What is Vomiting of Blood?

Vomiting of blood, called hematemesis, is a fairly common symptom in dogs that can be associated with a number of different diseases. Vomited blood is easily recognizable when it is fresh, but if it is partially digested it often has a dark grainy appearance, similar to old coffee grounds. Any problem that erodes the lining of the stomach can expose arteries and cause gastrointestinal hemorrhage that will make your dog vomit blood. Ulcers, gastritis or drugs like NSAID’s are common reasons. Tumors located in the stomach or esophagus can also cause this problem, as well as infections like coronavirus and parvovirus. Less obvious sources are liver or kidney disease, shock, internal trauma that bleeds into the stomach, and diseases that affect blood coagulation. Hematemesis should be distinguished from coughing of blood (hemoptysis), which is due to a respiratory problem, although occasionally dogs may swallow blood from a respiratory tract disorder and vomit it up in a similar way to hematemesis. Sometimes sores on the mouth or dental problems with bleeding are also mistaken if the source of the blood is not obvious. Hematemesis is a nonspecific symptom, but it can be a sign of serious disease.

Dogs may vomit blood for a variety of reasons. Veterinarians call this hematemesis. Depending on the amount of blood that is present, it can be associated with mild problems like stomach upset, or with serious life-threatening conditions.

Diagnosis of Vomiting of Blood in Dogs

Hematemesis is not a diagnosis in itself, but is an important symptom that will help the veterinarian identify your dog’s condition. You will need to give a complete medical history; medications like NSAID’s or corticosteroids can be especially important. Recent vaccination, exposure to poisoning, or potential trauma that could cause internal bleeding or shock are also relevant. A good description of your dog’s symptoms, including how much blood is present and whether the problem is acute or chronic, will help to eliminate some possibilities. Other symptoms like fever, diarrhea, or signs of shock can indicate what might be wrong with your dog.

Depending on the severity of the condition, blood tests will usually be taken to check for anemia, clotting disorders, or high levels of white blood cells from infection. This can also help to diagnose liver and kidney disease as well as paraneoplastic syndromes from cancer. Urine analysis can further evaluate many of these conditions. Ultrasound or x-rays may be necessary to check for cancerous tumors or internal injuries.

Treatment of Vomiting of Blood in Dogs

Dogs that are very ill and have lost a lot of blood may need immediate blood or plasma transfusions. Intravenous fluids and electrolytes will treat shock and balance dehydration from vomiting. Severe forms of gastritis, especially hemorrhagic gastroenteritis, can be life-threatening if they are not treated immediately. Viral infections like parvovirus and coronavirus will need to be managed symptomatically in this fashion also. Antibiotics may be given to eliminate vomiting caused by bacterial infection.

If the problem is related to chronic gastritis or ulcers, the veterinarian will treat your dog with antacids and antiemetics. Further treatments may then focus on eliminating the source of these diseases. Dogs may need to be treated for an autoimmune problem or follow a strict diet to avoid allergens. Activated charcoal may be given for drug overdoses or poisoning. Other medications may focus on eliminating parasites as well as treating liver or kidney disease. NSAID’s will be discontinued. Dogs with cancerous tumors, foreign objects, or internal injury may need surgery. In the case of an injury, emergency surgery could be required. For cancer, chemotherapy may be recommended post-surgery, or in the case of inoperable tumors.

Recovery of Vomiting of Blood in Dogs

The veterinarian will evaluate your dog’s chance of recovery upon diagnosis. Many conditions, especially those with only a small amount of blood can be treated easily and your dog will make a full recovery. Some conditions, like cancer, or liver and kidney disease, may require long-term management. Others can be immediately life threatening. Effective treatment will depend on the severity of your dog’s condition and the promptness of medical treatment.

Thank you for your question. She may not be feeling well if you are noticing vomit and she doesn't feel like eating. If this continues for any length of time, it would probably be best to have her seen by your veterinarian. They will be able to examine her, see what might be going on and get medication if she needs it. I hope that she feels better soon.

Hello, Many medications that we use in Vet Medicine are not FDA approved for dogs but approved for use in people. This is a medication that I have used many times on thousands of dogs for bloody vomit or diarrhea without any side effects. I hope your baby starts to feel better soon.

Blood In Vomit

My pup has been confined last August 10 because of parvo. I took him home August 13 but he still has his dextrose on. After an hour when we got home, he vomited a watery, dark red colored with brown powder like and little solids in it maybe the sized of red pepper seeds. I’m really worried. Is it because of the medications? Or is it because of his empty stomach that it got irritated or something or is it much worse than that?

It is possible that Zeno vomited due to an empty stomach coupled with the nausea from a car journey, however you should inform your Veterinarian about the vomiting of blood (simple phone call) and ensure that Zeno is hydrated and not showing any other symptoms. Regards Dr Callum Turner DVM

My dog had a kennel cough vaccine yesterday and today she went to daycare. Hours after dinner she threw up. Now she woke up from a sound sleep to throw up. Very little cake up but there was specks of blood in her throw up. Should I be concerned? Should I bring her to the animal hospital?

A speak or two of blood is concerning but not worthy of an immediate emergency unless there are other symptoms which may indicate poisoning or other concerning symptoms. Keep an eye on Sophie and ensure she is hydrated, after a few hours give small regular portions of boiled chicken and rice but if the vomiting continues, she develops a fever or any other symptoms visit your Veterinarian.

We took our dogs hiking. When we finished the trail our daughter fed them dog food. About 30 minutes later River started vomiting, she vomited 5 times in an hour and then stopped. About an hour after we got home she started vomiting again but this time it is bright red. She's vomited 10 times now, bright red and foamy. Her breathing hasnt changed, her stomach isn't hard and no guarding, she is behaving like normal minus the vomiting. Any ideas on the best source of treatment???

You should give River’s stomach a bit of a rest and after a few hours offer her some water, if she keeps the water down you should then offer her a small portion of boiled chicken and rice to see if she can keep that down too; if successful you should feed small regular portions of boiled chicken and rice, after a day or so start to wean her over to her regular food. There are many possible causes for vomiting blood, but if there is a large quantity of blood, you suspect she may have consumed something or there is no improvement you should visit your Veterinarian to be on the safe side.

My dog has thrown up multiple times throughout the night. Each time it was a clear foaming vomit. After throwing up all night we woke up to two piles of blood. She has not had a change in her diet nor has she eaten anything out of the ordinary of my knowledge. Should we take her in or wait it out a little bit?

My dog Jax has always puked up white foam, especially in the mornings or when he hasnt eaten much. The vet told us it was acid reflux. Usually, we give him a piece of bread and it "fixes" it bc it soaks up the stomach acid. However, this morning he starting pUsing foam again, but this time there was some bright red blood it. Lately hes been trying to eat grass, so I dont know if it's just his stomach being upset, or if its worms, or something worse. He hasnt acted lethargic lately, and hes been eating and drinking just fine. I am just worried that he needs immediate medical care, and it's a weekend so we are unable to get into a veterinarian.

Heart Murmur.
Heart Murmur. Bleeding From Mouth

My 12 year old chihuahua was found sitting on the couch this morning with some blood around her mouth and what looked like a small clot hanging from her mouth. We realized there was blood on the sheets from early morning and the blanket from this episode. We washed it and she seemed fine. Still presenting healthy in all other ways. Still walking around normally, nothing seems out of the ordinary at all. After eating a small piece of jerky we realized there was fresh blood on the bed again. Didn’t notice her throw up maybe more of like spit up. She doesn’t show to be throwing up or in any pain aside from when we tried looking in her mouth she’s not happy and whines a bit. It’s bright red blood like you’d see from a cut but coming from her mouth. Again, it happens without us even recognizing it’s happening so we think it may be in her mouth or teeth as she has really bad teeth and if only happened after eating something a little harder. Is this cause for alarm?

Diarrhea, Vomiting

I did not notice we were running low on my dogs hard kibble food, so while waiting for it to come (it is ordered online), I bought her some canned soft food. I fed it to her twice and noticed her stomach seemed upset (downward dog pose) but she seemed alert and happy and hungry. I took her out and she had diarrhea (not bloody). I got the kibble in the mail and fed it to her for dinner (still doing downward dog pose), and in the morning she threw up a few times (her food from the night before) and one little pile had what looked like tiny blood clots, but only one pile, the others were clear and spit like. She is drinking water but not currently eating as of this morning. Does this seem like just a reaction to changing her diet so abruptly? She hasn't pooped since her one time diarrhea episode yesterday.
