Why Is My Dog’s Stomach Making Noises? A Vet’s Guide to “Borborygmi”
Stomach noises in dogs, medically known as borborygmi, are usually caused by the normal movement of gas and fluid during digestion or simple hunger. However, if these loud gurgles are accompanied by vomiting, lethargy, or a “hunched” posture, they can signal a serious issue like an intestinal blockage or pancreatitis. If your dog is acting fine, it’s likely just gas; if they look sick, call the vet.
Key Takeaways
-
The Fancy Term: Those loud rumblings are called borborygmi (bor-bor-ig-my).
-
The “Echo Chamber”: An empty stomach is louder than a full one. Hunger is the #1 cause.
-
The Danger Zone: Loud noises + vomiting + pain = Veterinary Emergency (possible obstruction).
-
Quick Fix: Slow-feeder bowls reduce the amount of air your dog swallows, quieting the gut.
The Vet’s Take: When Your Dog Sounds Like a Washing Machine
I’ll never forget the night I woke up thinking my plumbing had burst. I sat up, looked around, and realized the noise was coming from under the duvet. It was Max, my Beagle-Lab mix. His stomach was making sounds that can only be described as a “whale song.”
Max, being a classic “garbage gut,” had found a forgotten piece of cheese during our walk. He was fine—just gassy—but the noise was alarming. In my clinic, panic over stomach noises is common. I always tell my clients: “Treat the patient, not the noise.”
If your dog is playing, eating, and wagging their tail, that noise is just the soundtrack of digestion. But if they are looking at their flank, whining, or refusing food, that sound is a distress signal.
The Science: What is “Borborygmi”?
Borborygmi is the sound of gas bubbles popping and fluid sloshing as intestines contract (peristalsis) to push food through.
Think of your dog’s intestines like a long, soft pipe.
-
When it’s full: The food muffles the sound.
-
When it’s empty: It acts like an echo chamber. The gas has nowhere to hide, so every gurgle is amplified.
This is why the morning—before breakfast—is prime time for the “tummy symphony.”
Why Is It Happening? (The Usual Suspects)
1. The “Empty Tank” (Hunger)
This is the most common cause. When the stomach has been empty for a while, the body releases hormones to prep for the next meal, triggering movement in the intestines. If you only feed once a day, you might hear this often.
2. Dietary Indiscretion (The “Oops” Factor)
Did your dog get into the trash? Did you switch kibble brands cold turkey? Sudden changes disrupt the gut microbiome. The bacteria in the gut go into overdrive trying to ferment the new food (especially carbs or high-fiber veggies), producing massive amounts of gas.
3. Aerophagia (Gulping Air)
If your dog eats like they’ve never seen food before (looking at you, Labradors), they are swallowing air along with their kibble. That air has to go somewhere. It usually exits as a burp, a toot, or a loud gurgle.
4. The Scary Stuff: Obstruction & Bloat
This is where we get serious. If your dog swallowed a sock, a rock, or a corn cob, the intestines will contract violently trying to push the object through. This creates very loud, high-pitched “tinkling” or “rushing” sounds.
-
Bloat (GDV): In this life-threatening condition, the stomach twists. You typically won’t hear gurgling; you’ll see a swollen, hard belly and a dog trying to vomit with nothing coming out.

5 Vet-Approved Ways to Quiet the Storm
If your dog is healthy but noisy, here is how to settle their stomach.
1. The “Slow Down” Strategy
Use a slow-feeder bowl or a puzzle toy. I cannot stress this enough. By forcing your dog to pick out kibble piece by piece, you stop them from gulping air. It’s the cheapest, most effective fix for gas.
2. The “Snack” Bridge
If the noises happen mostly in the early morning, your dog has “bilious vomiting syndrome” (hunger pukes).
-
The Fix: Give a small handful of kibble right before bed. This keeps the stomach working quietly overnight.
3. Hydration Check
Dehydration slows down the gut (motility), making gas pockets trapped and louder. Ensure fresh water is always available.
4. The “Gentle” Walk
Take a slow walk after eating.
-
Warning: Do NOT let them run or play fetch immediately after eating (this increases Bloat risk). Just a gentle stroll helps gas move through the system naturally.
5. Probiotics
If your dog has a sensitive stomach, a veterinary-approved probiotic can help balance the gut flora, reducing the gas produced during digestion.
Frequently Asked Questions
Q: Can worms cause stomach noises? A: Yes. A heavy load of roundworms or hookworms can disrupt digestion and cause gas. If you hear noises and see a pot-belly on a puppy, they likely need deworming.
Q: My dog’s stomach is making noises and he won’t eat. What do I do? A: This is a specific symptom combo that worries me. Anorexia + Gurgling often implies abdominal pain or nausea. Give it 12 hours (if they are adult and healthy otherwise); if they still won’t eat, see a vet.
Q: Can I give my dog Pepto-Bismol for the noise? A: Please don’t. While Pepto can sometimes be used under strict vet supervision, it contains salicylates (aspirin-like compounds) which can cause bleeding ulcers in dogs. Never medicate without calling your vet first.
