What Should I Do If My Dog Has Diarrhea?
By Marta Lista DVM
If your dog has diarrhea, it can be messy, stressful, and a little alarming especially if it comes on suddenly. We know how upsetting it is to see your pet uncomfortable or unwell. The good news? Diarrhea is a common issue in dogs and often resolves on its own but sometimes it needs a vet’s attention.
At Trail Animal Hospital, we’re here to help you know what’s normal, what’s not, and how to care for your pup in the meantime.
Common Causes of Dog Diarrhea
There are many reasons your dog might have loose stools some mild, some more serious:
- Dietary indiscretion Eating table scraps, garbage, or unfamiliar food is a top cause.
- Sudden diet changes Switching food too quickly can upset your dog’s stomach.
- Food allergies or sensitivities Some ingredients just don’t sit well with certain dogs.
- Parasites Worms, giardia, and other intestinal parasites can cause persistent diarrhea.
- Viral or bacterial infections These can range from mild to more serious, especially in puppies.
- Stress or anxiety New environments, travel, or boarding can trigger digestive upset.
- Chronic conditions Diseases like IBD, pancreatitis, or liver disease may show up as long-term diarrhea.
What You Can Do at Home (If It’s Mild)
If your dog is acting normal otherwise; eating, drinking, playing you can try:
- Withholding food for 12–24 hours (water is fine) to rest the digestive system
- Reintroducing a bland diet: plain boiled chicken and white rice for 1–2 days
- Gradually returning to their regular food after stools begin to firm up
Always avoid giving human medications like Pepto-Bismol or Imodium without vet guidance.
