Why are my 4-week-old puppies throwing up after nursing? Mom won't feed.

Updated On September 23rd, 2025

Pet's info: Dog | Blue Heeler | Female | unspayed

I have four week old puppies and after they feed on mama some will go and throw up white liquid looks like what they just ate. But then they will run and play and be Normal. They all are fully energetic and healthy looking. I don't want nothing to be wrong with them what shall I do. Mom doesn't want to feed them much anymore either. And when she does it's standing up. I have to tell her to lay down. Also I have checked her glands none swollen or discolored or anything.

If they are nursing standing up they may be throwing up because of that. If mom doesn't want to feed them anymore, I suggest you start transitioning them to solid foods. The best one would be this one from Royal Canin: https://www.chewy.com/royal-canin-starter-mousse-mother/dp/118070
