It is Multnomah County law to have your dog on a leash at all times while in Portland parks and public spaces. The only exception is if your dog is inside a designated off-leash area. The purpose of the leash law is to ensure that dogs are kept under control at all times while in the park to ensure the safety and enjoyment of all park visitors, and to protect the park's environment and wildlife. Keeping your dog leashed is also the best way to keep your dog safe from hazards which could injure or even kill it. Additionally, other park visitors may not want to meet your dog, particularly if they are accompanied by a child, if they are afraid of dogs, if they are elderly or if they are accompanied by a leashed dog.
