Dog Keeps Shivering And Shaking

Seeing your dog shiver or shake can be alarming. While occasional trembling is normal, persistent shaking often signals something deeper. This guide helps you understand the possible reasons why your dog keeps shivering and shaking, and what steps to take next.

Quick Q&A: Common Questions

Question: Why is my dog shaking? Answer: Shaking can stem from simple causes like cold or excitement, but it may also indicate pain, nausea, anxiety, or a medical condition such as poisoning, kidney disease, or neurological issues. Observe your dog's behavior and environment to help narrow down the cause.

Common Causes of Shivering and Shaking

1. Cold or Temperature Regulation

Small breeds, short-haired dogs, and seniors lose body heat quickly. If your dog is shivering and it is cold outside or inside your home, they are likely just trying to warm up. Providing a blanket or adjusting the thermostat often resolves this.

2. Excitement or Anticipation

Many dogs shake when excited. You might see this when you grab the leash for a walk, when guests arrive, or before mealtime. This type of shaking is typically brief and accompanied by tail wagging and happy behavior.

3. Anxiety or Stress

Fear-related shaking is common during thunderstorms, fireworks, vet visits, or car rides. A fearful dog may also pant, pace, tuck their tail, or hide. Chronic anxiety can lead to more frequent trembling episodes.

4. Pain or Discomfort

Dogs often shake when they are hurting. Common sources include dental pain, arthritis, injury, or abdominal discomfort. If the shaking is localized to a specific body part (like a leg), the source of pain may be nearby.

5. Nausea

Nausea from motion sickness, eating something bad, or an underlying condition can cause shivering. You may also notice lip licking, drooling, or vomiting.

6. Neurological Conditions

Conditions like tremors, seizures, or vestibular disease can cause shaking. Tremors are often rhythmic and may affect the whole body or just the head. Seizures can involve shaking, stiffness, loss of consciousness, or unusual behavior.

7. Poisoning or Toxin Exposure

Certain toxins cause muscle tremors and shaking. Common dangers include chocolate, xylitol (artificial sweetener), caffeine, marijuana, and snail bait. If you suspect poisoning, seek emergency veterinary care immediately.

8. Metabolic and Systemic Illnesses

Kidney disease, liver problems, low blood sugar (hypoglycemia), or electrolyte imbalances can cause shaking. These are more common in senior dogs or those with existing health issues.

9. Old Age and Generalized Tremor Syndrome

Some older dogs develop a condition called generalized tremor syndrome (also known as "white shaker dog syndrome"). It causes full-body tremors but is not painful and often responds well to medication. Small breeds like Maltese and West Highland White Terriers are predisposed.

When to See a Veterinarian

Seek immediate veterinary care if your dog is shaking and also shows any of these signs:

  • Vomiting or diarrhea
  • Lethargy or weakness
  • Difficulty breathing
  • Stiffness or inability to stand
  • Seizures or loss of consciousness
  • Pale gums
  • Known or suspected toxin exposure

Make an appointment if:

  • Shaking persists for more than a few hours
  • It is accompanied by limping, crying, or guarding a body part
  • Your dog seems unusually anxious or distressed
  • The shaking is new or worsening

What to Expect at the Vet

Your veterinarian will start with a thorough history and physical exam. Be ready to answer questions about when the shaking started, what makes it better or worse, and any other symptoms. Diagnostic tests may include:

  • Blood work to check organ function, blood sugar, and electrolytes
  • Urinalysis
  • X-rays if pain or injury is suspected
  • Neurological exam if a brain or nerve issue is possible

Treatment depends entirely on the underlying cause. It might range from pain medication and anti-nausea drugs to antibiotics, dietary changes, or specific therapies for chronic conditions.

Home Care and Prevention

For mild cases where a serious cause has been ruled out, you can try these home care strategies:

  • Keep your dog warm: Provide a cozy bed, blankets, and a warm room. Dog sweaters help small or short-haired breeds.
  • Reduce stress: Create a safe space away from loud noises. Use calming aids like pheromone diffusers, anxiety wraps, or background music.
  • Monitor diet and activity: Avoid feeding table scraps or known toxins. Ensure regular, gentle exercise to maintain muscle tone and joint health.
  • Routine vet checkups: Annual or semi-annual exams help catch problems early, especially in senior dogs.

Key Takeaways

  • Shivering and shaking in dogs can be harmless or a sign of a serious problem.
  • Common causes include cold, excitement, anxiety, pain, nausea, and medical conditions.
  • Always note any other symptoms and the context of the shaking.
  • When in doubt, consult your veterinarian. Prompt attention can prevent complications and keep your dog comfortable.

Your dog cannot tell you what is wrong, but their body language often provides the clues you need. By staying observant and proactive, you help ensure your furry friend stays healthy and happy.
