Even though dogs do not communicate with human language, you can still pick up clues of their mood. For the most part, you can notice some warning signs of a dog ready to bite. Canines tend to growl or snap at people or other animals before they attack.
Usually, the visibility of teeth means to back away slowly. The growls could indicate a sense of discomfort. The discomfort could be due to physical pain or anxieties. Pets need some space and time to calm down. With stray dogs, people might need to avoid their territory if possible.
If a dog licks their lips despite the lack of food, it could be a warning sign. Some of them will yawn if they are prepared to bite. Others may avoid your gaze to indicate they do not feel comfortable.
While some canines will avoid eye contact, others will keep eye contact but turn their head away. As a result, the sclera, or the white part of the eye, becomes visible. The tail may move in a quick, rigid motion or remain tucked between the legs as well.
