Shih Tzus can have various reactions when encountering new noises or unfamiliar sounds. Their response may depend on their individual temperament, prior experiences, and how well they have been socialized. Here's a brief explanation of potential reactions:

Curiosity and Alertness: Shih Tzus are naturally curious and alert dogs. When they encounter new noises or unfamiliar sounds, they may become attentive, perk up their ears, and try to locate the source of the sound.

Barking or Vocalizing: Shih Tzus have a tendency to bark or vocalize when they encounter unusual noises. This is their way of expressing alertness, curiosity, or even a form of mild concern.

Startling or Nervousness: Some Shih Tzus may startle or become nervous when exposed to loud or sudden noises, especially if they haven't been previously exposed to similar sounds during their socialization period.

Seeking Comfort or Hiding: If a new noise or unfamiliar sound is particularly loud or frightening, a Shih Tzu might seek comfort from their owner or find a safe place to hide
