Why Is My Dog Vomiting? Causes, Treatments, and When to Seek Help

Vomiting is a common but concerning symptom in dogs that can range from mild stomach upset to life-threatening conditions. While occasional vomiting may not be alarming, frequent or severe episodes require veterinary attention.

Common Causes of Vomiting in Dogs

1. Dietary Indiscretion

• Scavenging: Eating spoiled food, garbage, or foreign objects (toys, socks).

• Sudden Diet Changes: Switching foods too quickly can upset digestion.

• Food Allergies: Some dogs react to certain proteins or additives.

2. Heat-Related Issues

• Dehydration & Heatstroke: Excessive panting and vomiting in hot weather.

• Symptoms: Thick saliva, red gums, lethargy.

3. Gastrointestinal Blockages

• Causes: Bones, toys, or hairballs obstructing the intestines.

• Warning Signs: Straining to defecate, loss of appetite, abdominal pain.

4. Pancreatitis

• Triggers: High-fat foods (bacon, grease, table scraps).

• Symptoms: Repeated vomiting, arched back (abdominal pain), diarrhea.

5. Toxins & Poisoning

• Common Culprits: Chocolate, xylitol (in sugar-free gum), rat poison, toxic plants.

• Action: Contact a vet or pet poison control immediately.

When to See a Vet

• Emergency Signs:

  • Blood in vomit (red or coffee-ground appearance).

  • Distended abdomen (risk of bloat/GDV in large breeds).

  • Lethargy, fever, or collapse.

• Chronic Vomiting: If vomiting persists beyond 24 hours.

Home Care for Mild Cases

• Fasting: Withhold food for 4–6 hours (water should still be available).

• Bland Diet: Offer boiled chicken and rice in small portions.

• Hydration: Provide ice cubes or electrolyte solutions (Pedialyte).

Prevention Tips

• Keep trash secured.

• Avoid fatty human foods.

• Use slow feeders if your dog eats too fast.

• Regular parasite prevention (worms can cause vomiting).

Final Advice: If in doubt, consult your veterinarian—early intervention can save lives.
