Hi there and thanks for posting!

Blood in the stool and vomiting can have a variety of causes such as parasites, viral, or bacterial infections. Anal gland infections or cancer near the colon or of the large intestines can also cause blood in the stool. Gastrointestinal obstructions can also cause loose stool and vomiting.

My best advice is to withhold food from Fandanggo until tomorrow morning (he can have water, however). Tomorrow morning, feed him small amounts of boiled chicken, rice, and plain canned pumpkin ( not he pie filling). If he is still vomiting and having diarrhea today or tomorrow, he really should see a veterinarian as soon as possible. As mentioned above, there can be many causes for Fandanggo's symptoms, so it is best if not too much time goes by without seeing a veterinarian.

I hope this helps and thank you for posting on Petco Pet Education Center, formerly Petcoach!

    Unfortunately the cause of Ben's illness may require a vet as it could potentially be something serious. You can try feeding him small amounts of boiled chicken and white rice a few times a day. You can add extra water to it to increase his hydration. You can also give him a probiotic and a dewormer which can help. However there is a chance these symptoms could be caused by something serious like a virus, intestinal blockage or pancreatitis, all of which require hospitalization and significant care or even surgery. If he is not better within 48 hours, try to find a way to take him to the vet. I hope Ben starts feeling better!
