(Portland, OR) -- After two years of virtual celebrations, the Oregon Humane Society's Doggie Dash returns to Waterfront Park this year. Doggie Dash is the largest celebration of people and pets on the West Coast and the biggest fundraiser of the year for the Oregon Humane Society. It'll be held Saturday May 14th. Some changes have been made, because of the pandemic. The traditional pancake breakfast has been replaced with individually wrapped items. There will be two Libation Stations, so people can spread out. And there will be more waves of start times. Registration is free if you do it before April 30th at doggie dash dot org.
