  • Rule: Missouri's rabies law is RSMo Chapter 322 (Protection Against Rabies). Section 322.090 empowers county commissions to adopt rules on licensing, impounding, confinement and rabies control and requires them to operate a county dog pound (may contract with cities); 322.030 requires the owner of a dog exposed to a rabid animal to have it treated by a licensed veterinarian or destroyed. Pet vaccination requirements are therefore set by county and city ordinance.
