Dangerous Dog Breeds Banned in Illinois: What Is Actually Illegal
October 31, 2026
Dangerous dog breeds banned in Illinois is a question with a split answer. The state does not ban any dog breed outright, but a handful of towns still do, and one wolf-dog category is illegal everywhere in the state.
That mix confuses a lot of owners. You can legally own a pit bull in Chicago, yet the same dog may be banned or heavily restricted a short drive away.
This article gives you the exact rules. You will see what state law says, which local ordinances exist, how mixed breeds are treated, and what to check before you move, rent, or buy insurance.
Important Note: This article is general information, not legal advice. Local ordinances change, so confirm the current text with your village or city clerk before you act.
Are Dangerous Dog Breeds Banned in Illinois?
No dog breed is banned statewide in Illinois. Illinois prohibits statewide breed-specific legislation, while some local governments still write their own rules.
The short version for you as an owner:
- Pit bulls, Rottweilers, German Shepherds and Dobermans are legal under state law.
- A few municipalities ban or restrict pit bull-type dogs, and Rottweilers in at least one village.
- Wolf-dog hybrids are the one category banned across the whole state.
For a national comparison, see our guide to banned dog breeds.
Does Illinois Have a Statewide Dog Breed Ban?
Illinois has no statewide ban on pet dog breeds, and the state does not keep a list of prohibited breeds. The Animal Control Act covers licensing, vaccination, and general control of dogs rather than specific breeds.
The one exception involves wolves. Illinois law classifies wolves as dangerous animals, and wolf-dog hybrids fall under the same ban.
Illinois does not treat a “low-content” hybrid differently from a “high-content” one. If an animal is sold or represented as having wolf ancestry, it can be treated as a wolf regardless of the actual percentage.
Can Cities and Counties in Illinois Ban Dog Breeds?
On paper, the answer is no. Illinois statute says a municipality may control and regulate dogs, cats and other animals as long as no regulation or ordinance is specific to breed.
In practice, some places still do it. PAWS Chicago explains that breeds are still banned in some Illinois towns because of a home rule provision in the state constitution.
Illinois is considered an untested home rule state on this point, meaning courts have not definitively resolved how far state law overrides local ordinances. That is why you will find old ordinances still on the books in some villages.
Key Insight: A town having an ordinance does not always mean it can be enforced. Morris, Illinois repealed its pit bull rules to comply with state law, and Chicago repealed its pit bull ban in 2016.
Cities and Counties in Illinois With Breed Bans or Restrictions
The list below comes from DogsBite.org, an advocacy group that supports breed laws, and from local-law summaries. Treat it as a starting point rather than a current legal roster, because villages repeal and amend ordinances without much notice.
| Municipality | Type of Rule | Breeds Named |
|---|---|---|
| Cahokia | Ban | Pit bulls |
| Golf | Ban | Pit bulls |
| Stone Park | Ban | Pit bulls |
| Barry | Ban | Pit bulls |
| Tampico | Ban | Pit bulls |
| Buffalo Grove | Restriction | Pit bulls and Rottweilers |
| Maywood | Restriction | Pit bulls |
| North Chicago | Restriction | Pit bulls |
| Prospect Heights | Declared “dangerous” | Pit bulls |
| Markham, Hanover | Declared “vicious” | Pit bulls |
Barry’s ordinance sets a fine of up to $750 for possessing a pit bull inside the city limits, according to a DuPage County law firm’s review. Local rules like this can differ sharply from your neighbor town’s, so check the municipal code where you live.
Cook County does not currently enforce breed-specific regulations, according to Animal of Things’ landlord and pet guide.
Dog Breeds Most Often Banned or Restricted in Illinois
Pit bull-type dogs dominate every Illinois list. Regulated pit bull types typically include American Pit Bull Terriers, American Staffordshire Terriers, Staffordshire Bull Terriers, and English Bull Terriers. You can read about how these dogs differ in our guide to types of pit bull dog breeds.
Rottweilers show up less often. Buffalo Grove is the clearest example, and it covers both breeds under one set of rules.
Private rules go wider. Landlords commonly restrict pit bull types, Rottweilers, Doberman Pinschers, German Shepherds, Akitas, Chows and wolf hybrids. Those are private lease choices, not government bans.
Dog Breed Bans vs. Breed Restrictions in Illinois
A ban means you cannot keep the dog inside the town at all. A restriction lets you keep the dog if you meet specific conditions.
| Feature | Ban | Restriction |
|---|---|---|
| Can you own the dog? | No, within town limits | Yes, with conditions |
| Typical penalty | Fine, removal of the dog | Fine if conditions are not met |
| Example | Barry, Stone Park | Buffalo Grove, Maywood |
| Common conditions | Not applicable | Permit, enclosure, signage, insurance |
Buffalo Grove requires a special enclosure and warning signs. Hanover requires a special license with $100,000 insurance coverage, and Maywood bars pit bull permits within 1,500 feet of schools, parks and similar facilities.
A third category sits in between. Prospect Heights does not ban pit bulls, but its ordinance declares them dangerous regardless of how the individual dog behaves.
How Illinois Defines a Dangerous Dog (Behavior, Not Breed)
State law looks at what a dog does. The Animal Control Act says vicious dogs “shall not be classified in a manner that is specific to breed,” as PAWS Chicago quotes it.
That means a Labrador that attacks someone can be declared dangerous, while a calm Rottweiler cannot be declared dangerous on breed alone. The legal process runs through a hearing and a finding based on conduct.
Our guide to the dangerous dog declaration in Illinois walks through the process step by step, including what owners can do after a declaration.
The state’s anti-breed language is older than its broader rule. According to a 2026 state-by-state review, Illinois added its clause covering all dog rules in Public Act 93-548, effective August 19, 2003, while the ban on calling a dog vicious because of breed is older.
How Breed Bans in Illinois Treat Mixed-Breed Dogs
Local bans usually cover mixes too. Barry’s ordinance defines a pit bull as any bull terrier breed, Staffordshire bull terrier, American pit bull terrier, American Staffordshire terrier, or any dog mixed with those breeds.
Prospect Heights uses similar language. Its ordinance covers any mixed breed dog that contains one of those breeds in its ancestry and is identifiable as partially that breed.
The word “identifiable” matters. Visual breed identification is unreliable, so a mix can be challenged when the evidence for its ancestry is thin.
Pro Tip: Keep your vet records, adoption papers and any DNA test results together. If an animal control officer questions your dog’s breed, documents carry more weight than opinions about its looks.
Exemptions and Grandfathered Dogs Under Illinois Breed Rules
Illinois has no statewide grandfather clause, because the state has no breed ban to grandfather dogs into. Any exemption you get comes from the local ordinance itself.
Some local codes work through permits instead. Maywood and Buffalo Grove, for example, set permit and enclosure conditions that existing owners must meet rather than allowing a blanket exemption.
If your town’s code mentions registration deadlines or “existing dogs,” ask the clerk in writing how it applies to your dog. Get the answer on paper before you assume your dog is covered.
Breed Restrictions by Landlords, HOAs, Insurers and Military Housing in Illinois
Private rules are the biggest day-to-day barrier. Illinois has no statewide breed preemption for landlords, so a private lease can lawfully exclude certain breeds.
Service animals and emotional support animals are different. Breed restrictions do not apply to either under federal and Illinois housing rules.
Insurers follow different law. According to the same 2026 review, 215 ILCS 5/143.10e took effect December 9, 2023, and bars refusal, cancellation or rate increases based solely on breed.
Housing developments set their own policies too. Private communities and HOAs can ban breeds even when the city allows them, so read your covenants before you buy. Military housing is set by each installation, and you should ask the base housing office for its current breed policy before moving in.
- Landlords: Can restrict breeds in leases, usually citing insurer requirements.
- HOAs: Can restrict breeds through covenants.
- Home insurers: Cannot act on breed alone under the 2023 rule.
- Military housing: Varies by installation.
Moving to Illinois With a Restricted Dog Breed
Start with the town, not the state. A breed allowed in one Illinois town may be banned in the next community over, so check the municipal code before you sign a lease or contract.
Follow this sequence before you move:
- Search the municipal code of your target town for “pit bull,” “vicious,” or “dangerous dog.”
- Call the village clerk or animal control and ask for the current rule in writing.
- Confirm lease, HOA and insurance terms for your dog’s breed.
- Review the state’s import rules in our guide to pet import laws in Illinois.
- Register and license your dog once you arrive.
- Licensing is a state-level standard, not a breed issue. All dog owners need a license showing the dog is identified and vaccinated against rabies.
- If you are comparing dogs before a move, see our list of popular dog breeds in Illinois.
- Can You Challenge a Local Breed Ban in Illinois?
- You can, but it is not simple. The state’s anti-breed language gives you an argument, while the home rule question leaves the outcome uncertain.
- Courts have also upheld local breed rules before. The Illinois Municipal League notes that a case called Vanater found a village had shown pit bull terriers were proper subjects of its police power, as described in its legal Q&A on breed-specific regulations.
- Your practical options are:
- Ask the town to repeal or amend the ordinance, as Morris did.
- Challenge a breed identification if your dog is a mix.
- Contest a “dangerous” or “vicious” label at the hearing stage.
- Talk to a local attorney who handles animal law before paying a fine or surrendering a dog.
- Recent Changes to Dog Breed Ban Laws in Illinois
- The trend in Illinois points away from breed bans. Chicago repealed its pit bull ban in 2016, and Morris repealed its ordinance to align with state law.
- Insurance rules changed most recently. Illinois’ 2023 insurance law blocks refusals, cancellations and rate increases based solely on breed, as noted above.
- Bills continue to appear. A reported Illinois House Bill 1603 would stop landlords from refusing to rent or imposing conditions based solely on dog breed in buildings with more than three units, according to this NewsBreak summary. Check the Illinois General Assembly site for its current status, since I could not confirm whether it became law.
- Older proposals went the other way. A past bill, HB 4213, would have let municipalities ban or restrict specific breeds, according to an advocacy action alert. Illinois law has continued to prohibit breed-specific rules at the state level.
- The bottom line for you: the state will not label your dog dangerous because of its breed, but your town, landlord or HOA might still limit it. Check all three before you commit to a home.
