Why do Chihuahuas shake so much?

Chihuahuas shake for a combination of physical and emotional reasons, often due to their small body mass and high metabolism which makes them susceptible to cold. They also exhibit heightened anxiety and can shake when overstimulated, fearful, or experiencing separation anxiety, reflected in their low social intelligence score of 1/5. This breed's high memory score of 4/5 means they can also remember past negative experiences, contributing to stress-induced shaking.
