Question: my shih tzu has started shaking?
Answer: Generalized Tremor Syndrome Generalized Tremor Syndrome is quite common in small breeds like Shih Tzus, Miniature Pinschers, and Chihuahuas. Also known as Shaker Syndrome, this issue is characterized by full-body tremors, much like the dog is cold. This generally will show up in adolescence, but may get worse with age.
