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

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

Leashes and licensing

Mississippi has no statewide leash law and no statewide dog licence. The state instead gives local governments the power. The governing authorities of a municipality may prevent or regulate the running at large of animals of all kinds, have loose animals impounded, tax and regulate the owners and harborers of dogs, and destroy dogs running at large unless they have identification showing a rabies vaccination (Miss. Code 21-19-9). A short list of named counties holds similar powers (Miss. Code 19-5-50). Leash, licence and fee rules therefore depend on your city or county.

Rabies vaccination

State law makes it unlawful to own or possess a dog or cat 3 months of age or older that has not been vaccinated against rabies with a vaccine approved by the State Board of Health. The owner must have the dog vaccinated right after it reaches 3 months. A licensed veterinarian or another person with a Board of Health permit must give the shot, and the dog must wear a metal tag showing the vaccination serial number and year. The vaccinator gives the owner a certificate (Miss. Code 41-53-1 to 41-53-9). Officers may impound loose dogs without a collar and tag and must hold them five days before any other step (41-53-11). Violations are misdemeanors with small fines (41-53-13). The state's current rabies guidance calls for a three-year vaccine.

State health rules say a healthy dog, cat or ferret that bites a person shall be confined and observed for 10 days in a manner acceptable to the local health officer. A stray or unwanted dog that bites may be euthanized in place of the observation, and its head tested.

Dangerous dogs and bites

Mississippi has no dog-bite statute and no statewide dangerous-dog law. Civil claims for a bite generally rest on common law, which in this state has followed the one-bite approach, where an injured person must usually show the owner knew or should have known of the dog's dangerous tendency or was negligent.

Several statutes cover damage to animals and serious outcomes. An owner of poultry or livestock may kill a dog in the act of chasing or killing the animals, and a dog owner must pay for loss when a dog kills or injures poultry or livestock (Miss. Code 95-5-19 and 95-5-21). If the owner of a mischievous animal, knowing its propensity, willfully lets it go at large, or keeps it without ordinary care, and it kills a person who took reasonable precautions, the owner is guilty of manslaughter (Miss. Code 97-3-45).

Breed-specific rules

The state dog statutes reviewed contain no breed-specific rule. Any breed rule you meet is likely to come from a city or county.

Tethering and cruelty

Mississippi has no statewide tethering law. The general cruelty laws still apply to neglect or harm.

Aggravated cruelty to a domesticated dog or cat, meaning malicious torture, mutilation, maiming, burning, starving, crushing, disfiguring, drowning, suffocating or impaling, is a felony. A first offense can bring a fine up to $5,000 or up to 3 years in prison, or both. A second or later offense within 5 years can bring 1 to 10 years. The court must bar a person convicted of aggravated cruelty from owning or living with a dog or cat for 5 to 15 years (Miss. Code 97-41-16).

Where to check your local rule

Cities and counties often set leash, licence, number-of-dogs, vicious-dog and breed 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.
