A dog's body shivering may be caused by cold, fear, pain or calcium deficiency. When the dog has this kind of situation, the owner should pay attention to observation, comfort and pet the dog appropriately to help relieve the mood. If it does not improve, take it to the hospital immediately. During the examination and treatment at the pet hospital, the dog's diet should be adjusted, nutritional supplements should be strengthened, and when the temperature is low, the dog should be kept warm to avoid catching a cold.
