Thank you so much for all your suggestions/advices. I will definately try out the formula for hypoglycemia. KiKi has been on/off, and sleep a lot, too. He eat a little bit, and then stop. He shake like a chihuahua, this morning. Anyway, I saw him eat at the breeder's home (Eukanuba puppy food), and he was very playful. He was fine on our first day together. It went down-hill since. My observation is...When KiKi has no food in his stomach and he drink alot of water, he ended up sneezing up this clear slimmy stuff. He pee ok, not too much poop. I need a miracle.
