Why do shih tzus lick open wounds?

Shih Tzus, like many dogs, may lick open wounds as a natural instinct to clean and soothe the area. Their saliva contains enzymes that can help with healing and may provide temporary relief from pain or irritation. However, excessive licking can lead to further irritation or infection, so it's important for pet owners to monitor their dog's behavior and consult a veterinarian if needed. Additionally, stress or anxiety can also prompt this licking behavior.
