Dogs can sometimes show worrying symptoms like vomiting bile combined with loud stomach noises.
While an occasional upset stomach might not be alarming, these symptoms together can point to digestive issues that you shouldn’t ignore.
We outline the common causes of a dog throwing up bile and making stomach noises, what you can do at home, and when to seek veterinary help.
Dog Throwing Up Bile and Stomach Noises — Why It Happens
A dog throwing up bile while also having stomach noises often points to digestive upset, hunger-related irritation, or underlying illness. Bile is a digestive fluid that leaks into the stomach when it’s empty, irritating the lining and leading to yellow or green vomit.
The gurgling or rumbling noises, known as borborygmi, usually occur when gas or fluids move through the intestines. Together, these signs may be linked to an empty stomach, dietary sensitivity, intestinal parasites, pancreatitis, or more serious gastrointestinal disease.
The context and frequency of these symptoms are important for understanding whether it’s a minor issue or a sign of something requiring veterinary care.
Dog Throwing Up Bile and Having Stomach Noises: Common Causes
Empty Stomach and Hunger Pains
When a dog goes too long without food, bile can build up in the stomach and cause irritation. This often leads to vomiting a yellowish fluid, usually early in the morning or late at night.
Alongside this, the stomach and intestines may make loud gurgling noises because they’re empty and gas is moving through them.
Dogs that are on one meal a day or miss meals may be especially prone to this. While occasional hunger-related bile vomiting isn’t always dangerous, if it happens frequently it can cause discomfort, weight loss, and other complications.

Dietary Indiscretion or Food Sensitivities
Dogs that eat something unusual — such as table scraps, garbage, or spoiled food — can develop stomach upset.
This irritation can lead to vomiting bile as the digestive system tries to clear the irritant. Stomach noises often increase because of excess gas production, diarrhea, or poor digestion of the unusual food.
Food allergies or sensitivities can also cause chronic digestive problems, with ongoing rumbling, bile vomiting, or soft stools. You may notice patterns, such as symptoms worsening after eating certain proteins or treats.
Intestinal Parasites
Parasites such as roundworms, hookworms, or giardia can interfere with normal digestion.
They may irritate the stomach and intestines, leading to vomiting bile, gurgling stomach noises, diarrhea, and weight loss.
Puppies and dogs without regular deworming are at higher risk. Stomach noises become more noticeable as parasites disrupt the gut lining, causing excessive gas and fluid movement. Left untreated, parasitic infections can become serious and even life-threatening.
Pancreatitis
Pancreatitis is inflammation of the pancreas, often triggered by eating fatty foods. Dogs with pancreatitis may vomit bile repeatedly, act lethargic, refuse food, and have painful abdomens.
Their stomachs may also produce loud noises due to digestive upset and inflammation. Unlike occasional hunger-related bile vomiting, pancreatitis is a medical emergency that requires veterinary care.
Signs such as hunched posture, shaking, diarrhea, and dehydration often accompany the vomiting and gurgling.
Gastrointestinal Obstruction
If a dog swallows a foreign object like a toy, bone, or sock, it can block the digestive tract. This can lead to repeated bile vomiting since food and fluid cannot move properly through the intestines.
Stomach noises may initially be loud but often decrease if the obstruction stops movement entirely.
Other signs include restlessness, drooling, abdominal pain, and loss of appetite. Obstructions are extremely serious and can be fatal without surgery or urgent veterinary treatment.
Inflammatory Bowel Disease (IBD)
Some dogs develop chronic inflammation of the intestinal lining, known as IBD. This condition can cause ongoing bile vomiting, loud digestive noises, diarrhea, and weight loss.
The immune system mistakenly attacks the gut, disrupting normal absorption and digestion. Symptoms may wax and wane, but they typically worsen over time without management.
Dogs with IBD often require special diets and long-term veterinary care to control flare-ups and improve quality of life.
What to Do If Your Dog Is Throwing Up Bile and Having Stomach Noises
If your dog occasionally vomits bile with stomach gurgling but otherwise seems healthy, you can start with small at-home steps. Feeding smaller, more frequent meals can help prevent the stomach from staying empty too long, reducing bile irritation.
Offering a bland diet of boiled chicken and rice for a day or two may also soothe the digestive system.
Make sure your dog always has access to fresh water to prevent dehydration, especially after vomiting.
If food sensitivities are suspected, try keeping a food diary and switching to a limited-ingredient or hypoallergenic diet under veterinary guidance. Regular deworming and keeping your dog away from garbage or unsafe foods can prevent some of the most common triggers.
However, if symptoms are frequent or severe, at-home care is not enough and veterinary evaluation is needed.
When to Call or Visit Your Vet
You should contact your vet if your dog’s bile vomiting and stomach noises happen regularly, especially if more than once a week.
Immediate veterinary care is needed if you notice additional symptoms like lethargy, loss of appetite, diarrhea, or abdominal pain.
Signs such as blood in the vomit, continuous retching without producing vomit, or signs of dehydration like sunken eyes and weakness are emergencies.
If your dog has eaten something they shouldn’t, such as bones, toys, or fabric, seek help right away. Obstructions and pancreatitis both require urgent intervention and cannot be treated at home.
Even if symptoms seem mild, persistent bile vomiting with gurgling may signal an underlying condition that only a veterinarian can diagnose and manage.

Key Takeaway
A dog throwing up bile and making stomach noises is often linked to digestive upset from an empty stomach or dietary issues, but it can also be a sign of serious problems like pancreatitis or intestinal obstruction.
Occasional mild episodes may be managed at home with meal adjustments and careful monitoring, but frequent or severe cases require veterinary care.
Trust your instincts — if your dog seems unwell, uncomfortable, or the symptoms keep returning, contacting your vet is always the safest step.
