Professional poop scooper and founder of the Association of Professional Animal Waste Specialists, Tim Stone, once said he earns a not-too-shabby $76,900 (£56k) per year picking up dog mess. He removes canine poo from gardens in upscale Santa Clarita, California. In 2003, Tim wrote a book, The Professional Scoop Master - A Guide to Starting and Running Your Own Dog Poop Pick Up Service, to help other budding entrepreneurs get into the business.
