Severe Liver Disease

It’s essential to act fast if your pup is vomiting up red liquid – seek a vet right away! This is especially true if the vomiting is accompanied by other symptoms like lethargy, lack of appetite, or diarrhea. While there are many potential causes of vomiting blood, one of the most serious is liver disease. Liver disease can cause a wide range of symptoms, from mild to life-threatening.

Intestinal Parasite

If your pup is vomiting up blood, it may be a sign that they have an intestinal parasite. These little critters can cause irritation to the intestines, leading them to expel stomach contents with red in tow – seeing as this isn’t normal for canine digestion, take your four-legged friend immediately to the vet! In some cases where these parasites migrate further upwards into their internal organs like their esophagus and stomachs could also lead to bloody vomit scenarios – time is of utmost importance here!

There are a few different types of intestinal parasites that can cause this problem, so your vet will need to run some tests to determine which one is present. Treatment will vary depending on the type of parasite, but may include oral or injectable medications. Prevention is the best way to keep your dog from getting these parasites, so be sure to use a monthly preventative and keep them up to date on their vaccinations.

Blood Clotting Problems

If you’re asking “why is my dog throwing up blood?”, there are several blood clotting issues that may be the cause. There are several conditions that can cause problems with blood clotting in dogs, including:

Von Willebrand’s Disease

Von Willebrand’s disease is a common inherited disorder that can cause excessive bleeding in dogs. The disease is caused by a deficiency of von Willebrand factor, a protein needed for blood clotting. Von Willebrand’s disease is seen in many different breeds of dogs, but is most common in Doberman Pinschers, German Shepherds, Golden Retrievers, and Poodles.

The most common symptom of von Willebrand’s disease is excessive bleeding from minor cuts or injuries. Dogs with the disease may also have bloody diarrhea or vomiting, and prolonged bleeding after surgery.


Thrombocytopenia is a condition characterized by low levels of platelets in the blood. Platelets are important cells that help to clot blood and stop bleeding. When there are not enough platelets present, excessive bleeding can occur. Thrombocytopenia can be caused by many different things, including certain medications, viruses, and autoimmune diseases.
