Woofstock is North America's largest festival for dogs. Boasting over 200,000 annual attendees and 250 vendors and exhibitors, Woofstock is both a non-stop, weekend long outdoor dog festival and a consumer expo. In 2010, Woofstock launched a winter event, giving pet industry entrepeneurs and dog lovers another chance to play and network each year. Woofstock's creator, Marlene Cook, recently made an appearance on The Dragons' Den. No firm deal has been reached.
