Why Is My Dog Shaking? Causes and Care Tips for Trembling Dogs

Dogs communicate with us in various ways, and when they exhibit unusual behaviors, it often raises concern. One such behavior is shaking or trembling, which can range from mild and occasional to severe and persistent. Understanding why your dog is shaking is crucial to determining whether it’s a harmless response or a sign of a serious issue requiring immediate attention.

Common Causes of Shaking or Trembling in Dogs

Shaking and trembling can result from various physical, emotional, or environmental factors. Below are some common causes:

1. Cold Weather: Dogs may shake to generate body heat when exposed to cold temperatures. Short-haired breeds, small dogs, and puppies are particularly susceptible.

2. Fear or Anxiety: Loud noises, unfamiliar environments, or stressful situations can trigger shaking as a physical manifestation of fear or anxiety.

3. Excitement or Anticipation: Some dogs shake when overly excited, such as during playtime or when they anticipate a walk or meal.

4. Pain or Discomfort: Shaking may indicate pain due to injury, arthritis, or internal discomfort. Look for additional signs like whining, limping, or avoiding touch.

5. Illness or Medical Conditions: 

• Canine Distemper: A viral infection that causes trembling along with coughing, fever, and discharge from the nose and eyes.
• Hypoglycemia: Low blood sugar, especially common in small breeds, can lead to trembling, lethargy, and seizures.
• Kidney Disease: Advanced kidney problems can cause shaking due to toxin buildup in the blood.

6. Toxicity or Poisoning: Ingesting harmful substances like chocolate, xylitol, or certain plants can lead to trembling, drooling, and vomiting.

7. Neurological Disorders: Conditions like epilepsy or degenerative diseases can cause uncontrollable shaking or tremors.

8. Old Age: Older dogs may develop tremors due to muscle weakness or age-related neurological conditions.

9. Shaker Syndrome: A condition commonly seen in small breeds like Maltese or West Highland White Terriers, characterized by generalized body tremors.

10. Overexertion or Fatigue: After intense physical activity, your dog may shake due to muscle fatigue or dehydration.

What to Do If Your Dog Is Shaking

When your dog starts shaking, consider the following steps to assess the situation and determine the best course of action:

1. Observe the Context: Identify if the shaking occurs in specific situations, such as during cold weather, after exercise, or in response to loud noises.

2. Check for Other Symptoms: Look for accompanying signs like vomiting, diarrhea, lethargy, or changes in behavior. These may indicate a more serious problem.

3. Provide Comfort: If your dog seems scared or anxious, create a safe, calm environment. Speak softly and offer reassurance.

4. Warm Them Up: If the shaking is due to cold, wrap your dog in a blanket or move them to a warmer area.

5. Avoid Self-Diagnosing: Refrain from administering medications or home remedies without veterinary advice.

6. Contact Your Veterinarian: If the shaking is persistent, severe, or accompanied by other concerning symptoms, seek immediate veterinary care.

How Veterinarians Diagnose the Cause

Your vet will perform a thorough examination to determine the cause of your dog’s shaking. This may include:

• Physical Exam: Checking for injuries, pain, or external signs of illness.
• Blood Tests: Assessing for infections, organ function, or imbalances.
• Neurological Tests: Evaluating reflexes and coordination for signs of neurological disorders.
• Imaging: X-rays or ultrasounds to detect internal issues like tumors or injuries.

• Regular Vet Check-Ups: Routine veterinary visits can help catch potential health issues early.
• Gradual Exercise Routine: Avoid overexerting your dog, especially in hot or humid weather.

When to Seek Emergency Care

Contact your veterinarian immediately if:
