Why are my 2-week-old nursing puppies' poop yellow, wet, and soft?

Updated On September 23rd, 2025

Pet's info: Dog | American Pit Bull Terrier | Male | 14 days old

HI, my puppies turned 2 weeks old today. They are nursing from their mom. The last couple of days, their poop changed from dark brown and firm to a yellow wet to soft serve consistency. It looks like breastfed human newborn poop. Besides the change in bms, they are normal. They eat with fantastic enthusiasm, are strong, crawl around, whine when they are hungry/need to go to the bathroom, twitch in their sleep. Mom is eating 6 cups Pedigree puppy with cottage cheese mixed in & 2 boiled eggs/day.

Hello, congratulations on your puppies. In general they can have waxing and waning stool consistencies when they are this young. Most common causes for stool changes in puppies include parasites, dietary indiscretions, or changes in their GI tracts as they develop. Currently they are too young to deworm, however, as long as they are continuing to eat then you may keep monitoring them for any lethargy, worsening soft stools or diarrhea, or parasites in their feces. If you note any of these then contact your veterinarian to have them evaluated sooner. Otherwise, continue to allow them to nurse and begin to offer wet puppy food at 4-6 weeks of age. Hope this helps and best of luck.
