at 14oz I cannot imangine such a tiny baby not with it's momma and littermates, I'd be scared to death to bring one home that tiny and young
Has this baby even been weaned? Did the vet say you have to feed her puppy milk through a bottle? Human baby food is ok, but does not have all the propper nutrition a growing puppy needs. You said you were young, how young are you? i have bottle fed newborn kittens before, and kept them in a homemade incubater, with heating pads underneath blankets. Hypoglcemia is extremely worrisome at this age, have nutrical or kayro syurp always on hand and rub on the baby's gums, blood sugar has to stay at a normal, even level, if too low will kill this new puppy, so you have to be so very careful. Did the vet mention wet food? wet puppy food would have better ingredients ,and buy some that are super premium high in protein. You could spoon feeding her, little bit at a time every hr. or so. I think you will need to give this puppy round the clock care, and it is not for somebody who never has had any experience taking care of such a tiny, vulnerable puppy. Can you try to find someone to help you? Best of luck with your puppy.
