Aww she's very cute. Her coat is too full/fluffy to be under 8 weeks of age.
She is very small....and you must be extra cautious to prevent hypoglycemia. There's a great risk for this with tinies. Make sure she eats frequent meals. Give her nytrical once in the morning...the evening and again at bedtime. Do not leave her alone for extended periods of time. Should she ever act wobbly or not able to hold up her head...immediately rub karo syrup on her gums and get her to the vet pronto.
Personally I would switch to a vet more knowledable about small breeds.
