What is a "Dangerous Dog"?

Local rules allow a municipal designation when a dog poses a risk to public safety through biting, aggressive attacks, or repeated threats. Designation procedures and specific definitions are set in the city code and related enforcement rules; exact statutory language and thresholds should be read on the official code pages linked below.

Owner Duties After Designation

  • Secure housing or enclosure meeting code requirements.
  • Maintain current licensing and identification as required by local ordinance.
  • Keep records of veterinary care and proof of vaccinations if requested by enforcement.
  • Follow any signage, muzzling, leash, or supervision conditions imposed by the authority.
  • Pay any fines, impound fees, or compliance-related costs assessed by the enforcing office.
Owner compliance typically reduces the risk of seizure or further enforcement action.

Penalties & Enforcement

Specific monetary fines and precise escalation amounts are not specified on the city code summary pages linked in Help and Support / Resources below; consult those official pages for exact figures and section citations.
