You probably won't gain fame and fortune by becoming a pet sitter, but you might find a way to wangle at least your 15 minutes of fame. First, how many dogs can you walk at one time? Five? Ten? As many as you can string together? You might get a photo in the local newspaper, and perhaps even a brief appearance on your city's evening news as a human interest story, if you can manage this feat without losing any pooches (or fingers). Pet sitters in celebrity hotspots, such as Los Angeles and New York City, often gain a reputation by walking the frou-frou dog breeds owned by publicity-hungry performers. On the down side, you might find it tough to get your first celebrity gig if you're not hooked into the "famous person" service market. You may also get hooked into the "famous dog" service market, but Lassie and Rin Tin Tin aren't in a position to be taking on clients these days.
