Why is my dog vomiting blood on an empty stomach? Is it serious?

If it was the one episode of vomiting and he is otherwise acting normally then I would be concerned but not panicked. I would watch him for the next 24 hours to see what happens. If there is more vomiting or bloody diarrhea then i would get him checked right away. It may be from having an empty stomach or eating something he was. It suppose to

Poor Lily. Vomiting streaks of blood is a medical emergency ,and she could have a foreign body, damage to her stomach or esophagus, GI ulcers, or may have eaten something toxic. You need to take her into a vet immediately.

This is a medical emergency, and Rosie needs to see a vet now. It is very serious when a dog throws up blood. She could have eaten something toxic, may have GI ulcers, could have a foreign body, or could have suffered trauma to her GI tract. She requires veterinary attention now to diagnose what is causing her to vomit blood so she can be treated. Please take her into a vet now.

Yes, I would be concerned. Vomiting blood is serious, and if Lola's eaten something sharp, it could be piercing her stomach and/or intestines causing the blood in her vomit. In addition, you are correct that it could bet stuck in her stomach. I would take Lola into see a vet immediately.

Poor Lady! Eating tissue paper should not normally cause any significant issues unless she ate a very large amount, so this is probably not related. Vomiting blood is always a very serious concern, so I would recommend taking Lady to the vet right away for an exam. She may have internal bleeding due to a stomach ulcer or foreign body, a GI illness such as pancreatitis or HGE (hemorrhagic gastroenteritis), or may have gotten into something toxic. Your vet can do blood work and x-rays if needed to help diagnose the problem and get her started on appropriate treatment right away.

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!
