Should I go to the emergency vet?

Go now if the shaking comes with collapse, a swollen belly, pale gums, or a toxin exposure such as chocolate, xylitol, or a medication dropped on the floor. A small dog that shivers when cold and then stops is a different story.

How much will treatment cost?

The exam looks for pain, a fever, and a source such as a back injury, nausea, or low blood sugar in a tiny or young dog. Bloodwork is added when the shake does not match a simple chill. Ask before the panel is run.

Can I treat this at home?

Warm a cold small dog and note whether the shaking is localized to a painful spot. Never give ibuprofen, naproxen, or acetaminophen. Write down anything the dog could have eaten in the last hour.
