Most pet owners have seen their dog or cat deal with an upset stomach at some point. Maybe it’s a day of loose stools, a skipped meal, or a bit of vomiting. In many cases, these episodes are short-lived and resolve on their own. But sometimes, what looks like a minor tummy issue can actually be a sign of something more serious.
At Norgate Animal Hospital, we often remind pet parents that the digestive system plays a big role in overall health. Paying attention to gastrointestinal (GI) changes can help you catch early warning signs before they become bigger problems.
When an upset stomach is truly minor
Occasional digestive issues can happen in otherwise healthy pets. Common causes include eating something unusual, mild dietary intolerance, or a sudden change in food. If your pet vomits once but then goes back to normal eating and energy, it may not be cause for concern.
But here’s the key: frequency and persistence matter. Repeated vomiting, diarrhea lasting more than a day, or a sudden change in appetite is rarely “just a stomach bug.”
Signs that point to something more serious
GI issues can be linked to underlying diseases, parasites, infections, or even systemic conditions affecting organs outside the digestive tract. Symptoms that shouldn’t be ignored include:
-
Repeated vomiting or diarrhea lasting more than 24–48 hours
-
Blood in stool or vomit
-
Significant weight loss without explanation
-
Chronic soft stools or alternating constipation and diarrhea
-
Straining, bloating, or signs of abdominal pain
-
Loss of appetite or sudden disinterest in food
-
Lethargy or weakness that accompanies stomach issues
These are red flags that your pet needs veterinary attention.
Common gastrointestinal conditions in pets
Digestive problems can stem from many causes. Some of the conditions we diagnose and manage at Norgate Animal Hospital include:
-
Parasites: Intestinal worms and protozoa can cause diarrhea, weight loss, and poor coat condition. Even indoor pets are not completely safe from them.
-
Inflammatory bowel disease (IBD): A chronic condition where the intestines become inflamed, leading to ongoing digestive upset.
-
Food allergies or sensitivities: Some pets react poorly to certain proteins or ingredients, leading to chronic vomiting or diarrhea.
-
Pancreatitis: Inflammation of the pancreas, often linked to fatty foods, can cause severe abdominal pain, vomiting, and loss of appetite.
-
Foreign body ingestion: Pets sometimes swallow things they shouldn’t—like toys, string, or bones—which can block the digestive tract.
-
Liver or kidney disease: Problems in these organs can show up first as GI signs such as nausea, vomiting, or poor appetite.
-
Cancer: Tumors in the stomach or intestines can mimic common GI issues in their early stages.
What owners can do at home (and what not to do)
If your pet has mild digestive upset but is otherwise bright and active, you can support them with short-term adjustments like:
-
Withholding food for 12 hours (dogs only) and then reintroducing a bland diet such as boiled chicken and rice.
-
Making sure fresh water is always available to prevent dehydration.
-
Transitioning foods gradually if you’re switching brands or diets.
However, it’s important not to rely on home care if symptoms are severe, persistent, or accompanied by other warning signs. Over-the-counter remedies meant for humans should never be given without veterinary guidance, as many can be harmful to pets.
The role of your veterinarian
Because GI issues can be caused by anything from parasites to chronic disease, diagnosis often requires a step-by-step approach. Your veterinarian may recommend fecal testing, blood work, imaging, or diet trials to get to the root of the problem.
The earlier these investigations begin, the better the outcome. A case of vomiting that seems simple could turn out to be pancreatitis or a foreign object, where timely care can make all the difference.
Digestive upset in pets isn’t always something to brush off. While minor issues happen, persistent or severe symptoms are often a sign of something more. Understanding when “just an upset stomach” might be a bigger health concern is one of the best ways you can advocate for your pet’s well-being.
At Norgate Animal Hospital, we’re here to help you sort through the uncertainty, provide answers, and get your pet back to feeling like themselves. If you notice changes in your pet’s digestion that don’t resolve quickly, don’t wait—reach out for veterinary care.
