Sometimes throwing up blood can be due to a Doberman having a respiratory problem that results in coughing up blood which they swallow and then vomit. 

In other cases, a Doberman may also have a dental problem or mouth sores that bleed, which may be mistaken for throwing up blood.

Critically ill Dobermans are more susceptible to throwing up blood as well as puppies that have not yet had their parvovirus vaccination. 

Should I be worried if my Doberman is throwing up blood?

A Doberman throwing up blood at any point is a cause for concern because it is a clear sign of a serious underlying problem that requires immediate medical attention.

A Doberman throwing up blood should be treated as an emergency that requires a veterinarian to examine your dog.

When your Doberman vomits blood in whichever form, that is either little spots of blood, fresh or brown, small or large volume of blood, do not hesitate to contact your veterinarian.

The veterinarian will conduct a full physical examination, analyze your dog’s medical history, and ask you about the circumstances leading up to the vomiting.

This includes your Doberman’s recent intake of nonsteroidal anti-inflammatory drugs, vaccinations, other symptoms, evidence of ingestion of toxins around the home, or possible traumas that could have led to internal bleeding.

Also, various diagnostic tests will be conducted to uncover the underlying cause of the vomiting of blood.


A Doberman will first be given an anti-nausea medication to control and intravenous fluids to manage dehydration and shock from loss of electrolytes caused by the vomiting.

If the case is severe and your Doberman lost a lot of blood, they will be given a blood transfusion to treat anemia. They may be hospitalized for monitoring of their condition.

Infections will be treated, antacids will be provided if ulcers are present, the use of nonsteroidal anti-inflammatory drugs (NSAIDs) will be discontinued, and activated charcoal provided for possible poisoning.  

A bland diet consisting of boiled chicken and white rice will be recommended to help the stomach to calm down and heal.
