I agree, she is still so young and tiny. The most important thing right now is that she eats, later you can try to introduce the dry food again.
I have 2 very stubborn pickery eaters too! Right now, for their AM meal, I must 'hammer' up their dry food (Blue Buffalo and Chicken Soup for Dog Lover's) then I mixed a tiny bit of fancy/fine shredded part-skim mozzarella cheese (very small amount) and then I put some tiny (almost shredded) pieces of boiled chicken pieces...mix that all up and put it in the dish/bowl and then as a topper, I have to cut up pieces of their chicken jerky and put a few on top to entice them to eat this gourmet meal I just created...ha-ha-ha-ha...
They amaze me! Their favorite snacks are....cut up pieces of raw/fresh green beans and romaine lettuce...go figure, they have NO PROBLEM eating veggies!
