More: Diego is my son’s service dog. He and my son were in a rollover, fatal accident, on a Xmas eve. My sons fiancé was the fatality. Diego is helping my son through the grief. He is loyal, loving, playful, smart, sassy and fearless. Having Diego to walk, play ball, take a hike, or just sit and watch the sunrise, is enough. He helps my son, emotionally, physically, spiritually. He’s family.
