Introduction
If you've ever witnessed your dog vomiting blood, it's natural to feel alarmed. Blood in a dog's vomit can be a sign of a serious underlying medical condition, or it can be a relatively minor issue. The key is to understand the potential causes and seek veterinary attention promptly to ensure your pet's well-being.
Potential Causes of Blood in Dogs' Vomit
Hemorrhagic Gastritis
Hemorrhagic gastritis is a condition in which the stomach lining becomes inflamed and bleeds. This can be caused by various factors, including:
- Ingestion of foreign objects
- Certain medications
- Bacterial infections
- Chemical burns
Esophageal Ulcers
Esophageal ulcers occur when the lining of the esophagus, the tube connecting the mouth to the stomach, becomes damaged. This can be caused by:
- Reflux of stomach acid
- Ingestion of corrosive substances
- certain medications
Coagulation Disorders
Coagulation disorders prevent the blood from clotting normally, leading to excessive bleeding. This can be caused by:
- Inherited conditions
- Liver disease
- Certain medications
Parasites
Internal parasites, such as hookworms and roundworms, can attach to the lining of the gastrointestinal tract and cause bleeding.
Trauma
Physical trauma, such as a fall or a blow to the abdomen, can damage the digestive system and cause vomiting of blood.

Symptoms of Blood in Dogs' Vomit
The appearance of blood in a dog's vomit can vary depending on the underlying cause:
Fresh Blood
Fresh, bright red blood in the vomit suggests recent bleeding in the upper digestive tract, such as the esophagus or stomach.
Dark Blood
Dark, coffee-ground-like vomit indicates that the blood has been in the digestive tract for a while and has been partially digested. This suggests bleeding in the lower digestive tract, such as the small or large intestine.
Accompanying Symptoms
Blood in a dog's vomit may be accompanied by other symptoms, such as:
- Vomiting multiple times
- Diarrhea
- Abdominal pain
- Lethargy
- Loss of appetite

- Blood tests
- Urinalysis
- Abdominal X-rays or ultrasound
- Endoscopy
Treatment for blood in dogs' vomit will depend on the underlying cause. Common treatments include:
Medications
Anti-nausea medications can help control vomiting. Antibiotics may be prescribed to treat infections.
