How these dogs saved their humans' lives

In her new book How My Dog Saved My Life, former CBC producer Cate Cochran tells 30 Canadian stories of dogs who have changed everything for their humans, saving their lives literally and figuratively. We'll meet some of these remarkable canines, including a black lab and golden retriever mix named Foreman who's trained to provide medical assistance for his owner, Sinead Zalitach. Sinead was born with an extremely rare congenital condition called Parkes Weber syndrome and Foreman is so attuned to her that he knows she's in trouble before she does.
