Modifies the offense of keeping a dangerous dog
HB 1423 revises Missouri’s dangerous-dog law by repealing and reenacting section 578.024, which defines the offense of keeping a dangerous dog and sets the penalties for owners or possessors of dogs that bite or attack without provocation. The bill keeps the basic framework that a dog becomes “dangerous” after an unprovoked bite, including repeated bites, but clarifies and updates the penalty structure for incidents involving serious injury or death. It distinguishes between an infraction, misdemeanors, and more serious felony penalties depending on whether the attack causes serious injury or death to a person, domestic animal, or livestock, and whether there has been a prior serious attack.
The bill also strengthens the seizure and destruction process for dogs involved in qualifying attacks. A dog that has previously bitten, or a dog that causes serious injury or death in a qualifying attack, must be seized immediately by animal control or the county sheriff, impounded for ten business days after written notice, and then destroyed unless the owner successfully appeals. The bill provides a circuit-court appeal process, requires a disposition hearing within 30 days, and allows the court to assign the costs of keeping and caring for the dog during the appeal to the owner or possessor.
HB 1423 further limits owner liability and criminal exposure when the person bitten was engaged in criminal activity at the time of the attack, with an express exception that ordinary trespass is not treated as criminal activity in some circumstances. It also preserves the court’s authority to order payment of medical bills for injured people and replacement costs for domestic animals or livestock killed in an attack. In addition, the bill states that a person, property owner, or livestock owner may kill a dog that behaves aggressively in a way that reasonably places them in fear for life or the life of others or animals.
The overall sentiment reflected by the bill text and available context is generally protective of public safety, livestock, and property owners, with an emphasis on giving authorities clearer tools to respond to dangerous dogs. Because there are no committee transcripts or recorded votes provided, there is no documented floor or committee debate to show broader support or opposition. The main policy tension inherent in the bill is between stronger animal-control enforcement and the rights of dog owners to contest seizure and destruction, especially where attacks involve disputed circumstances or where the injured person was engaged in criminal conduct.
HB 1423 would replace Missouri’s existing dangerous-dog statute, section 578.024, with a revised version that redefines and reorganizes the offense, penalties, and enforcement procedures. It affects dog owners and possessors, animal control authorities, county sheriffs, circuit courts, and victims of dog attacks, including people, domestic animals, and livestock. The bill would also interact with related statutes governing civil liability and defenses for dog attacks, while creating a more detailed appeal and impoundment process and clarifying when an owner is not liable if the victim was engaged in criminal activity.
The available materials suggest a generally favorable or at least safety-oriented posture toward the bill, since it is framed as a modification of the dangerous-dog offense rather than a major policy overhaul. The bill’s structure indicates concern for public protection, livestock losses, and clear enforcement authority. However, no committee testimony or vote history is available, so there is no direct evidence of partisan or stakeholder sentiment beyond the statutory changes themselves.
The most likely points of contention are the bill’s expanded or clarified penalties, the mandatory seizure and destruction provisions, and the scope of the criminal-activity exception. Dog owners may object to the immediate impoundment and destruction process, while animal welfare advocates may object to authorizing destruction after certain attacks. On the other side, property owners, livestock owners, and public-safety advocates may support the bill’s stronger remedies and cost-shifting provisions. The exception for victims engaged in criminal activity could also be disputed, particularly where it limits liability and defenses, though the bill narrows that exception by excluding simple trespass in some cases.
