Understanding Digestive Upsets

While occasional digestive upset is common in dogs, persistent vomiting or severe diarrhea is a leading cause of emergency visits. Pet owners must differentiate between mild illness and life-threatening conditions.

Common Causes

  • Dietary indiscretion: Eating garbage, spoiled food, or non-food items (e.g., socks, stones).
  • Gastroenteritis: Inflammation of the stomach and intestines, often caused by viruses or bacteria.
  • Parvo in puppies: A highly contagious and deadly viral disease, causing bloody diarrhea and severe vomiting.
  • Parasites: Intestinal worms (e.g., Roundworms, Hookworms) or protozoa (e.g., Giardia) that irritate the gut lining.
  • Pancreatitis: Inflammation of the pancreas, often triggered by a sudden intake of fatty food.

Emergency Signs

Seek immediate veterinary care if you observe any of the following:

  • Blood in stool: Fresh red blood (hematochezia) or dark, tarry stool (melena).
  • Persistent vomiting: Vomiting multiple times an hour or vomiting that lasts more than 24 hours.
  • Lethargy: Extreme tiredness, collapse, or unresponsiveness.
  • Dehydration: Tacky gums, sunken eyes, or skin tenting when gently pinched.
  • Bloated or painful abdomen: Especially concerning in deep-chested breeds.

Frequently Asked Questions

When should I worry about dog vomiting?

If vomiting persists more than 24 hours, occurs with blood, or is accompanied by lethargy or collapse, it is an emergency and requires immediate veterinary attention.

What should I feed my dog after vomiting and diarrhea?

Only feed a bland diet (like boiled chicken and rice, or a veterinary-recommended prescription diet) in small, frequent meals, and only after consulting with your veterinarian and ensuring vomiting has ceased.

If you seek a second opinion or lack the primary diagnosis facilities at your location, you can connect with your vet or consult a VOSD specialist at the nearest location or with VOSD CouldVet™ online.
