As long as the puppy is nursing, mom will produce milk and the amount will increase as the baby nurses. When you have a puppy that is walking a thin line like this one is, YOU need to have much more control on what is going on. I would suggest you immediately learn how to tube feed this puppy...there is a recipe for a formula that I have used on any of my babies that needed tube feedings....that formula gives you 14 - 16 calories/cc.....you feed 1cc/oz of body weight. You must weigh that baby at least twice a day, and monitor weight closely. Adjust your tube feedings accordingly...you WANT that baby to nurse if he will do so, so you have to balance tube feedings with the nursing....you dont want to fill him up so he is not hungry and does not need to nurse.....but you want him to be gaining weight. Even after you tube feed him, allow his momma to lick him....that is bonding with her baby. Have you ever had a newborn before or is this your first whelp? Keep that baby out of drafts....keep a heating pad on LOW, and I place my heating pads under the BOX that the babies and momma lay in....I do not want the possibility that a baby will come into direct contact with that heating pad....they will cook.....been there, done that. I also throw one of those heated throws, over the top of the crate momma and babies are in...the ambient temp inside that area should be around 85*, maybe a little more. With a husband that is a doctor, this is great! HE can teach you how to pass a feeding tube! Have him watch a video on YouTube and then he can teach you how to do it.....see one, do one, teach one! As long as the baby is gaining weight, and nursing, you may only need to tube feed 3x's a day....according to weight! Always tube feed FIRST, then allow the puppy to nurse in order to fill up.....that way, you wont overfeed and risk regurgitation/aspiration.
Good thing you are changing vets....
