For the municipal ordinance text see the city code; for local enforcement contact see the Animal Control office municipal code[1] and the city Animal Control information Animal Control[2].

Pet Licensing and Registration

Most residents must license dogs (and in some localities other pets) with the City Clerk or licensing office. Licenses typically require proof of current rabies vaccination and owner contact information. Renewal schedules and acceptable proof are described by the licensing office; fees and exact forms are published by the city or clerk when available.

  • Bring proof of rabies vaccination when applying.
  • Renew annually or per the schedule set by the City Clerk.
  • Pay applicable license fees; check the clerk for current amounts.
Licenses help reunite lost pets and confirm vaccination status.

Leash, Control and Nuisance Rules

Animals in public places are generally required to be under effective control. Leash rules, off-leash area designations and prohibitions on dangerous or unattended animals are set out in the municipal ordinances and enforced by animal-control officers and police as needed.

  • Keep dogs on a leash where required by ordinance.
  • Respond promptly to official warnings or notices to avoid escalation.
  • Report strays, bites or aggressive behavior to Animal Control.

Spay/Neuter and Public-Health Measures

The city may promote or require spay/neuter for certain animals through public-health programs or bylaw provisions. Where the municipality issues a specific spay/neuter requirement, the ordinance or public-health notice will describe exemptions and timelines.

  • Ask the Health Department about low-cost spay/neuter programs.
  • Check for exemptions such as medical necessity or breeder permits if allowed.
