Causes of Dog Vomiting Blood

A dog vomiting blood can be a distressing sight for any pet owner. Understanding the potential causes is crucial for early detection and effective treatment. Here are some common reasons your dog might be experiencing this alarming symptom:

Gastrointestinal Issues

Gastrointestinal problems are a leading cause of blood in a dog’s vomit. Conditions like gastritis, ulcers, or inflammatory bowel disease can irritate the stomach lining, leading to bleeding. If your dog has a history of digestive issues or has recently ingested something harmful, consult with our veterinarians immediately.

Ingestion of Foreign Objects

Dogs are curious creatures, and sometimes their curiosity can lead to trouble. Swallowing foreign objects, such as toys or bones, can cause internal injuries and bleeding. If you suspect your dog has swallowed something they shouldn’t have, seek veterinary care promptly.

Canine Parvovirus

Parvovirus is a highly contagious and dangerous disease that can cause severe gastrointestinal distress, including bloody vomiting. Vaccination is the best prevention, but if your dog exhibits symptoms like vomiting blood, lethargy, and diarrhea, contact us urgently.

Emergency Actions

If you ever find your furry friend vomiting blood, it’s crucial to take immediate action while seeking professional help. Here are some steps you can take:

  • Stay Calm: First and foremost, remain as calm as possible. Your dog can sense your anxiety, which may exacerbate their distress. Stay composed to provide them with the best care.
  • Contact West Loop Veterinary Care: Reach out to us at West Loop Veterinary Care at either of our locations. Our experienced veterinarians will guide you through the next steps and provide the necessary care.
  • Monitor Your Dog: While awaiting veterinary assistance, keep a close eye on your dog’s condition. Note any changes in their behavior, such as increased lethargy, weakness, or more severe bleeding.

Treatment for Dog Vomiting Blood

Once you’ve contacted us and your dog is in our care, our team will determine the appropriate treatment plan based on the underlying cause. Here are some common treatments:

Fluid Therapy

In cases of severe blood loss, intravenous (IV) fluid therapy may be necessary to stabilize your dog’s condition and prevent dehydration.


Depending on the cause of the bleeding, your dog may require medications such as antacids, antibiotics, or anti-inflammatory drugs to address the issue.

Surgical Intervention

In cases of foreign object ingestion or other serious conditions, surgery may be necessary to remove the offending item or treat the underlying problem.
