I have a 2 week old puppy and I'm feeding him mothers replacement milk but some times it looks like he don't want it what should I do?

Babies eat what they want when they want. Keep the milk at the correct temperature and keep all the equipment clean. Sometimes when you pick him up to feed him he won't eat right away because he wants to wet first then he will have enough room in his stomach to eat. Also feed often small meals a large meal even if he seems to want it at the time could give him colic. Discard milk in the bottle if he doesn't drink it all after a few hours (of course put in refrigerator and rewarm it between times.) If for some reason he goes more than a few hours without eating or doesn't wet or have a bowel movement when he has eaten and rested call the vets' immediately you might have to give him antibiotics or intravenous glucose. Good luck.

What's up with Momma? Did she pass away or reject the puppy?
