I first met Katie in my Friday yoga class. She’s a little hard to miss since she’s the only yogi in the class who brings her dog with her. I soon came to find out that she works as a volunteer raising companion dogs as well as therapy dogs. I was immediately fascinated, not just by her work with dogs, but I had a million questions about the relationship between dogs and humans, why dogs are so good at reregulating us and why so many people regard them as man’s best friend.
