Dog licensing and rabies rules in Kansas City and St. Louis
Missouri's two big cities both want proof of vaccination before they register a dog. Rules in other towns and counties vary, so treat this as a starting point.

Side by side

Kansas City details
The City of Kansas City, Missouri animal licensing page cites Chapter 14 of the city's Code of Ordinances. It says not every veterinarian can process a license, so confirm with your clinic before you go.
St. Louis details
The City of St. Louis pet registration page says that failing to keep vaccination and registration current can result in a ticket and a fine. Visiting pets need proof of current immunization, and they need city registration only if they stay longer than 30 days.
What if you live elsewhere in Missouri
Counties, suburbs and small towns write their own animal codes, including leash, nuisance and licensing rules. Call the city clerk or county animal control before the dog arrives and ask for the ordinance by name.
