🪪 Do I need a dog license, and how much does it cost in Chicago?
Every dog four months or older must be registered with the City Clerk, with proof of a current rabies vaccine: $5 a year (or $15 for three years) if sterilized, $50 a year if not, with discounts for senior owners. Registration is also needed to use Park District dog-friendly areas.
🔊 What counts as a barking dog violation in Chicago?
It is against the law for an animal to make continuous excessive noise. Complaints go to Animal Care and Control through 311, which usually starts with a letter to the owner.

What Illinois state law adds
Dog licenses
Illinois has no statewide dog licensing requirement — counties and cities set their own. Most require a licence with proof of rabies vaccination, so check with your local animal services or clerk.
Under the Illinois Animal Control Act a dog found running at large may be impounded, the owner pays a $25 public safety fine, and a dog caught a second time must be sterilized. Hunting dogs and dogs in dog parks are exempt.
