Carrie Underwood had a tragic family accident this Christmas, one of her two dogs was paralyzed just before the holidays with a herniated disc. The country star recently posted on Instagram a video of the dog in a physical therapy in a swimming pool walking with the help of a therapist writing on Instagram, "my little ace got his mobility back in his right side. His left side is slowly getting better, but we have a long way to go."
