The dog keeps shivering, which may be caused by the cold. In the cold winter, cold air stimulation causes the body to tremble and produce heat, resulting in shivering. It is recommended that dogs be placed in a room with a warm environment.

It may also be caused by fear or nervousness. Generally, puppies are timid. If they enter a strange environment or come into contact with strange people, they will feel scared. You can use food or play with the puppy more to eliminate the puppy's nervousness.
