Animal Control Officer (ACO)

The ACO is a non-sworn member of the police department whose duties vary and can include:

  • Sick or injured wildlife, stray domestic animals, and trapping, relocation, and abatement of wild animals. 
  • City ordinance enforcement like parking, abandoned vehicles, and illegal burning.
  • Assists in traffic control duties, vehicle and building lockouts, fingerprinting, and child safety seat inspections. The ACO is available to address schools, children’s groups, homeowners’ associations, etc. regarding humane education and dog bite prevention for children.

Animal Shelter (Warrenville PD)

The Police Department operates an animal shelter that is used to house stray domestic animals found running at large within the city limits. This shelter is licensed annually through the Illinois Department of Agriculture.  Animals found wearing a collar, tags, or having a micro-chip are housed for seven days. Animals found without a collar, tags, or micro-chip are housed for five days.  These holding periods are regulated by State law.  Any animal that is not reclaimed is sent to a local humane society, rescue group, or the DuPage County Animal Services for disposition.

Disaster Planning for Your Pet

Pets depend on their caregivers to provide for their safety and well-being, so having a disaster plan for them is important. When you create a disaster plan for your family, include your pets within it.  Disaster Plan suggestions (PDF)

Dog Licensing
City dog license(s) and tags are required for all dogs residing within city limits. Dog licenses are valid for one calendar year, and renew annually (January). Dog licenses may be purchased at City Hall or the Police Department during regular business hours.  Learn more about the dog licensing ordinance at this link.

Micro-chipping Your Dog

The Police Department will scan for micro-chipped pets, but does not insert them. Micro-chipping may be done by a veterinarian, or at DuPage County Animal Services.

Reclaiming an Animal 

Call the non-emergency Police Department telephone number (630) 393-2131 during regular business hours, and ask to speak with a Community Service Officer.

Reporting Found Animals

If you find or see what appears to be a lost pet or injured animal, please dial 9-1-1.  All found animals are kept in the animal shelter and are scanned for a micro-chip.  Pet owners  are encouraged to call the Police Department to see if their lost animal has been found.  

Reporting Lost Animals

Owners should contact the non-emergency number of the Police Department (630-393-2131) immediately to make a lost animal report. This report may be taken over the telephone or given in person. The owner is asked to provide a full description of the lost animal, location and time the animal went missing, and/or a photo. Pet owners should also notify surrounding police departments and county animal control agencies. Owners should never assume their pet will return home on its own.

All dogs and cats should wear a collar with a current rabies tag and a city dog tag (cats excluded) and should be micro-chipped. Micro-chips are available at veterinarians’ offices, county animal control agencies, and local humane societies. Unlike collars, micro-chips are a permanent form of identification.

*Dog owners may also choose to report lost pets to the following internet sites: Lost Dogs Illinois, Find my Fido, and Find my Pet. These sites are not affiliated with the Police Department nor the City of Warrenville, who do not report to them.*
