The primary objective of WCRAS is to ensure the safety of our community from issues related to domestic animals. Dangerous or vicious dogs can pose a serious threat to the well-being of citizens in Washoe County. The increasing number of unprovoked dog attacks on children, adults, and other domestic animals is a major concern, and WCRAS takes such cases seriously. To enhance public safety, regulating dogs that pose a threat within our community is imperative. WCRAS provides various services to address problems and regulate dogs exhibiting dangerous or vicious behavior, including:

  • Responding to and investigating reports of aggressive dogs
  • Investigating animal bites
  • Addressing stray dog complaints
  • Verifying compliance with mandatory rabies vaccination and dog licensing requirements
  • Assisting victims in petitioning to determine an offending dog as Dangerous or Vicious, thereby obtaining requirements and restrictions associated with keeping such a dog WCC 55.750.
