More than a companion: The life-changing power of guide dogs

To many, dogs are a man's best friend, but for others, they're a lifeline. Dr. Renatta Varma, ophthalmologist and Chair of the Canadian National Institute for the Blind (CNIB) Guide Dog Gala, joins the show to talk about the life-changing impact of guide dogs and the upcoming gala on May 7. It raises funds and awareness for Canadians who are blind or have low vision.
