South Florida man, 60-year-old Hernan Acevedo, credits his recovery to a 9-year old therapy dog named Mesa for his recovery after a serious car crash that left him unconscious for over 20 minutes. He spent over a month at Memorial Regional Hospital South in Hollywood for fractures to his back, shoulder, and pelvis. Despite being unable to take Mesa home, he will always remember her as his unofficial man's best friend. The Golden Retriever is described as the hardest-working therapy dog at the hospital.
