Diarrhea and Vomiting in Dogs: When to Worry and What You Can Do

While occasional digestive upset is normal in dogs, chronic or severe vomiting and diarrhea can indicate a more serious health issue. Here’s a guide to understanding these symptoms, when to be concerned, and how to help your dog.

Common Causes of Vomiting and Diarrhea in Dogs

Digestive disturbances can be caused by a range of factors:

1. Dietary Changes

Sudden dietary changes or new treats can disrupt your dog’s digestive system. Transitioning to a new dog food should ideally be done gradually over 7–10 days to prevent stomach upset.

2. Food Allergies or Sensitivities

Certain ingredients can trigger allergies in dogs, leading to vomiting, diarrhea, and itchy skin. Common allergens include beef, dairy, wheat, and soy. If you suspect a food allergy, consult your vet, who may suggest an elimination diet.

3. Infections and Parasites

Bacterial infections (like salmonella) or parasitic infections (like Giardia) can cause vomiting and diarrhea. These are often contracted from contaminated food, water, or environments, especially if your dog enjoys exploring outdoors.

4. Ingesting Foreign Objects

Dogs may swallow non-food items like toys, bones, or household items, leading to intestinal irritation or blockage. If your dog ingests a foreign object, they may need an X-ray to confirm the location and severity of the blockage.

5. Toxic Substances

Items like chocolate, certain plants, household cleaners, or medications not prescribed for dogs can be toxic. If you suspect your dog has ingested something harmful, contact your vet immediately.

6. Underlying Medical Conditions

Chronic conditions such as pancreatitis, kidney disease, and inflammatory bowel disease (IBD) can also manifest through persistent digestive issues. These conditions often require long-term management.

When to Contact Your Veterinarian

Knowing when to seek veterinary care can make a big difference in your dog’s health. Contact your veterinarian if:

  • Symptoms Persist Beyond 24 Hours - Prolonged vomiting or diarrhea can lead to dehydration and further health issues.
  • Blood in Vomit or Stool - Blood may indicate gastrointestinal damage or infection and warrants immediate attention.
  • Lethargy or Weakness - If your dog seems unusually tired or weak, it could signal a serious issue, such as dehydration or infection.
  • Loss of Appetite - A refusal to eat, paired with vomiting or diarrhea, should not be ignored.
  • Signs of Pain - Whining, a tense abdomen, or sensitivity when touched could mean your dog is in pain and needs medical evaluation.

Home Care for Mild Digestive Upset

For cases of mild digestive upset, you can help your dog at home with these steps:

  • Fast and Hydrate - Withhold food for 12–24 hours to allow their stomach to settle. Offer small amounts of water to prevent dehydration.
  • Bland Diet - After fasting, feed your dog a bland diet of boiled chicken and rice for a few days before gradually reintroducing their regular food.
  • Probiotics - Probiotics formulated for dogs can help restore a healthy gut balance.

Diagnostic Tests Your Vet May Suggest

If symptoms are ongoing or severe, your vet may recommend diagnostic tests:

  • Fecal Examination - Tests for parasites like Giardia.
  • Blood Work - Evaluates overall health and checks for infections or organ issues.
  • X-rays or Ultrasound - Identifies blockages or abnormalities in the digestive tract.
  • Allergy Testing - Determines if food or environmental allergies are the cause.

Treatment Options for Digestive Disorders

Treatment will depend on the underlying cause identified by your vet:

  • Medications - Anti-nausea, anti-diarrheal, or antibiotics may be prescribed.
  • Fluid Therapy - For dehydration, your dog may need fluids administered under the skin or intravenously.
  • Diet Changes - A hypoallergenic or special diet may be recommended for food-sensitive dogs.
  • Surgery - In cases of a severe obstruction, surgery may be necessary.

Preventive Measures for Digestive Health

To reduce the risk of vomiting and diarrhea:

  • Introduce New Foods Gradually - Avoid sudden dietary changes.
  • Supervise Outdoor Activities - Prevent your dog from eating non-food items or drinking from potentially contaminated sources.
  • Store Hazardous Items Out of Reach - Keep toxic substances and medications in secure places.
  • Regular Parasite Control - Use preventive treatments to protect against parasites like fleas and ticks.

Conclusion

Vomiting and diarrhea in dogs can be mild or a sign of a more serious issue. By knowing when to seek veterinary care, you can help ensure your dog’s health and well-being. Always monitor symptoms, and don’t hesitate to consult your vet if you have concerns.
