Thank you for submitting your question. Diarrhea and the bloody urine are likely due to separate causes. Diarrhea can be the result of an intestinal infection, dietary indiscretion (eating something that upset her gastrointestinal tract), inflammation or even stress. Bloody urine is typically due to a bladder infection, bladder stones, a primary bleeding disorder or in rare cancers bladder cancer. She will need to see her veterinarian for urine and fecal testing as she will likely require medication to treat her issues. I hope this information helps!

    Oh dear! Extremely bloody diarrhea like this is very concerning. This is often caused by an illness called HGE (hemorrhagic gastroenteritis), but it could also be due to a bleeding disorder of some kind, a severe systemic illness like liver or kidney disease, or ingestion of something toxic. Regardless of the underlying cause, this is a medical emergency - dogs with these symptoms often become much sicker and die within hours without aggressive treatment including IV fluids, antibiotics, and medication to stop the diarrhea and/or vomiting. I would recommend taking your dog to the nearest emergency vet immediately.

    I'm glad that your dog is feeling better now. I'm not quite sure what your question is, so feel free to post again if there was something specific you wanted to know. Pooping liquid blood everywhere is a very concerning sign, and I would really recommend taking him to the vet right away even if he seems to be acting better. This can be caused by a serious GI problem like HGE (hemorrhagic gastroenteritis) or pancreatitis, ingestion of something toxic, or even parvo if your dog is young and not fully vaccinated. All of these are potentially life-threatening problems that require IV fluids and aggressive supportive care, so it would be best to take your dog to a vet today to be treated.

    The blood in his diarrhea could be due to irritation of the GI tract since he's had diarrhea for three days. As long as he is eating without vomiting, isn't lethargic, and is drinking water, you can wait until the morning to have him see a vet. Now if he starts vomiting, becomes lethargic, the amount of blood in his diarrhea increases, he stops eating, and/or he stops drinking, then I would take him into an ER vet. Best of luck, I hope this helps!
