We meet dogs who detect cancer and Parkinson's disease, and dogs who alert people to seizures and diabetic lows or highs and other life-threatening physical ailments. Goodavage reveals the revolutionary ways dogs are helping those with autism, anxiety, depression, schizophrenia and post-traumatic stress disorder. And she introduces us to intrepid canines who are protecting us from antibiotic-resistant bugs, and to dogs who may one day help keep us safe from epidemic catastrophe. Their paycheck for their lifesaving work? Heartfelt praise and a tasty treat or favourite toy. The emotional element in Doctor Dogs delivers as powerfully as the science. You don't have to be a dog lover to care deeply about what these dogs are doing and what we are learning from them, although if you're not a dog lover, you probably will be by the end of the book.
