Shaking can be normal or a sign that something needs attention. Many dogs shiver when they are cold, especially small or thin-coated breeds after a bath or in cool weather. Warming them up with drying, a coat, or moving indoors often resolves this.

Pain or illness can also cause trembling. Dogs may shake when nauseated, feverish, or sore from injury or arthritis. Neurologic issues, toxin exposure, and low blood sugar in very small or young dogs are other possibilities. Ear infections sometimes cause head shaking or an unsteady appearance that owners describe as shaking.

Anxiety and stress are common causes. Loud noises, vet visits, or separation can trigger whole-body trembling. Some dogs shake with excitement before a walk or meal.

Watch the full picture: appetite, energy, vomiting, limping, head tilt, circling, or sudden behavior change warrant a veterinary visit. If shaking is new, severe, or paired with weakness, collapse, bloating, or trouble breathing, seek urgent care. Your veterinarian can examine ears, check for pain, and recommend tests if needed.
