Zaccheus is a wee little man

Yes, I said IS.
My sister's Yorkie had pups and he is not thriving. All but the runt are double his size, but, unlike the runt-girl, he will not suck. The vet thinks he may have a cleft palate.
He is so tiny she named him Zaccheus. Fitting because although he is so tiny, he is a fighter. She has tried to keep him alive the past five days, but without thriving, the vet says the most humane thing to do is put him down.
But I wanted to try to save him, so I went to pick him up after dinner. If he makes it through the night, it will be a miracle.
I will get up every hour or so and try to feed him. His digestive tract is working. He just cannot wrap his tongue around the bottle. I basically pour formula down his throat and try not to choke him to death.
I am carrying him around in a fleece pouch next to my heart once in a while to keep him warm and stimulated. Other than that, he sleeps in a plastic bin on top of a heating pad and lightly covered with a baby blanket.
If he lives I'll post some pictures.
It's gonna be a long night.
