Many owners notice their small dogs tremble more frequently. This phenomenon is often linked to thermoregulation, where smaller dogs lose heat faster due to a higher surface-area-to-volume ratio. Consequently, they expend more energy to maintain core body temperature, making them more susceptible to feeling cold.
Beyond cold, stress, fear, certain medications, and neurological conditions such as idiopathic generalized tremor syndrome can induce shivering. Owners should observe environmental factors, a dog's stress signals, and consult a veterinarian if trembling is persistent or concerning, as it can indicate underlying health issues or anxiety that require management.
