Dogs have a long history of being man’s best friend. But the story of a Newburyport Police Department officer and her blind dog from Massachusetts, doesn’t merely prove the bond between owner and pet but also proves that dogs are great at detecting illnesses.
Police officer Megan Tierney was reportedly at home with Dude, her blind border collie/Australian shepherd mix, when he started acting a little strange. According to her, she was lying in bed when Dude suddenly became focused on her chest area, placing a paw on her.
Tierney turned her attention on the spot Dude was touching and noticed a tissue swell. But to her surprise, a trip to the doctor confirmed that she has stage two triple negative invasive ductal breast cancer. And although finding out you have cancer is never an easy thing to swallow, the police officer said, “Dude found the lump, and we were never so happy because it just meant that we could get it where it was, rather than not knowing.”
It is known that dogs have a more heightened sense of smell compared to humans. Dude, being a blind dog, has greatly enhanced this particular sense which helped him detect the illness of his owner. Moreover, canines’ olfactory bulbs have 220 million scent receptors; 195 million more than that of humans.
According to dog-cognition researcher Alexandra Horowitz from Barnard College, dogs can smell odors in parts per trillion. For example, in a million gallons of water, dogs can detect if a teaspoon sugar was mixed into the water. This means their smelling abilities are 100,000 times better than ours.

One study, conducted by the Pine Street Foundation, reflects Dude’s exceptional skill. The study involved five dogs that were given breath samples of 31 breast cancer patients, 55 lung cancer patients and 83 healthy persons. All dogs were able to pinpoint which samples came from those who were ill, with approximately 90 percent accuracy.
Can dogs really smell cancer?
According to Tammana Khare of Dogs Naturally Magazine, because of the metabolic waste released by cancerous cells, a distinct smell is also released from the human body. This significant smell can be easily traced by dogs even during the earlier stages of cancer.
Other studies suggest that canines also have the ability to smell traces of skin cancer melanoma through skin lesions, and detect prostate cancer with just a urine sample from a person who is suffering from one.
“Not only does their sense of smell make cancer detection possible, but research suggests that dogs can be trained actively to sniff out the cancer, ” the canine expert shared. “In Berlin, a group of researchers trained some dogs to detect the presence of various types of cancer, including ovarian cancer, bowel cancer, as well as bladder cancer, skin cancer, lung cancer and prostate cancer,” Khane finished.
Although some remain to be with the whole idea of dogs being able to sniff out cancer and other illnesses, there are already some field experts who see a future where dogs will be directly used in patient care. More importantly, the special dog ability Dude exhibited helped his owner, Tierney, to manage her sickness and prolong her life.
