Nevada dog laws: leash, licensing, bites and breed rules

This is a general summary of Nevada state law for dog owners. It is information, not legal advice. Reviewed November 2026.

Leashes and licensing

Nevada has no general statewide leash law. A statute makes it a misdemeanor for a person with the care or custody of an animal known to have vicious or dangerous tendencies to let it escape or run at large in any place or manner liable to endanger a person (NRS 575.020). Other leash and at-large rules come from counties, cities and towns.

Licensing is local. State health rules let a county, city or town require the owner of a dog, cat or ferret to obtain a licence for each animal (NAC 441A.410).

Rabies vaccination

State health rules require each county, city and town to adopt an ordinance that requires all dogs, cats and ferrets in its area to be vaccinated against rabies and lets it cite owners of unvaccinated animals (NAC 441A.410). An owner must keep a dog currently vaccinated according to the national compendium, using a vaccine that gives 3 years of protection. A veterinarian may exempt a dog for health reasons, and an exempt or too-young dog must be confined to the owner's premises or kept under physical restraint (NAC 441A.435).

When a dog bites a person, the rabies control authority must have it quarantined and observed for 10 days following the bite, whatever its vaccination status, in an enclosure or restraints that prevent contact with people or animals (NAC 441A.425).

Dangerous dogs and bites

Nevada has no dog-bite statute, so a civil claim rests on common law negligence principles. The dangerous-dog rules sit in NRS 202.500. A dog is "dangerous" if declared so after being used in a crime, or if, without provocation, it behaved menacingly twice within 18 months in a way that would lead a reasonable person to defend against substantial bodily harm. A dog is "vicious" if, unprovoked, it killed or inflicted substantial bodily harm on a human, or kept up dangerous behavior after its owner was notified by law enforcement. Keeping a vicious dog more than 7 days after notice is a misdemeanor. If a known vicious dog causes substantial bodily harm, the owner commits a category D felony and a judge may order the dog destroyed.

Breed-specific rules

A dog may not be found dangerous or vicious based solely on its breed, and a local authority may not adopt or enforce an ordinance or regulation that deems a dog dangerous or vicious based solely on breed (NRS 202.500).

Tethering and hot cars

A person may not restrain a dog with a tether, chain, trolley or pulley shorter than 12 feet or that does not let the dog move 12 feet, or that lets it reach a fence or object where it could be strangled. A prong, pinch or choke collar may not be used, and a dog may not be restrained for more than 10 hours in 24. Exceptions include leash walking, hunting and training, shows, and some agricultural and temporary uses. A first offense is a misdemeanor (NRS 574.100).

A person may not leave a pet unattended in a parked or standing vehicle if heat, cold or other conditions present a significant risk to it. Peace officers, animal control officers and some other officials may use reasonable means to remove the pet without liability. So may anyone else who finds the vehicle locked, reports it to law enforcement, 911, animal control or the fire department, stays close by until told to leave, and cooperates with responders (NRS 202.487).

Where to check your local rule

Counties, cities and towns often set stricter leash, licence, number-of-dogs and noise rules. Check the local animal control website or ordinance code. If a dog has bitten someone or been reported, talk to a lawyer or the animal-control office.
