Full Breakdown
County Code § 205.032 bars owners from letting any animal run at large off their premises. In a residentially zoned district, dogs and other domesticated animals off-property must be on a leash no longer than 10 feet and under the owner's adequate control. Dangerous dogs face a stricter rule: a humane muzzle plus a leash capped at 4 feet. The Department of Public Health's Animal Control Division enforces the chapter, and hunting dogs, field-trial dogs, and dogs at County-designated off-leash parks are exempted.
Violations & Fines
Impound fees run $20 (1st offense) up to $100 for a 4th+ offense if the dog is registered/vaccinated, and $25 up to $100 if not (§ 205.240). Beyond impound fees, any Chapter 205 violation is a misdemeanor punishable by up to a $1,000 fine or up to 1 year in jail, with each day a separate offense (§ 205.250).
