Los Angeles County Dog Leash Laws Rules (2026) — What You Need to Know

Los Angeles County's animal control laws under Title 10 are comprehensive and strictly enforced by the Department of Animal Care and Control (DACC). The core leash requirement is straightforward: all dogs must be restrained on a leash no longer than 6 feet whenever they are outside their owner's property. This applies on sidewalks, in parks (unless posted as off-leash), on trails, and in all public areas.

Licensing is mandatory for all dogs and cats over 4 months of age. Licenses require proof of current rabies vaccination. The county offers reduced license fees for spayed/neutered animals, which also serves as an incentive for compliance with the mandatory spay/neuter ordinance.

Section 10.20.350 is one of the most significant animal control provisions: mandatory spay/neuter for all dogs and cats. Exemptions exist for licensed breeders, law enforcement animals, service animals, and animals with documented health conditions that make surgery risky. Owners who fail to comply face a $250 infraction for the first offense. Subsequent violations escalate to misdemeanor charges carrying fines up to $1,000 and up to six months in jail.

Microchipping is required for all dogs and cats at the time of licensing or adoption. The county charges $7.50 for the microchip. If an unlicensed animal is found at large and impounded, the owner faces a $40 field enforcement fee on top of standard impound and boarding charges. DACC operates seven animal care centers across the county and maintains a 24-hour emergency response line.
