Few things are more stressful for pet owners than discovering their dog or cat has diarrhea. Whether it’s a single loose stool or multiple trips outside or to the litter box, digestive upset can leave you wondering if it’s something that will pass or if it’s time to call the vet.
The good news is that many cases of mild diarrhea resolve with supportive care. However, some situations require prompt veterinary attention. At Uptown Veterinary Clinic, we’re here to help determine the cause, keep your pet comfortable, and get them back to feeling their best.
Why Do Dogs and Cats Get Diarrhea?
Diarrhea is a symptom that can have many different causes, including:
- Eating something they shouldn't ("dietary indiscretion")
- Sudden diet changes
- Food sensitivities
- Stress or anxiety
- Intestinal parasites
- Viral or bacterial infections
- Certain medications
- Chronic digestive diseases or underlying health conditions
What You Can Do At Home
If your pet is otherwise acting normally and has only mild diarrhea, there are a few things you can do while monitoring them closely:
- Make sure fresh water is always available to prevent dehydration.
- Feed only the diet recommended by your veterinarian. In many cases, a highly digestible or gastrointestinal diet may be appropriate.
- Never give over-the-counter human medications unless your veterinarian specifically recommends them
- Monitor your pet's appetite, energy level, vomiting, and stool consistency.
Before making any dietary changes or starting supplements, it’s always best to contact your veterinary team for guidance.
The Importance of A Healthy Gut Bicrobiome
Inside your pet’s digestive tract lives a community of beneficial bacteria known as the gut microbiome. These microorganisms play an essential role in digestion, immune function, reducing inflammation, and helping keep harmful bacteria in check.
When the microbiome becomes disrupted, a condition called dysbiosis, digestive problems can persist even after the original cause of diarrhea has resolved.
Supporting a healthy microbiome has become an important part of modern diarrhea management.
Why Antibiotics Aren't Always the Answer
For years, antibiotics such as metronidazole were commonly prescribed for dogs with acute diarrhea. However, recent research has shown that in many uncomplicated cases, antibiotics do not help dogs recover faster than supportive care and probiotics. Instead, they may reduce the diversity of beneficial bacteria in the gut and contribute to antimicrobial resistance.
According to the American Veterinary Medical Association, many dogs recover just as quickly (sometimes even better) with nutritional management and therapies that support the gut microbiome rather than disrupt it.
Every pet is different, though. Some cases absolutely do require antibiotics or other medications, especially when there is evidence of a bacterial infection, severe illness, or another underlying medical condition. That’s why a veterinary examination is so important.
How Veterinarians Support Digestive Recovery
Depending on your pet’s condition, treatment may include:
- A thorough physical examination and diagnostic testing
- A prescription gastrointestinal diet
- Probiotics to help restore beneficial bacteria
- Prebiotics that nourish healthy gut microbes
- Parasite testing and treatment if needed
- Fluid therapy to correct dehydration
- Medications to address vomiting, nausea, or inflammation when appropriate
The goal is not simply to stop diarrhea but to restore normal digestive function while treating the underlying cause.
