Bilious vomiting syndrome should never have blood in it. I think Hazal needs to be checked out by a vet since there is blood in her vomit now. Blood can come from a bleeding or clotting disorder, ulceration of the esophagus or stomach, intestinal parasites, bacterial or viral infection, IBD, among a few other things. If she has not responded to treatment for bilious vomiting syndrome, your vet may want to treat her for less common intestinal parasites, H. pylori, IBD, food allergy, etc.

    Hello, sorry to hear about Hazal. There are several things that could be going on with her including inflammation of her stomach, esophagus, ulcers in the stomach, parasites, or even abnormal bacterial growth. Other diagnostics to consider include bloodwork, an abdominal ultrasound and potentially an endoscopic examination. If the signs continue, Hazal should definitely be evaluated by your veterinarian or specialist promptly. Hope this helps and best of luck.

    Hi and thank you for posting! If blood is in the vomit, this is a little worrisome. Blood in the vomit can be a sign of exposure to a toxin, a stomach ulcer, foreign body, organ dysfunction, or a clotting disorder. I would advise you visit your vet very soon to determine the cause. They may do bloodwork, take x-rays or an ultrasound and/or preform an endoscopy of her stomach. Treatment will depend on what the veterinarian determines as the cause. I hope this helps and thanks for posting on Petco Pet Education Center, formerly Petcoach!
