"Dog Park" has two love affairs, two mysteries, a political protest and lots of laughs. It is a humorous tale about the small town of Rexville, its wacky, but good-hearted, citizens and its prized _ you guessed it _ dog park. Robert Benjamin is a stay-at-home accountant who realizes his life is in shambles because he loves dogs too much. His therapist, Jen Giolito, views Robert as her ticket to psychological stardom. Andy Kershaw has ambitions too. He sees his job as top dog catcher as his last chance to join human law enforcement _ if he can just catch the person who is not curbing his dog. Gladys Ridgeway runs a dog salon, and she thinks she runs the dog park. Her intrusiveness gets Robert into a lot of trouble with town police chief Neal Zook. Robert turns for help to other dog owners who gumshoe their way through the internet to solve the case. The wackiness all culminates in Rexville's annual dog show. Westminster, it is not. But it does attract media personalties and a big-city TV reporter, who tells her anchor, "All the good stories happen in small towns like Rexville."
