Hayward Dog Leash Laws Rules (2026): What You Need to Know

Hayward Municipal Code Chapter 6 establishes a comprehensive leash and at-large framework for dogs within the city's approximately 64 square miles and population of roughly 163,000 residents. The code defines a dog as "running at large" when it is off the premises of the owner and not under the immediate control of a competent person by means of a substantial leash, cord, or chain not exceeding six feet in length. This definition applies on all public property including streets, sidewalks, parks, trails, parking lots, and common areas of multifamily complexes.

The six-foot maximum leash length is strictly enforced in all city parks, along the San Lorenzo Creek Trail, and on city-maintained open space parcels in the Hayward Hills. Retractable leashes are permitted only when locked at or under six feet; a retractable leash extended beyond six feet does not satisfy the code's restraint requirement. Dogs must be physically held by a person capable of controlling the animal — tying a leash to a stationary object such as a tree, bike rack, or bench while the owner is not present does not constitute compliance and the dog may be deemed at large.

Hayward Animal Services, operated by the City of Hayward, is the primary enforcement agency for leash and at-large violations. Officers patrol city parks, trails, and neighborhoods and respond to at-large complaints filed by residents. Dogs found running at large are subject to impoundment at the Hayward Animal Shelter located at 16 Barnes Court. Owners may reclaim impounded dogs upon payment of impound fees, daily boarding charges, and any outstanding licensing fees. All dogs four months of age and older must be licensed with the City of Hayward and must have a current rabies vaccination on file.

Voice control alone does not satisfy the leash requirement on public property. Even well-trained dogs must be physically restrained by a leash when outside the owner's enclosed private property. The leash requirement is especially important along the Hayward shoreline and around Hayward Regional Shoreline, where dogs off-leash can disturb protected shorebird and waterfowl habitat managed by the East Bay Regional Park District. Within East Bay Regional Park District lands, the District's own leash regulations apply and are enforced by Park District rangers.

Residents may report dogs running at large to Hayward Animal Services at (510) 293-7200 during business hours or to the Hayward Police Department non-emergency line at (510) 293-7000 after hours.
