It could be either. To start, I would call your vet now about stopping the Prednisone. Some dogs can be sensitive to the steroids and it could be causing damage to the stomach/intestines. I would recommend taking Puppy to the vet for evaluation if the diarrhea last longer than 24 hours, or sooner if there is vomiting or lethargy. Other causes of bloody diarrhea could include bacterial or viral infection, HGE, IBD, intestinal parasites, among others.
