Hello, that sounds more consistent with potential parasites. Parvo may intially cause brown to dark red liquid diarrhea with occasional blood. However, the only true way to know is to test the stool for parvo with a parvo test. In addition to the diarrhea puppies will also have vomiting, lethargy, and decreased appetite. Your puppies are a bit too young to have parvo as they should still have their mothers immunity they received via the colostrum. If your puppies however did not nurse from mom, then they may be at risk for parvo. Hope this helps and best of luck.
