Dangerous Dogs: Determination

One of WCRAS’ primary goals is to help ensure the safety of our community from domestic animal related problems. Dangerous dogs can pose a serious threat to the safety and welfare of citizens in Washoe County. The number of unprovoked dog attacks on children, adults and other domestic animals is of great concern and WCRAS takes these cases very seriously.  In order to adequately increase public safety, it is necessary for regulation of dogs that pose a threat within our community.  WCRAS provides services to mitigate problems and to regulate dogs exhibiting dangerous behavior including:

  • Responding to and investigating reports of aggressive dogs
  • Investigating animal bites

  • Addressing stray dog complaints

  • Verifying compliance of mandatory rabies vaccination and dog licensing requirements

  • Petitioning or assisting the victim in petitioning to determine an offending dog as Dangerous, thereby obtaining requirements and restrictions associated with the keeping of a Dangerous Dog.

What Can You Do?

If you or your animal has been attacked by a dog, or you are an authorized representative for someone who has, you should seek medical attention if necessary and then call WCRAS to report the incident at 775-322-3647, 8 am - 10 pm daily or, for afterhours emergency, call 911. Animal Control Officers are here to assist you.

If the incident meets the criteria for a dangerous dog determination hearing, an Officer can assist you with making a request to file a complaint before an administrative hearing officer or a judge, and request the dog be determined dangerous. 

The purpose of the administrative hearing is to allow the victim as well as the owner of the dog in question to present evidence and testimony to the hearing officer or judge for consideration in the determination. The hearing officer or judge may make a determination that the dog is or is not a dangerous dog based upon evidence of the dog’s history or propensity to attack without provocation as outlined within WCC 55.750.

Dangerous Dog Determination Hearings are held at the Washoe County Administrative Complex at 1001 East Ninth Street, Reno, Nevada 89512. You can reach the Administrative Hearing Office at 775-328-2001 or you can request a hearing in person at 1001 East Ninth Street, Reno, NV 89512.

If a dog is determined dangerous by a Hearing Officer or Judge, an Animal Services Supervisor will make contact with the dog owner to explain requirements and restrictions under WCC 55.760 and WCC 55.770.
