Victor Calderone was recently diagnosed with cancer, which he caught early, thanks to a four-legged furry friend.

The New York City-born DJ, 54, announced the news on Instagram Monday, after his dog Tuco was able to detect his cancer and trigger a symptom, sending him to the emergency room. "I never imagined the immense love I would develop for Tuco and how he would change my world as I know it," Calderone wrote on Instagram.
