The definitions
A plain English glossary of Southern dog law
One bite rule, scienter, preemption, impoundment, strike all amendment: the words the codes and the briefs use, defined in plain English.
The words below are the working vocabulary of Southern dog law: the terms the codes, the ordinances and the briefs use, defined in plain English and in the Southern context. Each entry is short enough to memorize and exact enough to argue with, and the ones that have a home page on this site carry the link to it. When a statute uses one of these words differently than this glossary does, the statute wins; the desk updates the entry and dates it.
The words the courts use
One bite rule
The common law rule that an owner answers for a dog once the owner knew, or should be taken as knowing, that the dog was dangerous. Mississippi's version is case law from 1973, and it is read in full at the one bite rule page, nickname corrected there.
Dangerous propensity
A disposition in the dog to do the kind of harm that happened: not a breed, not a look, a record of acts. The element most bite cases are actually fought over.
Scienter
Lawyer's Latin for knowing. The scienter action is the claim that sues an owner on what the owner knew about the animal, which is the ancestor of the one bite rule.
Strict liability
Liability without fault and without prior knowledge: the first bite is enough, and the dog's history is beside the point. No Southern state read so far applies it flatly to dogs; the class matters for reading maps that say some state is strict.
Negligence
The failure to use the care an ordinary owner would use in the same situation. Where no dog statute speaks, Mississippi claims about dogs run on the ordinary negligence questions: duty, breach, cause.
The words of city hall
Preemption
A doctrine and a statute's effect: when a state legislature occupies a field, city ordinances in that field give way. The pivot of the breed question, read state by state at preemption in the South.
Grandfather clause
A provision sparing old local rules from a new statute. Florida's breed preemption carried one for decades; the 2023 session removed it, and the city bans that leaned on it lost their prop.
Municipal ordinance
A law passed by a city council under its delegated power. In Mississippi, the leash rule, the fines, the barking hours and the dangerous dog process are all ordinance, not code; the sections behind that are read at impoundment and hearings.
Municipal police power
The grant that lets a city regulate for health and safety. Miss. Code Ann. section 21-19-9 is the animal half of it in Mississippi: regulate at large, impound, penalize, and go further than the state code.
Running at large
Off the owner's premises and not under control, in whatever words the local text uses. The oldest framing in dog law, older than the leash by a century, and still the load bearing phrase of most ordinances.
Impoundment
The taking up and holding of a dog by the authority the city or county designates. Fees, holding periods and disposition are set by the local text; the state's five day hold addresses the dog found at large without collar or tag.
Redemption period
The window in which an owner may reclaim an impounded dog, on the conditions the ordinance writes. Reading your own city's window before you need it is cheaper than reading it after.
Dangerous dog declaration
An official process that labels a dog dangerous or vicious and attaches conditions to keeping it. Mississippi has no state statute for it; the process exists only where a city wrote one.
Quarantine
The observation period imposed after a bite, aimed at rabies, set by health rules and the vaccination record. The collar tag and the certificate behind it are what shorten the uncertainty.
The words of the pipeline
Strike all amendment
A committee move that keeps a bill's number and replaces every word under the title. The reason a bill story written at filing cannot be trusted at hearing, unpacked at strike all amendment.
Engrossed text
The version of a bill as amended and moving forward. When a summary and the engrossed text disagree, the engrossed text wins, always.
Codification
The printing of enacted law into the published code, with the section number everyone will cite from then on. The end of the pipeline and the start of the citation.
Limitation period
The deadline for filing a claim. For Mississippi personal injury actions the desk records three years, with the reserve that the section number joins the entry when the title is opened for it.
The one health term
Heartworm incidence
The share of tested dogs found infected, as reported by clinics and shelters to the triennial survey of the American Heartworm Society. A survey figure, not a census: it carries its publisher and its year, and it says nothing about a single yard. The Delta reading is at heartworm incidence data.
How an entry earns its place
Every entry above is written against a text this journal opened: a code section, a decision, an ordinance structure, a survey's own method page. Entries age, and when a statute moves, the entry moves with it and carries the date. The classes of rule named here each have a column in the comparison table, which is where the vocabulary meets the scoreboard.
