Does anyone have a clue what happened to my chihuahua? I found this red circle looking bruise on her, does anyone know what it could be? Should I be concerned? Extra points for a good explanation

Personality is a mixture of characteristics/qualities that form an individual's distinctive persona. it can be influenced by environmental and biological factors; one's culture is a most important factor that shape personality. extreme mood swings, unstable relationships, distorted self-image, impulsive/risky behavior, explosive anger, chronic feelings of sadness/emptiness, etc. these could indicate that someone could have a personality disorder.
