Full Breakdown

Multnomah County Code § 13.305(B)(1) makes it unlawful for an owner or keeper to permit a dog to be an 'animal at large.' Section 13.002 defines that: on the owner's premises the dog must be physically confined from reaching public areas, and off the premises it must be on a leash, tether or other physical control device no more than eight feet long, under the control of a capable person. Multnomah County Animal Services enforces the rule. This chapter covers unincorporated Multnomah County; Portland, Gresham, Troutdale, Fairview and Wood Village enforce their own animal codes, not this one.
