Why Is My Dog Vomiting?

Dog vomiting is the forceful expulsion of stomach and upper intestinal contents, and it’s important to distinguish it from regurgitation, which is a passive process where undigested food comes back up without abdominal contractions. When your dog keeps throwing up, it’s their body’s way of expelling something undesirable, whether it’s inappropriate food, toxins, or a sign of underlying illness.

There are many reasons why does my dog keep throwing up, ranging from simple dietary indiscretion to more serious health concerns. Occasional, isolated incidents may not be cause for alarm, but persistent vomiting requires attention. The color and consistency of the vomit can provide important clues about the underlying cause, which we’ll explore in the next section. Understanding the nature of your dog’s vomiting is the first step in determining how to help them feel better.

What Causes Vomiting in Dogs?

When wondering why does my dog keep throwing up, there are numerous potential causes ranging from minor to serious:

Common Causes:

  • Dietary indiscretion: Eating too fast, overeating, consuming garbage, or sudden diet changes.
  • Dietary intolerance or allergy: Sensitivity to specific ingredients in food.
  • Bacterial or viral infections: Such as parvovirus, especially in puppies.
  • Parasites: Intestinal worms can cause irritation and vomiting.
  • Toxins or chemicals: Ingestion of household cleaners, pesticides, or toxic plants.
  • Medications: Some drugs may cause stomach upset as a side effect.
  • Car sickness: Motion sickness during travel.
  • Stress or anxiety: Changes in environment or routine can trigger vomiting.
  • More Serious Causes:

  • Pancreatitis: Inflammation of the pancreas, often from high-fat foods.
  • Kidney or liver disease: Organ dysfunction leading to toxin buildup.
  • Gastrointestinal obstruction: From foreign objects like toys or bones.
  • Certain cancers: Tumors in the digestive tract.
  • Addison’s disease: Hormonal disorder affecting stress response.
  • Inflammatory bowel disease: Chronic inflammation of the intestinal tract.
  • Immediate Home Care: What You Can Do at Home

    For occasional vomiting when your dog otherwise seems normal, these steps may help:

  • Withhold food: Temporarily fasting for 12-24 hours (shorter for puppies) can rest the gastrointestinal tract6. Ensure fresh water remains available to prevent dehydration.
  • Ice chips: Instead of large water amounts, offer ice chips to prevent gulping too much water too quickly.
  • Bland diet: After the fasting period, introduce a bland diet in small, frequent meals. The most common bland diet consists of plain, boiled white meat chicken (no skin or bones) or lean ground turkey mixed with plain, white rice.
  • Probiotics: These can help restore healthy gut bacteria1.
  • Monitor closely: Watch for additional symptoms and ensure your dog is keeping down water.
  • Important: If your dog keeps throwing up despite these measures, or if symptoms worsen, contact your veterinarian. Never give human medications to your dog without veterinary guidance, as some can be toxic to pets.

    When to Call the Vet: Warning Signs and Red Flags

    While occasional vomiting might resolve with home care, certain signs indicate when dog vomiting when to worry becomes a real concern. Contact your veterinarian immediately if you notice:

  • Vomiting persists for more than 24 hours or occurs frequently in a short period
  • Blood in vomit (fresh red or coffee-ground appearance)
  • Suspicion of toxin ingestion (plants, chemicals, human medications)
  • Signs of abdominal pain (whining, trembling, reluctance to move)
  • Lethargy or weakness beyond normal sleepiness
  • Vomiting in puppies, especially if not fully vaccinated
  • Existing health conditions like diabetes, kidney disease, or cancer
  • Signs of dehydration (dry gums, loss of skin elasticity, sunken eyes)
  • Bloated or distended abdomen (potential GDV emergency)
  • Also having diarrhea (especially if bloody)
  • Non-productive retching (could indicate bloat)
  • These red flags suggest your dog illness throwing up might be more than a simple stomach upset and requires professional assessment. When in doubt, it’s always better to err on the side of caution and consult your veterinarian.

    Diagnostic and Treatment Options Your Vet May Recommend

    If your dog keeps throwing up persistently, your veterinarian may recommend:

    Diagnostic Tests:

  • Physical examination: Checking for pain, dehydration, or abdominal abnormalities.
  • Blood tests: Assessing organ function, electrolyte levels, and blood cell counts.
  • X-rays or ultrasound: Looking for obstructions, tumors, or other abnormalities.
  • Fecal tests: Checking for parasites or bacterial infections.
  • Endoscopy: Using a camera to visualize the digestive tract.
  • Treatment Options:

  • Fluid therapy: Correcting dehydration and electrolyte imbalances through intravenous or subcutaneous fluids.
  • Antiemetic medications: Drugs like maropitant or ondansetron to control nausea and vomiting.
  • Gastroprotectants: Medications like omeprazole or famotidine to reduce stomach acid.
  • Dietary management: Prescription diets for sensitive stomachs or specific health conditions.
  • Antibiotics or antiparasitics: If infection or parasites are identified.
  • Surgery: In cases of obstruction or certain anatomical issues.
  • The specific treatment will depend on the underlying cause of your dog’s vomiting. Your veterinarian will develop a tailored plan based on the diagnosis and your dog’s individual needs.

    Conclusion

    Dog vomiting is a common issue that ranges from minor, self-resolving incidents to signs of serious health conditions. While occasional vomiting may respond to simple home care like fasting and a bland diet, persistent or severe vomiting requires veterinary attention. The key is to observe your dog’s overall behavior—if they’re otherwise bright, alert, and responsive, simple monitoring may suffice. But if vomiting continues or is accompanied by other concerning symptoms like lethargy, pain, or blood, don’t hesitate to contact your veterinarian. Remember that prompt attention to persistent dog throwing up can prevent complications and ensure your furry friend gets back to their happy, healthy self as quickly as possible.

    FAQ

    How long should I wait before taking my dog to the vet for vomiting?

    If your puppy is vomiting, especially if they’re not fully vaccinated, or if your dog is vomiting repeatedly and can’t keep water down, it’s best to contact your vet immediately. For adult dogs with a single vomiting episode but who otherwise seem normal, you can monitor for 12-24 hours. However, if vomiting persists beyond this timeframe, or if any red flags appear (such as blood in vomit, lethargy, or signs of pain), seek veterinary care promptly.

    What foods can help settle my dog’s stomach after vomiting?

    After vomiting has stopped, a bland diet is recommended. This typically consists of plain, boiled white meat chicken (without skin or bones) mixed with plain white rice. You can also offer plain canned pumpkin (not pie filling) as it contains fiber that can help regulate digestion. Offer small, frequent meals rather than one large portion, and gradually transition back to their regular food over several days once vomiting has resolved.

    Can frequent vomiting indicate a serious chronic condition?

    Yes, frequent or chronic dog vomiting can indicate underlying health issues that require veterinary attention. Potential causes include food allergies or intolerances, inflammatory bowel disease, chronic pancreatitis, kidney or liver disease, endocrine disorders like Addison’s disease, or even certain cancers. If your dog keeps throwing up intermittently over days or weeks, even if they seem otherwise normal, it’s important to have them evaluated by a veterinarian to identify and address any underlying conditions.
