Why Is My Dog Constantly Shivering

Shivering 📅 August 7, 2026 👁 5690

📝 Summary

Constant shivering in dogs can signal fear, cold, poisoning, or illness. A scared or cold dog needs comfort and warmth; poisoning (from plants like morning glory or cleaners) brings foaming and stiffness and needs emergency vet care; underlying disease such as distemper, epilepsy, or kidney failure also causes trembling. If the cause is unclear, see a vet.

1 Why a Dog Keeps Shivering and What to Do

1. Fear and anxiety

In an unfamiliar place a dog may shake from fear — loud thunder works too — and show restlessness. Stay with it, comfort it, and keep a familiar item nearby until it settles.

2. Low temperature

Shivering can simply be cold: the dog generates heat to stay warm. In cold weather keep it warm and sheltered; post-bath winter shivering is common, so consider a heater to avoid chills and colds.

3. Poisoning

Constant shaking may mean it ate something toxic — morning glory, castor bean, chemical cleaners — and it will also foam at the mouth, have seizures, and stiffen. Take it to a vet at once to identify the poison and whether inducing vomiting is needed, before it worsens or kills.

4. Feeling unwell

Shivering can also mean illness — wounds, canine distemper, epilepsy, nerve damage, chronic kidney failure. If you can’t find the cause, go to a vet for checks and treat under guidance.

A gentle reminder: shivering can also come from calcium deficiency, over-excitement, or poor digestion. If unsure, consult a veterinarian or take the dog in for an exam.
