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

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

Leashes and licensing

Minnesota has no general statewide leash law. State law expressly leaves it to municipalities to prohibit, license or regulate dogs running at large (Minn. Stat. 347.21), so leash rules differ from city to city.

Licensing is also mainly local. A set of county provisions says that in any county where they are in force, every dog more than 6 months old must be licensed each year (Minn. Stat. 347.09). Many cities and towns require licences by ordinance. Ask your city or county what applies.

Rabies vaccination

State rules from the Board of Animal Health say a dog, cat or ferret that bites a human must be kept under confinement and observed for signs of rabies for ten days, or euthanized and tested for rabies (Minn. R. 1721.0580). Ask your veterinarian or local animal control what vaccination and quarantine arrangements apply where you live.

Dangerous dogs and bites

On the civil side, if a dog without provocation attacks or injures a person acting peaceably in any place where the person may lawfully be, the owner is liable in damages for the full amount of the injury. "Owner" includes anyone harboring or keeping the dog, though the owner is primarily liable (Minn. Stat. 347.22).

Minnesota's dangerous-dog statute works through local animal control authorities. A "potentially dangerous dog" is one that, unprovoked, bites a human or domestic animal, chases or approaches a person in an apparent attitude of attack, or has a known propensity to attack unprovoked. A "dangerous dog" has, without provocation, inflicted substantial bodily harm on a person or killed a domestic animal off the owner's property, or has attacked after being found potentially dangerous (347.50). An owner may not keep a dangerous dog unless it is registered, which requires a proper enclosure and warning sign, a bond or liability insurance of at least $300,000, a microchip and an annual fee of up to $500 (347.51). Outside the enclosure the dog must be muzzled and on a substantial chain or leash held by a responsible person, and it must be sterilized (347.52). A dog is not to be declared dangerous if the person was committing a trespass or other tort or a crime, or was provoking or abusing it. After a hearing, the authority may destroy a dog that inflicted substantial or great bodily harm, multiple bites or bit several victims in one attack, all without provocation (347.56). Violations are misdemeanors, rising to gross misdemeanors for repeat violations (347.55).

Breed-specific rules

A statutory or home rule charter city, or a county, may not adopt an ordinance regulating dangerous or potentially dangerous dogs based solely on the specific breed of the dog, and inconsistent ordinances are void (Minn. Stat. 347.51).

Tethering and hot cars

Minnesota has no statewide law on tethering dogs, although the general animal cruelty law requires owners to provide food, water and shelter (Minn. Stat. 343.21).

A person may not leave a dog or cat unattended in a standing or parked motor vehicle in a manner that endangers its health or safety. The penalty is a $25 fine. Peace officers, humane agents, dog wardens and volunteer or professional fire and rescue members may use reasonable force to enter the vehicle and remove the animal (Minn. Stat. 346.57). The statute does not give that power to other people.

Where to check your local rule

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