Half-month-old puppy just opened eyes and keeps having diarrhea, what to do?

A newborn puppy with constant diarrhea may be due to high fat in the milk, a chill, or overeating. Note that yellowish soft stool is normal because mother’s milk is liquid and waste is high in water; feed the mother reasonably and avoid greasy food.

But watery diarrhea may signal digestive trouble, such as a chill — puppies are weak and easily catch cold, so keep their environment warm.

Puppies don’t feel full and overeating causes indigestion diarrhea; reduce feeding appropriately to see improvement.
