Animal Bite Investigations

Bites to humans and companion animals must be reported to the local police department or to the Cook County Sheriff's office for unincorporated areas. A Cook County Bite Report will be completed by the law enforcement agency and forwarded to the Animal and Rabies Control office. Compliance for bite protocols are enforced by the Department of Animal and Rabies Control.  

If a bite (scratch) occurs:

  • Contact your local police department and inform the police that your pet bit someone.

  • The biting animal must be examined by a veterinarian immediately and the veterinarian must be informed that the animal was involved in a bite incident.

  • The biting animal must not be killed, sold, moved or otherwise disposed of.

  • The biting animal must not receive a rabies shot until the last day of the observation period.
