Dog vomiting: Symptoms, Reasons & Treatments

Imagine you're enjoying a quiet evening at home when, suddenly, your dog begins to retch. A mess on your living room floor follows the unsettling sound. Panic sets in and you are drawn to the dilemma—why is my dog vomiting? Is it something minor, or should you be rushing to the vet? 

Understanding the reasons behind this common yet alarming symptom can be the difference between a minor inconvenience and a major health crisis for your furry friend.

Symptoms of Dog Vomiting

When a dog vomits, it is crucial to distinguish between vomiting and regurgitation. Vomiting is an active process that involves abdominal contractions, whereas regurgitation is a passive process where undigested food comes up effortlessly. Common symptoms that accompany vomiting in dogs include:

  • Retching or heaving: The dog appears to be trying to vomit without producing anything initially.
  • Salivation: Excessive drooling can occur before or after vomiting.
  • Restlessness: Dogs may seem anxious or uncomfortable.
  • Lethargy: A sudden lack of energy or enthusiasm.
  • Loss of appetite: Refusal to eat or drink.
  • Dehydration: Dry gums, sunken eyes, and lethargy can indicate dehydration.

Why Do Dogs Vomit?


Understanding why do dogs vomit involves identifying the underlying causes. These can range from benign to severe and include dietary, environmental, and health-related factors.

  1. Dietary Indiscretion: One of the most common reasons for dog vomiting is eating something they shouldn't. This includes spoiled food, garbage, or foreign objects.
  2. Food Allergies and Intolerances: Certain ingredients in dog food can cause allergic reactions or intolerances, leading to gastrointestinal upset.
  3. Infections: Bacterial, viral, and parasitic infections can result in vomiting. Conditions such as parvovirus, distemper, and kennel cough are notable examples.
  4. Toxins: Ingesting toxic substances like certain plants, human medications, household cleaners, or chemicals can cause severe vomiting.
  5. Motion Sickness: Just like humans, dogs can experience motion sickness during car rides, leading to vomiting.
  6. Illnesses and Medical Conditions: Various diseases and conditions, including kidney or liver disease, pancreatitis, gastroenteritis, and even cancer, can cause vomiting.
  7. Stress and Anxiety: Emotional distress can manifest physically, causing vomiting in some dogs.
  8. Diet Changes: Abrupt changes in diet can upset a dog's stomach, resulting in vomiting.

Causes of Dog Vomiting

Consider the context and accompanying symptoms to determine the specific causes of dog vomiting. If vomiting persists or is accompanied by other concerning signs, it is crucial to seek veterinary care. The primary causes can be categorised into acute and chronic.

  • Acute Vomiting: This is sudden and often short-lived. It can result from dietary indiscretion, infections, or ingestion of toxins. Acute vomiting typically resolves within a few days with proper care.
  • Chronic Vomiting: When vomiting persists over weeks or months, it is considered chronic. Chronic vomiting requires a thorough veterinary investigation to identify underlying conditions such as gastrointestinal diseases, organ dysfunction, or chronic infections.

Treatments for Dog Vomiting

Treatment for dog vomiting depends on the underlying cause. Here are general approaches to managing and treating vomiting in dogs:

  1. Dietary Management: For mild cases, withholding food for 12-24 hours can allow the stomach to settle. Gradually reintroducing a bland diet (boiled chicken and rice) can help.
  2. Hydration: Ensuring the dog remains hydrated is crucial. Offer small amounts of water frequently. In severe cases, intravenous fluids may be necessary.
  3. Medications: Depending on the cause, veterinarians may prescribe antiemetic (anti-vomiting) medications, antibiotics for infections, or medications to address specific conditions.
  4. Avoiding Triggers: Identifying and avoiding dietary triggers or environmental toxins is essential in preventing future episodes.
  5. Veterinary Care: Persistent or severe vomiting requires veterinary attention. Diagnostic tests such as blood work, X-rays, ultrasounds, or endoscopy may be necessary to identify underlying causes.
  6. Specialised Diets: A hypoallergenic or prescription diet may be recommended for dogs with food allergies or intolerances.

Preventing Dog Vomiting

Once you have understood, why do dogs vomit? It is important to take measures for the same. Preventive measures can help reduce the incidence of vomiting in dogs. Here are some tips to keep your dog healthy:

  • Regular Feeding Schedule: Maintain a consistent feeding schedule with high-quality dog food.
  • Avoid Table Scraps: Human food can upset a dog's stomach and lead to vomiting.
  • Pet-Proof Your Home: Ensure that toxic substances and small objects are out of your dog's reach.
  • Gradual Diet Changes: Introduce new foods slowly to prevent gastrointestinal upset.
  • Regular Veterinary Checkups: Routine health checks can help identify potential issues early.

Bottom Line

Vomiting in dogs can be a distressing experience for both pets and owners. Understanding the symptoms, identifying the reasons why your dog is vomiting, and knowing the appropriate treatments can ensure your furry friend's health and comfort.
