Why do my newborn puppies have diarrhea after mom took antibiotics?

Updated On September 23rd, 2025

Pet's info: Dog | Great Dane | Female | unspayed | 1 year old

Lola's puppies are 9 days old. They started having loose yellow seedy stool two days ago. They're pooping everywhere without stimulation from Lola. Lola has been on three antibiotics since the puppies were 2 days old. Could this be the upset? They're eating and gaining weight. I gave puppies and Lola plain Greek yogurt yesterday and today the poop is more like toothpaste consistency.

I'm sorry to hear Lola's pups have diarrhea. Without knowing what antibiotics Lola is taking and why, it is possible that the antibiotics Lola is taking have caused the diarrhea in the pups. The improvement in the diarrhea is likely due to the probiotics, or beneficial bacteria, in the Greek yogurt. You may want to consider adding in a veterinary probiotic supplement that is formulated for dogs and puppies. I would also recommend consulting with your veterinarian regarding the diarrhea. Diarrhea in puppies can become very serious very quickly. There are other causes for diarrhea in puppies as well, such as parasites and viral infections, which may require further treatment from your veterinarian. Your veterinarian will likely recommend performing fecal tests to rule out some of these other potential causes.
