Life in a Dog's Nose: The Miracle of Early Diagnosis

Inca’s Unusual Behavior Saved a Life

When the German Shepherd, Inca, began obsessively sniffing her owner’s breath, Ferguson didn't suspect anything at first. However, the dog’s anxious behavior and the way she would sit just millimeters from Ferguson’s face upon waking caused her to take the situation seriously. Even though routine blood tests came back clear, the veterinarian decided to get a full-body scan, refusing to ignore her dog’s persistent "warnings."

As a result of the scans, Ferguson was diagnosed with stage one lung cancer. For Ferguson, a non-smoker who only complained of slight fatigue, surgeons made this striking statement: "Detecting cancer at this stage is nearly impossible. Your dog saved you."

After a golf-ball-sized mass was removed from her left lung, Ferguson regained her health without needing chemotherapy or radiotherapy, thanks to the early detection. Today, continuing her life as a successful author, Ferguson expresses at every opportunity that she owes her success to her loyal friend, Inca.
