The pet business is booming...for good and for bad. I loved talking to Dana Dubriwny about it because she is really at the pulse of it with her dog-walking and pet-sitting business Chicago Pet Sitters. Leaving your pet in the care of someone else is stressful and she has created a business that helps ease worries, but it can also be very stressful for her. It was a great conversation, with a side of Richard Branson.
