What causes a Shih Tzu to shake?

Shih Tzus might shake a natural response to cold temperatures, excitement, fear, anxiety, or even happiness. Sometimes, shaking could indicate pain or health issues, so it’s essential to observe and seek veterinary advice if the shaking becomes frequent or out of the ordinary. If the shaking is continuous or associated with other symptoms like weakness, appetite loss, or unusual behavior, it’s crucial to consult a vet to rule out any underlying health concerns.
