It's OK... she has the sugar drip, and even though I'm sure she's not thrilled at being in any new place, she now has doctors and help. Stress of leaving a familiar place can bring on/exacerbate any little problems - and a doc's help will get her through it; I'll be thinking of you both tonight and for as long as it takes to make her healthy again. She is really small - Nikko was 2.5lbs at 12 weeks and is expected to make it to 6 lbs or so if we were lucky according to the growth charts... I didn't realize yours was quite so small. Hypoglycemia is much more common among dogs Meg's size, and I'm glad she's being treated for it.
As far as getting her to eat, you certainly know from this experience that eating is #1 top priority. Some people might recommend more, I don't really know, but I'm sure that everyone would agree to feed at least three times a day at this age and size. Kibble, plain white rice, plain boiled chicken, soft canned food, non-fatty chicken broth, ANYTHING if she won't eat her kibble. I think the other thread had some people who recommended some other good stuff as well. Protein is certainly important as well. Even if she doesn't eat a bunch at every meal, make sure she eats some. And if you can get some enercal or nutracal, that will be really handy to have if she starts to act weird again. Karo syrup is ok, enercal or nutracal is a smidge better because it has some vitamins and whatnot in it too (though it's still mostly sugar)... any of them, including crappy fake maple syrup, has the sugar in it to potentially whet an appetite and lift temporarily out of hypoclycemia if only given a teeny bit.
When my puppy was really really sick to his stomach from all the parasites and wouldn't eat hardly anything, all he would eat was boiled plain chicken, white rice, and an occasional baby carrot. As he got a little bit better, I made him ice cubes that had bits of his kibble in it (sometimes I crunched the kibble down into a powder to put in the cubes). Then gradually he went back to eating his kibble and his water separate and normally, as he started to feel better.
I'm sure you will get some other good advice about feeding, and about having such a small pup... please let us know when you get another update from the vet about your baby girl.
