Common Causes of Dog Shaking and Vomiting
Several factors can lead to dog tremors vomiting. It’s important to consider the dog’s age, breed, recent activities, and diet when trying to pinpoint the cause.
Digestive Upset
The most frequent culprits for dog shaking and vomiting are issues related to their digestive tract. This can stem from simple dietary indiscretions to more complex gastrointestinal diseases.
- Dietary Indiscretions: Dogs are notorious for eating things they shouldn’t. This can include spoiled food, garbage, non-food items (like socks or toys), or even just a sudden change in their regular diet. When the digestive system encounters something it can’t process, it often reacts by expelling it through vomiting and may cause the dog to shake due to discomfort or nausea.
- Food Allergies and Sensitivities: Some dogs develop allergies or sensitivities to certain ingredients in their food, such as grains, proteins (like chicken or beef), or additives. Symptoms can include vomiting, diarrhea, skin issues, and sometimes general malaise leading to shaking.
- Gastroenteritis: This is inflammation of the stomach and intestines. It can be caused by infections (viral or bacterial), parasites, or dietary issues. Symptoms often include vomiting, diarrhea, lethargy, and abdominal pain, which can cause a dog to tremble.
- Intestinal Blockage: If a dog ingests a foreign object that becomes lodged in their digestive tract, it can cause a severe blockage. This is a life-threatening condition that leads to persistent vomiting, abdominal pain, dehydration, and often a sick dog shaking. The blockage prevents food and water from passing, leading to severe distress.
- Pancreatitis: This is inflammation of the pancreas, often triggered by a high-fat meal. It causes severe abdominal pain, vomiting, lethargy, and sometimes fever. The pain and discomfort can manifest as shaking.
- Bloat (Gastric Dilatation-Volvulus – GDV): Particularly common in deep-chested breeds, bloat occurs when the stomach fills with gas and twists, cutting off blood supply. Symptoms include unproductive retching, abdominal distension, excessive drooling, restlessness, and the dog may shake from shock and pain. This is a critical emergency.
Infections and Illnesses
Beyond the digestive system, various systemic infections and illnesses can present with shaking and vomiting.
- Viral Infections: Parvovirus, distemper, and adenovirus are serious viral diseases that can affect dogs, especially puppies. They often cause severe vomiting, diarrhea, lethargy, fever, and neurological signs, including tremors or shaking. Puppy shaking vomiting is a particularly concerning sign of potentially life-threatening viral infections.
- Bacterial Infections: Leptospirosis, Salmonella, and certain types of E. coli can cause gastrointestinal upset, fever, and systemic illness, leading to shaking and vomiting.
- Parasitic Infections: Intestinal parasites like roundworms, hookworms, and Giardia can irritate the digestive tract, leading to vomiting, diarrhea, weight loss, and a general feeling of being unwell that could cause shaking.
- Kidney or Liver Disease: When these vital organs are compromised, toxins can build up in the bloodstream, leading to nausea, vomiting, loss of appetite, lethargy, and sometimes neurological signs like tremors.
- Diabetes Mellitus: In diabetic dogs, particularly if their blood sugar is poorly controlled or if they experience diabetic ketoacidosis, they can exhibit symptoms like vomiting, lethargy, increased thirst, and sometimes tremors.
- Addison’s Disease (Hypoadrenocorticism): This endocrine disorder occurs when the adrenal glands don’t produce enough essential hormones. Symptoms can be vague and episodic, including vomiting, diarrhea, lethargy, weakness, and tremors.
Neurological Issues
Problems originating in the brain or nervous system can also manifest as shaking and vomiting.
- Seizures: While seizures are characterized by involuntary muscle activity, they can sometimes be preceded or followed by vomiting. A dog experiencing a seizure might shake or tremble violently. Therefore, dog seizures vomiting is a direct indicator of a neurological event.
- Brain Tumors or Injuries: Lesions in the brain can affect various functions, including those that control nausea and motor control, leading to both vomiting and tremors.
- Vestibular Disease: This condition affects the inner ear and balance system, leading to symptoms like head tilting, loss of balance, circling, vomiting, and nystagmus (involuntary eye movements). While not always directly causing shaking, the severe disorientation can lead to trembling.
Toxin Ingestion
Accidental ingestion of poisons or toxins is a critical cause of shaking and vomiting.
- Household Chemicals: Cleaning products, antifreeze, rodenticides (rat poison), and certain houseplants can be highly toxic to dogs and can cause severe gastrointestinal distress, neurological signs, and shaking.
- Human Medications: Many human medications, from pain relievers to antidepressants, are extremely dangerous for dogs and can cause serious poisoning, including vomiting and tremors.
- Certain Foods: Foods toxic to dogs, like chocolate, xylitol (an artificial sweetener found in many sugar-free products), grapes, and raisins, can trigger severe reactions, including vomiting and neurological effects.
Other Causes
- Heatstroke: Overheating can cause rapid breathing, panting, lethargy, vomiting, and muscle tremors. This is a medical emergency.
- Anxiety or Fear: While less common as a primary cause of persistent vomiting, extreme stress or fear can sometimes trigger a dog to shake and even experience nausea or regurgitation.
- Motion Sickness: Some dogs become nauseous during car rides or other forms of travel, leading to vomiting and panting or trembling.
- Post-Surgery or Anesthesia: Some dogs may experience nausea, vomiting, or tremors as a reaction to anesthesia or pain medication following surgery.
Symptoms to Watch For
Beyond the core symptoms of shaking and vomiting, other signs can help you and your veterinarian diagnose the problem. A pet shaking vomiting situation warrants close observation for these additional clues:
- Lethargy and Weakness: A general lack of energy, reluctance to move, and appearing weak are common signs of illness.
- Loss of Appetite: Refusal to eat or drink can indicate nausea or a more serious underlying issue.
- Diarrhea: While vomiting is present, diarrhea may also occur, sometimes with blood or mucus.
- Abdominal Pain: Your dog might whine, yelp when touched, or exhibit a hunched posture if they are experiencing abdominal pain. This is often seen with dog digestive issues shaking.
- Drooling: Excessive salivation can be a sign of nausea or ingestion of something irritating.
- Pacing or Restlessness: Some dogs will pace or appear agitated when they feel unwell.
- Changes in Urination or Defecation: Increased thirst, frequent urination, or a change in stool consistency can be related.
- Fever: An elevated body temperature can indicate infection.
- Pale Gums: Pale or white gums can suggest shock or severe anemia.
- Jaundice: Yellowing of the gums, skin, or whites of the eyes can indicate liver problems.
Differentiating Types of Shaking
The nature of the shaking can provide clues.
- Fine Tremors: Often associated with nausea, fear, or low blood sugar.
- Muscle Tremors/Twitching: Can indicate neurological problems, seizures, or toxin ingestion.
- Shivers/Shivering: May be due to cold, pain, fever, or shock.
When a dog is nauseous shaking, the tremors are often a response to feeling unwell, similar to how humans might shiver when sick.
When to See a Vet Immediately
It’s crucial to know when to seek professional help. Some symptoms are more urgent than others. Here’s when you should not delay in contacting your veterinarian or emergency animal hospital:
- Persistent Vomiting: If your dog vomits multiple times in a short period or cannot keep any liquids down.
- Blood in Vomit or Stool: Any presence of fresh or digested blood is a serious sign.
- Severe Lethargy or Collapse: If your dog is unresponsive, extremely weak, or collapses.
- Signs of Severe Pain: Vocalization, guarding the abdomen, or extreme restlessness.
- Abdominal Distension: A swollen or hard abdomen, especially if accompanied by retching without producing vomit (a sign of bloat).
- Difficulty Breathing: Rapid or labored breathing.
- Suspected Toxin Ingestion: If you know or suspect your dog has eaten something poisonous.
- Known Pre-existing Conditions: If your dog has a chronic illness like diabetes or kidney disease and shows these symptoms.
- If Your Dog is a Puppy: Puppy shaking vomiting can be a sign of serious infections like Parvovirus, which requires immediate treatment.
- Neurological Signs: If you observe weakness, paralysis, disorientation, or other signs suggesting dog seizures vomiting is involved.
Diagnostic Approaches by Veterinarians
When you bring your dog to the vet, they will perform a thorough examination and may recommend various diagnostic tests to determine the cause of the shaking and vomiting.
Physical Examination
The veterinarian will:
- Check your dog’s vital signs (temperature, heart rate, respiratory rate, blood pressure).
- Assess hydration levels.
- Palpate the abdomen to check for pain, distension, or masses.
- Examine the mouth for any foreign objects or signs of poisoning.
- Check the gums and mucous membranes for color.
- Listen to the heart and lungs with a stethoscope.
- Assess neurological function.
Diagnostic Tests
Based on the initial findings, the vet might suggest:
- Bloodwork:
- Complete Blood Count (CBC): To check for infection, anemia, or inflammation.
- Biochemistry Panel: To assess organ function (kidneys, liver), electrolytes, blood sugar, and pancreatic enzymes.
- Urinalysis: To evaluate kidney function and check for infection or metabolic issues.
- Fecal Examination: To detect intestinal parasites.
- X-rays (Radiographs): Useful for detecting foreign objects in the digestive tract, diagnosing intestinal blockages, or identifying masses.
- Ultrasound: Provides detailed images of abdominal organs, helping to diagnose pancreatitis, intestinal inflammation, or other abnormalities.
- Specific Toxin Tests: If poisoning is suspected.
- Neurological Exam: If neurological issues are suspected, further tests like MRI or CT scans might be recommended.
Treatment and Management
Treatment will depend entirely on the underlying cause.
Supportive Care
In many cases, supportive care is crucial while addressing the root cause:
- Fluid Therapy: Intravenous (IV) fluids are often administered to combat dehydration caused by vomiting and diarrhea.
- Anti-nausea Medications: To help control vomiting and allow the stomach to rest.
- Pain Management: If pain is a significant factor, appropriate pain relievers will be prescribed.
- Dietary Management: Once vomiting subsides, a bland, easily digestible diet (like boiled chicken and rice) may be recommended.
Specific Treatments
- Antibiotics: For bacterial infections.
- Antiparasitics: To treat intestinal parasites.
- Surgery: May be required for intestinal blockages or bloat.
- Anticonvulsants: To manage seizures.
- Dietary Changes: For food allergies or sensitivities.
- Specific Antidotes: For certain toxin ingestions.
Prevention Strategies
While not all instances of shaking and vomiting can be prevented, several measures can reduce the risk:
- Proper Diet: Feed a high-quality, balanced diet appropriate for your dog’s age, breed, and activity level. Avoid sudden changes in food.
- Secure Your Home and Yard: Keep toxic substances, medications, and small objects out of reach. Be aware of poisonous plants in your home and garden.
- Supervise Your Dog: Especially during walks or when they have access to new environments, prevent them from eating unknown objects or substances.
- Regular Veterinary Check-ups: Annual or semi-annual wellness exams can help catch health issues early.
- Vaccinations and Deworming: Keep your dog up-to-date on vaccinations and deworming to protect against common infectious diseases and parasites.
- Avoid Overfeeding and High-Fat Foods: Particularly for breeds prone to pancreatitis.
