My dog keeps throwing up blood monthly. What's the real issue?

That does sound concerning. It is possible that she is having another flare up of her previous ulcers. Other causes for diarrhea and vomiting with blood in it include Addison's disease, intestinal parasites, tick-borne diseases, IMHA, IBD, intestinal cancer, among many others. I would recommend that Gubbu get checked out by a vet as soon as possible. After physical examination and a review of her medical history, the vet may recommend bloodwork to check for anemia and other relevant things. They may also recommend an abdominal ultrasound, which will help use get a picture of what her digestive tract is doing and looks like.

Vomiting blood is serious. The GI upset could be due to many conditions including eating something she shouldn't have, bacterial over growth, parasites (worms and giardia), poison, a bleeding disorder, pancreatitis, cancer or intestinal blockage. I recommend to have your pup examined by the veterinarian today. Try to remember to take in a stool sample. The doctor will check her for parasites and bacterial over growth and other diagnostics may be recommended as well. She needs the correct diagnosis in order to receive appropriate care. She also needs medications and possible fluids. I hope Coco starts feeling better quickly! Please feel free to post any additional questions!

Poor Shelby! Such chronic vomiting with lack ignorance appetite is definitely cause for concern. This may be caused by a stomach ulcer, foreign body, or parasites. I recommend having Shelby seen by a vet right away to determine what is going on and provide the appropriate treatment, which may include fluids, antibiotics, and hospitalization. I hope all is well and thank you for using Petco Pet Education Center, formerly Petcoach!

Blood in the vomit is definitely cause for concern, as it can indicate stomach ulcers, stomach parasites, or even a foreign body. As puppies are prone to getting into things they shouldn't, Simba may have ingested a toxin such as human pain medication or a piece of a toy. It is concerning that Simba did not feel well after vomiting. I recommend having him seen by a vet as vomiting blood can be a sign of a serious underlying condition. Your vet can perform bloodwork and x-rays to rule out the conditions above.

Cindy could have an infection, parasite, gastritis from something she ate, pancreatitis, ulcer, metabolic/endocrine disease. You could withhold food for the day and then try a bland diet, like chicken and white rice and see if that helps. If the vomiting continues or she becomes lethargic than she needs to be examined by a vet for treatment. Your vet can run lab-work and take x-rays, if needed, to help diagnose and then prescribe medications to help treat her problem. Hope she feels better soon.

Poor Hades. Vomiting up small amounts of blood could be a sign that he has a stomach ulcer. The severity of the ulcer can vary depending on how deep it is. I would recommend at least having him checked by your veterinarian and given some medications to help coat his stomach and intestinal lining to give things time to heal properly. He also may need to go on a short course of antacids to reduce the acid load for a while to allow things to heal well.

It sounds as Walter is suffering from a gastrointestinal condition, possibly an infection. it could also be due to ingestion of a foreign body material. i would recommend taking him to the vet the first chance you get, he will need to be checked first, if the vet thinks it's a simple gastrointestinal infection he will need an anti vomiting injection, antibiotics and a special food for a few days in order to get better.
