Why Do Dogs Shake? Vet‑Approved 2025 Insights & Responses🩺🐶

By Dr. Duncan Houston BVSc

Seeing your dog shake can bring to mind anything from playfulness to panic. But not all trembling is the same! Here's a vet‑approved guide to the most common reasons—and when to take action. 🩺

1️⃣ Shake‑Off (Water or Dust)

Dogs efficiently shake to dry off—70% of water can be shaken from the coat within seconds. It's instinctual and usually follows swimming or bath time.

2️⃣ Cold or Chills

Shivering generates body heat. Common in smaller breeds, puppies, seniors, or after being in the cold.

3️⃣ Excitement or Frustration

Dogs often tremble when overly excited—like when anticipating treats, play, or your return home.

4️⃣ Stress, Fear, or Anxiety

Adrenaline-induced shaking can occur during storms, vet visits, or around strangers. It's a physical stress release.

5️⃣ Itching or Discomfort (Localized Shake)

Head‑shaking often signals ear infections, mites, or irritation and needs examination.

6️⃣ Pain or Injury

Systemic or localized tremors—especially with limping, whining, or behavioral changes—may indicate pain.

7️⃣ Aging & Neurological Changes

“Senior shakes” may reflect aging, muscle loss, cognitive decline, or mild neurological decline.

8️⃣ Medication Side Effects

Some drugs may cause tremors or shakes—always review side effects with your vet.

9️⃣ Underlying Medical Conditions

Conditions like cerebellar disorders (“shaker syndrome”), Addison’s, hypoglycemia, distemper, or seizures often include tremors.

🔟 Poisoning or Toxins

Exposure to toxins (e.g., chocolate, xylitol, plants, pesticides) may cause severe tremors and emergency symptoms like pacing, or incoordination—this requires immediate vet care.

📊 Quick Diagnosis Guide

🔍 Final Thoughts

Shaking is common—and often harmless—but pay close attention to patterns, body signals, and context. When shakes are unexplained, repetitive, or accompanied by other symptoms, seek veterinary evaluation to ensure your dog’s well-being. 🐶❤️
