Welcome to Yorkie Talk. How old is the pup?
It does seem like she is very tiny, and reputable breeders keep the pups until at least 12 weeks and sometimes longer for tiny ones, hoping to get them up to 2 lbs.
Adult weight is often estimated to be double the weight at 12 weeks. If she is 12 weeks then she would be charting to be 2 lbs 4 oz, although that "rule of thumb" does not always happen.
I do hope that you are watching this pup closely around the clock, due to her tiny size she needs extra care. Are you aware of signs of hypoglycemia and how to treat it? I would be concerned if she seems lethargic, and possibly that is what you are seeing as non responsive to sounds. If that is the case, you need to make sure she is eating, and have some Nutri-cal on hand to put on her gums if she has signs of low blood sugar.
I am happy to hear you have a vet appt already, and hope it all goes well. |
