You're sitting on the couch, finally relaxing after a long day, and then you hear it. That distinct, wet, rhythmic gulp-gulp-schlop sound. Every dog owner knows the panic that sets in when they realize their carpet is about to become a biohazard. But honestly, signs of upset stomach in dogs aren't always that obvious. It isn't just about the "presents" they leave on the rug. Sometimes, it's a subtle shift in how they carry themselves or a weird look in their eyes that tells the real story.
Dogs are stoic. Evolution taught them to hide pain so they wouldn't look like an easy snack for a predator. Because of that, your Labrador or Chihuahua isn't going to walk up and tell you they shouldn't have eaten that rogue piece of pepperoni. They’ll just act "off."
The Low-Key Red Flags You’re Probably Missing
Most of us wait for the big "V"—vomiting. But by the time a dog is actually throwing up, the stomach upset is already in full swing. One of the weirdest, most overlooked signs of upset stomach in dogs is excessive licking. I'm not talking about a quick paw clean. I mean they start licking the air, the floor, the walls, or their own lips incessantly.
Vets call this "ptyalism" or just plain old nausea. When a dog feels like they might toss their cookies, their mouth fills with excess saliva. They swallow constantly. They look frantic.
Another subtle one? Eating grass. There’s this old wives' tale that dogs eat grass to induce vomiting. While that’s sometimes true, a study published in Applied Animal Behaviour Science suggests that most grass-eating isn't actually followed by vomiting. Instead, it might be a localized way to soothe a rumbling gut or add a bit of fiber to move things along. If your dog is suddenly acting like a lawnmower, their stomach is likely bothering them.
When the "Downward Dog" Isn't Yoga
If you see your dog stretching out their front legs while keeping their butt high in the air—the classic "play bow" position—and they stay there for a long time, pay attention. This is often called the "prayer position."
It’s not cute. It’s a sign of abdominal pain.

By stretching out, they are trying to take the pressure off their internal organs. If you see this, along with a tucked-up abdomen (where their belly looks sucked in and tight), you’re looking at a dog in significant discomfort. Dr. Jerry Klein, the Chief Veterinary Officer for the AKC, often points out that a "splinted" or hard abdomen is a red flag for something more serious like bloat or pancreatitis.
Why Their Dinner Manners Matter
Gurgling. You know that sound your stomach makes when you’re hungry? Dogs get it too, but louder. It's called borborygmi. It’s basically gas moving through the intestines. A little bit is normal. A symphony of it, audible from across the room, usually means something is fermenting in there that shouldn't be.
Then there’s the "food strike."
A healthy dog usually views a bowl of kibble as the highlight of their existence. When they sniff it and walk away, that’s a massive data point. Some owners think their dog is just being "picky." Rarely. Dogs are opportunistic scavengers. If they aren't eating, their GI tract is likely sending "closed for repairs" signals to the brain.
Understanding the "Why" Behind the Belly Ache
It helps to know what’s actually happening inside. Dietary indiscretion—vetspeak for "eating trash"—is the leading cause. But it can be more complex.
- Food Sensitivities: Sometimes it's the chicken in the kibble.
- Parasites: Giardia or roundworms love to mess with digestion.
- Infections: Salmonella isn't just a human problem.
- Organ Issues: Kidney or liver issues often manifest as stomach trouble first.
The Graded Scale of Dog Poop
We have to talk about it. The Bristol Stool Chart exists for humans, but dog owners have their own internal version. If the "output" looks like soft-serve ice cream or, worse, flavored water, the large intestine is irritated.

If you see blood, don't spiral immediately, but do get worried. Fresh, bright red blood (hematochezia) usually means the irritation is lower down in the colon. Dark, tarry, black stool (melena) is more concerning because it means there's digested blood, likely coming from the stomach or upper small intestine. This is a "call the vet right now" situation.
Pancreatitis: The Holiday Danger
This is the big one. Pancreatitis often spikes around Thanksgiving or Christmas because people give their dogs "treats" like ham fat or turkey skin. The pancreas is a little organ with a big job: producing enzymes to break down fat. When it gets hit with a massive fat bomb, it can become inflamed.
The signs of upset stomach in dogs caused by pancreatitis are usually much more severe. We're talking lethargy, repeated vomiting, and a total refusal to move. It’s incredibly painful. If your dog ate something greasy and now looks like they’re dying, they might actually be in a medical emergency.
Distinguishing Between "Wait and See" and "Emergency Room"
How do you know if you can just skip breakfast or if you need to load them into the car at 2:00 AM?
The 24-Hour Rule
If your dog vomits once but is still bouncy, alert, and acting like their weird self, you can usually wait. Fast them for 12 to 24 hours (consult your vet first, especially for puppies or tiny breeds who can get hypoglycemic).
The "Red Zone" Signs

- Unproductive retching (trying to vomit but nothing comes out). This is a primary sign of Gastric Dilatation-Volvulus (GDV), or bloat. This is a death sentence without immediate surgery.
- Pale gums. Lift their lip. They should be bubblegum pink. If they are white, grey, or muddy blue, your dog is in shock.
- Extreme lethargy. If they won't get up for a walk or a "W-O-R-D," something is wrong.
Practical Steps to Soothe a Dog's Upset Stomach
If it's just a mild case of "I ate a bug I shouldn't have," you can manage this at home.
- Hydration is tricky. Don't let them gulp a gallon of water after vomiting; they’ll just throw it back up. Give them ice chips or small tablespoons of water every hour.
- The Bland Diet. Forget the fancy grain-free bison kibble for a few days. The gold standard is boiled white rice and boiled chicken breast (no skin, no bones, no seasoning). Some people use lean ground beef, but chicken is usually safer for the fat content.
- Pureed Pumpkin. Not pumpkin pie filling with the sugar and spices—just plain canned pumpkin. The fiber helps "firm up" diarrhea but also helps with constipation. It's weirdly magical for dog guts.
- Probiotics. Keeping a bottle of FortiFlora or a similar canine-specific probiotic in the cupboard is a pro-move. It helps replenish the "good" bacteria that get flushed out during a bout of diarrhea.
Real Talk on Medications
Please, for the love of everything, stop giving your dog Pepto-Bismol or Imodium without a direct "okay" from a professional. Pepto contains salicylates (basically aspirin), which can be toxic in certain doses or mask internal bleeding. Imodium (loperamide) can be dangerous for certain breeds like Collies or Aussies who might have the MDR1 gene mutation.
If you want to help, stick to the bland food and call your vet for a prescription for something like Cerenia (for nausea) or Metronidazole (for inflammation).
A Quick Checklist for the Next Time the Rumbling Starts
Keep a log. It sounds nerdy, but when the vet asks "how many times did he vomit?" and you say "uh, a few," it doesn't help.
- Time: When did it start?
- Consistency: Liquid? Chunky? Color?
- Behavior: Are they wagging their tail or hiding under the bed?
- Triggers: Did they get into the trash? New bag of food? A stressful move?
Most of the time, the signs of upset stomach in dogs are just a temporary blip. They’re scavengers by nature, and their systems are built to handle some pretty gross stuff. But being the person who notices the subtle lick of the lips or the "prayer stretch" before it turns into a full-blown crisis is what makes you a great owner.
Immediate Action Items
- Check the Gums: Ensure they are pink and moist.
- Feel the Belly: Gently press on their abdomen. If it feels hard as a rock or they yelp, go to the vet.
- Monitor the Hydration: Perform the "scruff test"—pinch the skin between their shoulders. If it snaps back, they’re hydrated. If it stays in a tent shape, they need fluids.
- Simplify the Input: Strip the diet back to the basics (rice/chicken) for 48 hours until the stool returns to a normal consistency.
If the symptoms persist for more than 48 hours, or if you see blood, stop Googling and get to a clinic. Your dog's gut health is the foundation of their immune system; taking it seriously keeps them around for the long haul.
