Yes, dogs can smell cancer as well as low blood sugar.
The Pine Street Foundation, a cancer-education and research center in San Anselmo, California, published a study showing it was possible to train dogs to identify, based on breath samples, which patients had lung and breast cancer. Now the organization is recruiting ovarian cancer patients and dogs for a new study.
In diabetics, the presence of ketones—substances made by the body during the metabolic process—can be smelled in urine and on the breath when blood sugars are high. Dogs can pick up on other smells that humans can’t when glucose levels drop.
Pretty amazing, wouldn't you agree?
