Why Is My Dog Shaking or Trembling?
Shaking can be completely normal — a cold, excited or nervous dog trembles. It can also be a sign of pain, nausea, low blood sugar or poisoning. Context matters.
Common causes
- Cold — small, short-coated breeds especially
- Fear or anxiety — storms, fireworks, vet visits
- Pain — back, joints, belly
- Nausea
- Old-age tremors in the back legs
- Toxins — chocolate, caffeine, xylitol, certain medications
See a vet today if
- Shaking with vomiting, weakness, or collapse
- Possible exposure to a toxin
- Seizure-like movements or loss of awareness
- Shaking with obvious pain or a hunched back
