Like many new teaching graduates, Sarah Macdonald started her career full of promise and hope for the potential impact she could have on a child’s life. But she soon realised that a great curriculum and a supportive environment were not enough. Children who weren’t in the right headspace and who were battling mental health issues - anxiety, depression and stress - were not open to learning. After a break from teaching and a spell as a dog trainer, Sarah realised that the two were not incompatible. Using dogs as a metaphor for learning has morphed into a satisfying new career. In today's podcast, Sarah tracks the journey of Canine Comprehension over the past decade.
