The Chicago City Clerk requires all dogs four months and older be registered with the City of Chicago.
[Registration costs $5 annually for spayed or neutered animals and $50 for dogs that haven’t been sterilized.](http://www.chicityclerk.com/dogs )
If your dog is currently not registered, please do so as soon as possible in order to avoid a citation.
Per city ordinance, police and other city officials can ask to see the license for a dog on the public way, and if it can’t be produced, the official can immediately issue a citation ranging from $30 to $200. The fines will be repeated daily until a dog license is purchased.
With certification of rabies vaccination, registration can be completed by clicking here. Call the Chicago City Clerk at 312-744-6770 with questions or to check registration status.
