The video doesn't provide details about what happened to Priscilla before she was rescued But it is understood that, she was abused for most of her life up until she was rescude, and was understandably terrified of humans.
She is so scared but later Priscilla realizes that she is being treated with love, not malice, and warms up to the attention.
Later in the video, Priscilla can be seen happily playing with other humans and dogs. This video shows how adopting a dog can change their lives, a unbelievably wonderful transformation of this amazing dog.
