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.

    Your poor little pup! Sometimes when the flora (normal bacteria) of the gut gets disturbed by something like hook worms, the dog needs an antibiotic to help get the normal flora back into balance. I would call your vet and let them what is going on with the bloody stools and ask if they think he needs an antibiotic. I would continue the dewormer as prescribed to make sure all the parasites are taken care of. Good luck!

    Hello there and thank you for your post! With the history of intestinal parasites, it is likely that Nyx is experiencing a bout of colitis secondary to parasitic gastroenteritis. If Nyx is otherwise healthy and eating / drinking, I would monitor for the time being and get the 3rd treatment when it is due. If she becomes I'll and not doing well I would get her seen sooner rather than later. A bland diet of chicken and rice may do some good as well and feed this until the worms and stool issues have resolved. If you have any other questions or concerns please feel free to contact me.

    The bloody stool may be due to the parasites. Once he is dewormed, the stool should normalize. You can feed a bland diet and a veterinary probiotic to help recovery. Brands include FortiFlora, ProStora, ProViable or Bene-Bac. A repeat deworming may be indicated in 2 and 4 weeks.
