This condition may be caused by factors such as cold or physical pain and discomfort. First of all, in the cold winter, cold air stimulation causes the body to tremble and produce heat, resulting in shivering. It is recommended to place the dog in a warm room and put soft blankets or old clothes in the kennel. Secondly, if the dog has abdominal pain, trauma, fractures, etc., and the body pain and discomfort cause the body to tremble, it is recommended to consult a doctor for medication.
