Hello. Thank you for using PetCoach. Sorry Aaron is having this issue. Your English was fine - no worries! I suspect the cause is worms. That is the number one reason for a puppy to have blood in the stool. It would be more helpful if we knew exactly where you were located so we could better help you. Those medications are not ones we use in the United States so I am guessing you don't live here. From what I can gather, at least one of those drugs he received is a dewormer but not all dewormers treat every type of possible parasite. My guess is that he may have whipworms and whipworms need a longer course of dewormer and not just one shot or pill. So, I suggest you speak to your vet about the possibility of whipworm infection and see if they can give you a longer treatment. That is all I can really tell you over the internet. Here is a link to an article about blood in the stool of dogs that may answer more of your questions. https://www.petplace.com/article/dogs/pet-health/blood-in-dogs-stool-hematochezia/ Hope this helps. Best wishes.
