If your dog is shaking or trembling, it can be concerning. While some causes are harmless, others may indicate an underlying health issue that needs attention. In this guide, we’ll explore the most common reasons why dogs shake, how to identify symptoms, and what actions you should take to ensure your pet’s well-being.
Common Causes of Shaking in Dogs
Shaking can result from physical, emotional, or environmental factors. Here are the most common causes:
1. Cold Weather or Hypothermia
Just like humans, dogs can shiver when they’re cold. Smaller dogs, short-haired breeds, and puppies are especially susceptible to cold temperatures.
Signs of cold-related shaking:
- Trembling when outside or in cold environments
- Curling up or seeking warmth
- Cold ears or paws
What to Do:
- Provide a warm environment with blankets or a dog sweater.
- Limit outdoor exposure during cold weather.
- If shaking persists indoors, consult a vet.
2. Anxiety, Fear, or Stress
Dogs may shake due to emotional distress caused by loud noises (e.g., fireworks, thunderstorms), unfamiliar environments, or separation anxiety.
Signs of stress or anxiety:
- Tail tucked between the legs
- Panting or pacing
- Avoiding eye contact or seeking comfort
What to Do:
- Comfort your dog with a calm voice and physical reassurance.
- Create a safe space where your dog feels secure.
- Consider training or behaviour modification for long-term anxiety management.
For severe anxiety, consult a veterinarian about possible treatments, including anxiety-reducing supplements or medications.
3. Excitement or Anticipation
Shaking can occur when dogs are overly excited, such as when greeting their owners or anticipating a walk or meal. This type of shaking is temporary and not harmful.
Signs of excitement-related shaking:
- Wagging tail and playful behaviour
- Jumping or barking with enthusiasm
- Shaking stops once the excitement subsides
What to Do:
- Allow your dog to release energy through play or exercise.
- Maintain a calm tone and reward relaxed behaviour to help them manage excitement.
4. Pain or Injury
Shaking may be a sign that your dog is in pain due to an injury, arthritis, or other medical conditions.
Signs of pain:
- Whining or yelping
- Limping or reluctance to move
- Sensitivity when touched
What to Do:
- Gently examine your dog for signs of injury.
- Avoid handling areas that cause pain.
- Contact your veterinarian for an examination and pain management options.
5. Illness or Infection
Certain illnesses, such as distemper or canine influenza, can cause shaking along with other symptoms like fever, lethargy, and coughing.
Signs of illness:
- Shaking combined with lethargy, vomiting, or diarrhea
- Loss of appetite
- Fever or rapid breathing
What to Do:
- Monitor your dog’s symptoms closely.
- Seek immediate veterinary care if your dog shows signs of serious illness.
- Ensure your dog is up-to-date on vaccinations to prevent diseases like distemper.
6. Generalized Tremor Syndrome (GTS)
Also known as “white dog shaker syndrome,” GTS is a condition that causes uncontrollable tremors in dogs, particularly small breeds like Maltese and West Highland Terriers.
Symptoms of GTS:
- Full-body tremors that worsen with stress
- No obvious cause for shaking
- Normal appetite and energy levels
What to Do:
- Consult your veterinarian for a diagnosis.
- Treatment often involves corticosteroids to reduce inflammation.
7. Low Blood Sugar (Hypoglycemia)
Hypoglycemia is more common in small breeds, puppies, and dogs with certain medical conditions. Low blood sugar can cause shaking, weakness, and confusion.
Symptoms of hypoglycemia:
- Shaking or trembling
- Weakness or collapse
- Disorientation or lethargy
What to Do:
- Offer a small amount of honey or a sugar solution if you suspect low blood sugar.
- Seek veterinary care to determine the underlying cause.
8. Poisoning or Toxin Exposure
Shaking may be a sign that your dog has ingested something toxic, such as chocolate, xylitol (artificial sweetener), or certain household plants.
Symptoms of poisoning:
- Shaking or seizures
- Vomiting or diarrhea
- Excessive drooling or difficulty breathing
What to Do:
- Contact your veterinarian or an emergency pet poison hotline immediately.
- Provide information about the suspected toxin and follow your vet’s instructions.
When to See a Vet
While occasional shaking may not be a cause for concern, certain situations warrant immediate veterinary attention:
- Shaking persists for an extended period without a clear cause
- Your dog shows additional symptoms like lethargy, vomiting, or difficulty walking
- You suspect poisoning or severe pain
- Your dog has a history of medical conditions that could be related to the shaking
Early intervention can prevent complications and ensure your dog’s safety.
How to Prevent Shaking in Dogs
Here are some preventive measures to reduce the likelihood of shaking episodes:
- Keep Your Dog Warm: Provide appropriate clothing and limit outdoor exposure in cold weather.
- Manage Anxiety: Use calming techniques, training, and positive reinforcement to reduce fear and stress.
- Monitor Health: Schedule regular veterinary checkups and vaccinations to prevent illnesses.
- Avoid Toxic Substances: Keep harmful foods, chemicals, and plants out of your dog’s reach.
- Ensure Proper Nutrition: Feed your dog a balanced diet to prevent issues like low blood sugar.
