I worry about bloody diarrhea in puppies, because Parvo infections can start this way and quickly become life-threatening. It's good that she's acting normal at this time, but best to have her seen by a vet in the next 24 hours. They can help determine the severity of this and give the appropriate treatment. I hope that helps and Daisy gets better soon.

    Hi and thanks for using Petco Pet Education Center, formerly Petcoach! Sorry to hear about Bella. I would advise getting her re-evaluated or going to a different vet if you want a second opinion. This looks very serious and needs immediate treatment. Vomiting and diarrhea have many causes including intestinal worms, inflammation, infection, dietary problems (including dietary indiscretion or eating things pets are not supposed to eat, food sensitivities/allergies), ingestion of foreign bodies or exposure to toxins (rat poison), bacterial overgrowth in the gut, problems in the stomach, intestines, or even problems outside of the intestinal tract/stomach including pancreatitis, kidney/liver problems, metabolic disease (diabetes,etc), endocrine diseases (thyroid or other hormone problems), etc. A thorough history and physical exam with resultant diagnostics such as fecal tests, blood tests, imaging studies such as x-rays/ultrasound can be done to try to determine what is going on. Good luck with Bella.

    Hi, thanks for using Petco Pet Education Center, formerly Petcoach! Poor Osa! Since Osa is only 8 weeks old and is vomiting and having bloody diarrhea she needs to go to an Emergency hospital today. Puppies that young and only weighing 3 pounds are at an increased risk of dehydration and low blood sugar. Causes of bloody diarrhea and vomiting are: intestinal parasites, viral infections (including Parvo virus), bacterial infections, diet changes, food allergies/intolerance. I hope this helps and I wish Osa a speedy recover!

    Oh no, poor Cloudy sounds very ill! Thank you for letting me know she is vaccinated, it helps with my answer. She could be suffering from hemorrhagic gastroenteritis, may have a foreign body, could have have eaten something rotten or toxic, or could have a severe GI illness causing her symptoms. It's very concerning when a dog is having bloody feces while also vomiting, and in those cases, an immediate vet visit is always recommend. I advise to take her into a vet now to diagnose the cause of her symptoms so she can be treated. I hope this helps, and she feels better soon!
