Welcome!! I am a newbie too and my baby was 1 lb when I got her. Yumi also had an episode with hypoglycemia. This unfortunately can be common in yorkies, especially when young. They are a lively breed and can use a lot of energy playing for small stints, especially if outside in warm conditions. Purchase some Nutrical for puppies this helps with maintaining a healthy dose of vitamins daily. Also make sure your cutie-pie Korki gets water and eats well. If her appetite slacks, give her the Nutrical as a supplement or things like honey or syrup. Never let her go more than 6-8 hours without eating or replenishing after a good does of playtime. Right now at 1lb she simply can't make up the difference. If this reoccurs one too many times, I would have her checked by your vet for any type of bacteria infection that can wipe out her system even more.
But welcome again, I have found this forum to be an excellent source of information and a good way to stay in touch with fellow yorkie lovers
