It didn't go well.
His owner, Dayna Denman, got a call that day from her neighbor. Rex had been badly mauled.
"He was found lying and bleeding badly in the middle of thick bush by my neighbor who brought him some blankets and sat with him until I got there," Denman wrote in a Facebook post.
Denman rushed to the scene. Despite his grave condition, Rex managed to stir when he heard her voice.
Rushed to the hospital, Rex began a long road to recovery.
