If your dog is farting more than usual and suddenly not eating, it could be more than just a tummy issue. While gas is normal, excessive flatulence combined with loss of appetite may signal digestive trouble, dietary intolerance, or a more serious underlying condition.
We outline the common causes of dog farting and not eating, what you can do at home, and when to seek veterinary help.
Dog Farting and Not Eating — Why It Happens
If your dog is farting and not eating, it can be a sign of digestive distress or a more serious underlying condition.
Gastrointestinal issues like food intolerance, dietary indiscretion, or even gastrointestinal obstructions can cause gas buildup and appetite loss.
More chronic concerns like pancreatitis, inflammatory bowel disease, or even liver disease may also contribute to these symptoms.
While some causes may be temporary and mild, others require urgent medical attention.
Common Causes of Dog Farting and Not Eating
Food Intolerance or Allergy
Certain ingredients in your dog’s food can cause an upset stomach and excessive gas.
Dogs with food allergies or sensitivities may experience bloating, flatulence, and a reduced appetite. Ingredients like dairy, wheat, soy, or even certain proteins (like beef or chicken) can irritate the gut.
You might also notice other symptoms like itching, vomiting, or diarrhea.
If left unchecked, chronic exposure to irritating foods can lead to more serious digestive inflammation.
Dietary Indiscretion
Dogs are notorious for eating things they shouldn’t.
If your pup got into the trash, ate spoiled food, or snuck a fatty table scrap, their digestive system might be paying the price. Excessive gas and refusal to eat often follow dietary indiscretion.
This can also lead to vomiting, diarrhea, and abdominal pain.
In mild cases, symptoms improve in 24–48 hours, but if not, a vet check is necessary.

Pancreatitis
Pancreatitis is the inflammation of the pancreas, often triggered by fatty foods or certain medications.
It disrupts normal digestion and causes symptoms like nausea, bloating, gas, and loss of appetite. You may also see vomiting, lethargy, and hunched posture from abdominal pain.
This condition can range from mild to life-threatening and needs immediate veterinary care.
Intestinal Parasites
Parasites like roundworms, hookworms, or giardia can cause gastrointestinal symptoms.
Infected dogs may experience gas, bloating, diarrhea, vomiting, and appetite loss. Puppies and dogs with weakened immune systems are especially vulnerable.
Routine fecal exams and deworming can help catch and treat these infections early.
Inflammatory Bowel Disease (IBD)
IBD is a chronic condition where the intestines become inflamed and sensitive to food.
It often presents with chronic or recurring symptoms: flatulence, vomiting, diarrhea, and a decrease in appetite. Dogs may also lose weight and become lethargic.
IBD is typically diagnosed via biopsy and managed with diet changes and medication.
Gastrointestinal Obstruction
A more serious concern is a blockage in the digestive tract.
If your dog swallowed a foreign object (toy, sock, bone), it can cause gas to accumulate and prevent food from moving through the gut.
Signs include vomiting, restlessness, severe lethargy, and no appetite. This is an emergency requiring immediate surgery.
What to Do If Your Dog Is Farting and Not Eating
Start by reviewing your dog’s recent diet. Have they eaten something unusual or new? If a dietary change is suspected, remove the new food and revert to a bland diet of boiled chicken and rice for 24–48 hours.
Encourage hydration by offering fresh water and adding water or low-sodium broth to food. If they continue to refuse food, avoid forcing them to eat, as this can worsen nausea.
You can also walk your dog gently to help release trapped gas, but only if they’re not in visible pain. Avoid giving human medications or over-the-counter remedies without veterinary approval.
If symptoms persist more than 24 hours or worsen, it’s time to call the vet.
When to Call or Visit Your Vet
If your dog is experiencing any of the following, seek prompt veterinary attention:
Vomiting multiple times or vomiting with blood
Severe bloating or a hard, distended abdomen
Lethargy or weakness that worsens
No appetite for more than 24 hours
Signs of pain (whining, restlessness, hunched posture)
Straining to defecate or signs of constipation
Suspected ingestion of foreign objects
Early intervention can prevent complications and speed up recovery.

Key Takeaway
If your dog is farting and not eating, it could be anything from a mild stomach upset to a serious gastrointestinal issue.

Your attentiveness can make all the difference in helping your pup recover comfortably and safely.
