Is your dog throwing up yellow liquid? It can look scary, but it usually means your dog is vomiting bile. This often happens when their stomach is empty or upset.
Yellow vomit in dogs often means there’s bile in the stomach, usually from being empty for too long. Acid reflux, food allergies, or digestive issues like pancreatitis or blockages may also cause it. If it happens often, a vet check is recommended.
In this article, you’ll learn the common reasons why dogs throw up yellow, what it means, when to worry, and how to help your dog feel better at home.
What Is Yellow Bile in Dogs?
Yellow vomit typically indicates the presence of bile. Bile is a bitter, yellow-green liquid that helps break down food in the small intestine. If a dog vomits yellow bile, it usually means their stomach is empty and irritated, causing bile to backflow into the stomach.
Why Is My Dog Throwing Up Yellow?
Bilious Vomiting Syndrome
This is a common cause of yellow vomit in healthy dogs. It happens when bile irritates an empty stomach. Dogs with irregular feeding schedules are more prone to it.
Treatment tip: Feed small, frequent meals—especially late at night or early morning.
Gastrointestinal Diseases
Conditions like gastritis, inflammatory bowel disease (IBD), or ulcers can irritate the stomach and cause bile vomiting. Symptoms often include chronic vomiting, weight loss, or diarrhea.
Pancreatitis
Pancreatitis is the inflammation of the pancreas, often caused by eating fatty or inappropriate foods. It can result in yellow vomit, along with:
- Loss of appetite
- Abdominal pain
- Diarrhea
- Lethargy
This is a medical emergency and requires immediate veterinary care.
Addison’s Disease
Addison’s disease (hypoadrenocorticism) is a hormonal imbalance that affects the adrenal glands. Vomiting, especially yellow bile, is a common symptom, along with weakness, weight loss, dehydration, and low energy.
Intestinal Blockages
If your dog has eaten a toy, bone, or foreign object, it can cause a blockage. Vomiting yellow bile is one early sign. Other symptoms include:
- Loss of appetite
- Abdominal pain
- Constipation or diarrhea
Allergies
Food allergies or intolerances can irritate the stomach and lead to vomiting. Common triggers include chicken, beef, grains, and dairy.
What To Do If Your Dog Is Throwing Up Yellow
If your dog throws up yellow bile, let their stomach rest for a few hours. Offer fresh water slowly. Then give bland food like rice and chicken. Feed small meals regularly. If vomiting continues or your dog seems tired, weak, or stops eating, contact a veterinarian for a full checkup.
