White Dog Shaker Syndrome

Condition Overview

This syndrome occurs primarily in adult dogs with white coats, although dogs with other coat colors are occasionally affected. The disease occurs most often in small breeds, including West Highland White Terriers, Maltese, Bichon Frises, and Toy and Miniature Poodles.

Symptoms

It is characterized by the sudden appearance of tremors, sometimes accompanied by wild and random movements of the eyes. The disease affects the cerebellum, which coordinates muscle movement. Sudden trembling that involves the entire body and head is the main sign. The dog does not shake while sleeping, but the more she moves, the worse the tremor gets. These tremors can be disabling.
