My dog ate moldy food. Why is their stool green with white pieces?

Updated On September 23rd, 2025

I am pet sitting two pugs and their owner gave us their dog kibble. None of the dogs ate the food which made me wonder why and when they did eat it, it would be a little bit until I saw there was mold on the kibble (which explains the diarrhea). I bought new dog food and so far it's helped them. Their stool became soft to solid but now I'm seeing almost a green stool with white all around and they come out in small sizes now. What's going on? Am I doing something wrong?

You are doing good, unfortunately the moldy food might have caused a gastrointestinal infection already, and this will probably require an antibiotic treatment. contact the Owners and explain the situation, they should understand that their dogs need to see a vet.
