and your DIVA
We love pictures!
