Cleverly costumed canines march a parade route to celebrate Halloween at this special event dedicated to dogs! Activities include a costume contest, juging and an awards ceremony. Spectators are welcome too! Nonprofits and vendors from a variety of local pet supply shops will share information and sell dog-related products. The parade steps off from the Esplanade, where the activities and costume contest take place. Dogs must be on leash at all times and must leave the Garden by 2 p.m.
