Dogs are called man’s best friend for good reason. They have served with distinction in the military, sniffed out bombs and been caring companions to people with disabilities.

New research now pinpoints advances in the use of dogs to diagnose human diseases and help solve environmental problems.

Dr. Cindy Otto, of the University of Pennsylvania’s Working Dog Center, notes that some diseases and bacteria have a special odor, which dogs can smell. Medical studies in Europe have shown that some dogs can even pinpoint people with cancer.
