Every year canines with mugs only their mothers could love converge in Petaluma. Their mission? To compete in the World’s Ugliest Dog Contest. The subject of national media attention, the popular spectacle is an annual part of the Sonoma-Marin Fair. It’s one of a variety of events—including daily funnel cake–eating and whipping cream contests and live music performances by the likes of Loverboy, Sammy Kershaw, and others—that the fair is offering for free with admission. For an extra fee, attendees can also experience sprint car races and wine tastings. The fair is set to run June 19–23 at the fairgrounds in Petaluma. Gates will be open noon–11 p.m. on June 19 and 20, noon–midnight on June 21 and 22, and noon–11 p.m. on June 23. The Ugliest Dog Contest will be held on June 21 at 6 p.m. General admission is $12–$18 at the gate, and $10–$15 in advance, and includes unlimited rides. (On June 19 all tickets will be $12 before 5 p.m.) Sprint car races and wine tastings are an additional $10–$15. Find out more and purchase tickets at sonoma-marinfair.org.
