However, I can provide you with some information about why dogs might bite and what to do if you are bitten:
* Reasons for dog bites: Dogs may bite for various reasons, including fear, pain, protection of their territory, or as a reaction to improper handling.
* Preventing bites: It's essential to train your dog properly, socialize them, and manage their environment.
* If bitten: If you are bitten, seek medical attention immediately.
If you have concerns about your Shih Tzu's behavior, please consult a professional dog trainer or veterinarian. They can help you understand your dog's behavior and develop a plan for managing potential bite risks.
