OH SB185

Restructures Ohio's dangerous/vicious dog designation process by requiring court hearings based on probable cause before a dog can be officially designated, rather than allowing administrative designation by dog wardens with optional owner appeal

Creates new registration requirements for dangerous and vicious dogs with the county dog warden, including a $50 annual fee, proof of rabies vaccination, spay/neuter documentation, microchip identification, and posted warning signs at the owner's residence

Establishes three tiers of dog behavior violations: "nuisance dog acts" (chasing, threatening behavior), "dangerous dog acts" (causing non-serious injury to people or killing other animals), and "vicious dog acts" (killing or causing serious injury to people)

Imposes escalating criminal penalties for owners who fail to prevent their dogs from committing these acts, ranging from minor misdemeanors for nuisance violations up to third-degree felonies when dangerous/vicious dogs injure or kill people

Requires owners of dangerous and vicious dogs to confine them in locked enclosures with tops, use six-foot chain-link leashes when off premises, and obtain liability insurance of at least $100,000 if ordered by a court
