Missouri dog law that every protection dog owner should read
Three state laws shape the legal risk of owning a powerful dog. Here is what each says, with links to the text.
1. Strict liability for unprovoked bites
Missouri's RSMo 273.036 makes an owner or possessor liable when a dog bites a person without provocation, as long as the person is on public property or lawfully on private property, including the owner's own. The statute calls this strict liability, which means it applies even if the dog never showed aggression before.
The same section covers property and livestock damage the dog directly causes, lowers damages by the injured person's own share of fault, and adds a fine of up to $1,000 on top of other remedies.
2. The repeat-bite offense
RSMo 578.024 addresses an owner or possessor whose dog previously bit a person or domestic animal without provocation and then bites someone again. The base offense is a class B misdemeanor, and it rises to a class A misdemeanor, then to felony levels, when injury is serious or fatal.
The statute also allows animal control or the sheriff to seize the dog, hold it for ten business days after written notice to the owner and then destroy it, with a right of appeal to circuit court. An exception covers attacks on someone engaged in criminal activity at the time.
3. When another person may defend against your dog
RSMo 273.033 gives a person a complete defense against criminal charges or civil liability if they injure or kill a dog while reasonably fearing imminent harmful contact from it. After two complaints to the sheriff or animal control about a loose dog trespassing, a further trespass counts as prima facie evidence of that fear.
Practically, a protection dog that wanders is a danger to the dog as well as to the neighbors.
4. Rabies and the veterinarian
The Missouri health department's Missouri rabies manual chapter urges owners to vaccinate dogs and notes that rabies vaccination in Missouri may legally be performed only by a licensed veterinarian. City and county paperwork differs, so see the Kansas City and St. Louis page for two examples.
Insurance and landlords
Homeowners and renters policies often carry liability coverage, but insurers may ask about the dog or limit certain breeds. The NerdWallet overview of dog bites and homeowners coverage is a starting point. Ask your own agent, describe the dog accurately and keep the answer in writing.
Landlords and homeowner associations add their own limits, which no state statute overrides in your favor.
