Hi, BarbieDollOx,
My next advice if the 14 days is up tomorrow is to call New York State Department of Agriculture and Markets who oversee the puppy dealer permits and breeder's licenses. Tell them the story and have the paperwork that she gave you on hand when you talk to them.
They will help and also they will be interested in the breeder to see if she is licensed. Also, contact the Humane Society in your area if there is one. The one upstate is Mohawk and Hudson River Humane Society. They are ALWAYS interested in puppy mill stories, not to say she is one but if you get them on the bandwagon, they will give you all sorts of info on what to do about getting the lemon law enforced.
Also, did you Google New York State Puppy Lemon Law? That may be all you need to do to get the info to take it to the next step.
As far as the Emergency Vet, the low blood sugar label that gave to the situation is really what hypoglycemia is to a point. Thankfully, I'm no expert on the subject but I believe that is how it starts and maybe if it is untreated, it becomes hypoglycemia. Someone on here can answer that better than I can.
Watch her closely, and if you have a syringe to give liquid meds, you can put sugar water in it and squirt it in her mouth so she gets water and it will keep her blood sugar up.
Try not to stress, you need to keep calm to keep an eye on her.
Stay in touch.
