Frequently asked
Why is my dog shaking but acting normal?
Cold, excitement, or anxiety (e.g. fireworks) are common harmless causes. If shaking persists, comes with other symptoms, or follows possible toxin exposure, see your vet.
Can shaking be a sign of poisoning?
Yes — tremors can indicate toxin exposure. If your dog may have eaten something toxic and is trembling, treat it as an emergency.
