Modifies the offense of keeping a dangerous dog

HB 3053 revises Missouri's law on "keeping a dangerous dog" by defining the offense as owning a dog that bites without provocation (once for an infraction) or bites again after a prior incident, or causes serious injury or death (escalating penalties). It requires animal control to seize and impound such dogs for 10 business days before destruction, with owners able to appeal to court within 30 days to contest the destruction. The bill exempts owners from liability and prevents dog destruction if the victim was committing a crime (excluding minor trespasses), and allows victims to seek compensation for medical costs or replacement of dead livestock. These changes aim to clarify penalties for dangerous dogs while providing due process for owners and compensation for victims.
