No specific state law
Mississippi has no state law specifically about animals left in parked vehicles. Leaving a pet in a dangerous car can still be prosecuted as animal cruelty, and some cities have their own ordinances — if you see an animal in distress, call 911.
Yes. Mississippi requires dogs and cats from 3 months of age to be vaccinated against rabies. Boosters follow the vaccine used (usually every 1 or 3 years).
What the law says: It shall be the duty of every person in this state so owning or having in his or her possession a dog or cat to have said dog or cat inoculated (vaccinated) immediately after said dog or cat has reached the age of 3 months, and it shall be said person's further duty to have said dog or cat so inoculated (vaccinated) thereafter as required by the state board of health. Miss. Code Ann. § 41-53-1
Mississippi has no state law stopping cities and counties from banning or restricting dogs by breed. Whether a breed is restricted depends on where you live — check your city or county ordinances before moving with a pit bull–type or other targeted breed.
Mississippi has no dog-bite strict liability statute. Under the “one-bite” rule and negligence law, an injured person usually has to show the owner knew — or should have known — the dog was dangerous, or was careless in controlling it.
Mississippi has no specific provision for pets in protective orders. Judges can often add other conditions they consider necessary, so ask the court or a domestic-violence advocate to include your pet.
Mississippi has no statewide ban on pet stores selling dogs and cats. Some cities and counties have their own bans — check locally before buying from a store, and ask where the puppy came from.
Not for pets travelling with their owner. A health certificate is needed for pets entering for sale, adoption or exhibition, or travelling without their owner. Dogs and cats 3 months and older need a current rabies vaccination.
As summarised by the AKC (March 2023) — confirm with the state veterinarian before you travel:
CVI required.
Must show the dog is free from all contagious and infectious diseases and recent exposure thereto.
Dog must not have originated in an area under quarantine for rabies, or exposed to rabies.
Dogs must be properly vaccinated against rabies within 6 months prior to entry.
Dogs and cats under 3 months of age may be admitted without a rabies vaccination.
Dogs, cats, and ferrets for exhibition, change of ownership, adoption or unaccompanied by owner, must have an official Certificate of Veterinary Inspection issued by an accredited veterinarian with the following compliance:
Apparently healthy and free from all contagious and infectious diseases and recent exposure thereto.
Did not originate within an area under quarantine for rabies, or exposed. Dogs, cats, and ferrets accompanied by owner (not for purposes of exhibition, change of ownership, adoption etc.) are not required to have a Certificate of Veterinary Inspection.
Mississippi has no statewide dog licensing requirement — counties and cities set their own. Most require a licence with proof of rabies vaccination, so check with your local animal services or clerk.
Mississippi has no statewide leash law. A dog running at large without a collar and rabies tag, or unvaccinated, may be impounded by officers; cities regulate running at large.
