Do you mean really runny poop? If he has watery diarrhea, I would strongly recommend to have a vet look at him. Being so young and small, he could easily get dehydrated despite drinking water. Diarrhea can be from several things like parasites, a change in diet, viral infections like parvo, toxins and much more. You can try to feed him some plain boiled boneless skinless chicken and white rice to see if this settles his tummy. If he isn’t improving, I would have your vet take a look at him. I hope this helps and he starts to feel better!
