2025 Vet Guide: Why Does My Dog Shake? Causes, Care & When to Worry 🐶

By Dr. Duncan Houston BVSc

Hi, I’m Dr Duncan Houston BVSc, veterinarian and founder of Ask A Vet. Seeing your dog tremble or shake can be unsettling. Often it’s harmless, but sometimes it signals pain or serious illness. In this 2025 guide, we uncover common and serious causes, share expert home-care tips, and outline when to head to the vet.

1. Common Harmless Causes

1.1 Excitement & Joy 🎉

Dogs often shake when they’re thrilled—like greeting you or playing. It’s usually brief and harmless.

1.2 Cold & Wet Exposure ❄️

Shivering is the body’s way of warming up. Small breeds or short-coated dogs feel it more strongly.

1.3 Post-Stress “Shake-Off” 🧠

After scary events—veterinarian visits, storms—dogs instinctively shake to reset. It’s normal and often helpful.

2. Signs of Stress, Fear & Anxiety

Trembling can reflect mental or emotional distress:

• Stress or fear: fireworks, vet trips, unfamiliar situations
• Separation anxiety: accompanied by pacing, whining, and excessive trembling

2.1 Reducing Stress & Anxiety

• Calm routines and safe zones (crate or quiet room)
• Use pheromones (via Purrz) and calming tools
• Desensitize to triggers gradually with treats
• Find expert support on the Ask A Vet app

3. Pain, Illness & Medical Causes

3.1 Pain or Physical Discomfort

Shaking can be a red flag for pain—injuries, arthritis, internal illness.

3.2 Medical Conditions

• Endocrine disorders: Addison’s disease (low cortisol) or hypoglycemia
• Neurological issues: tremor syndromes, cerebellar disease, seizures
• Infections or toxins: distemper, poisoning—a medical emergency
• Ear problems: shaking head from infection or irritation

4. When Is Shaking an Emergency?

Worry and act fast if shaking is:

• Uncontrolled or lasts > minutes
• Accompanied by collapse, vomiting, pale gums, seizures, difficulty breathing
• After ingesting toxins

If these signs appear, seek emergency vet care immediately.

5. Supporting Your Dog at Home

5.1 Warmth & Drying

Move cold or wet pups indoors, offer blankets, and consider a doggy coat for chilly days.

5.2 Comfort During Stress

Offer reassurance, puzzle toys from Woopf, or calming chews from Purrz. The Ask A Vet app can help create a de-stress plan.

5.3 Observe & Document

• Note frequency, duration, patterns, and triggers
• Record symptoms like appetite loss, pain, or behavior changes
• Share this info during vet consultations

5.4 Veterinary Diagnosis & Treatment

Your vet may conduct physical exams, blood tests, hormone panels, neurological assessments, or imaging to identify causes. Treatment may include medications, dietary adjustments, or pain management plans.
