Illinois law does not outright ban leaving your pet chained or tethered outside, but it imposes strict regulations designed to ensure humane treatment and protect animal welfare. Leaving a pet chained outside in violation of these regulations is illegal and can carry criminal penalties, especially for repeat offenders.
Key Legal Requirements for Tethering Pets in Illinois
Under the Illinois Humane Care for Animals Act (510 ILCS 70/3), dog owners must meet the following specific requirements when tethering a dog outdoors:
Basic Care Obligations
Every owner must provide:
Sufficient quality food and water
Adequate shelter and protection from the weather
Veterinary care when necessary
Humane care and treatment
Tethering Rules and Restrictions
Minimum Tether Length: The tether (lead) must be at least 10 feet long (rounded to the nearest whole foot).
Maximum Tether Weight: The tether must not exceed one-eighth of the dog’s body weight.
Prohibited Tether Types: Use of tow chains, log chains, and pinch, prong, or choke-type collars is banned.
Health Conditions: Dogs must not be tethered if they have a condition known to be worsened by tethering (e.g., joint or respiratory issues).
No Entanglement: The set-up must prevent entanglement with other tethered dogs.
Location Restrictions: Tethering cannot allow the dog to reach another person’s property, public walkways, or a road.
Shelter, Food, and Water: Dogs must always have access to shelter, food, and water when tethered.
Local Ordinance Examples
Some cities, such as Rockford and Galesburg, impose stricter limits—Rockford prohibits tethering dogs for more than 20 minutes between 10 p.m. and 7 a.m., and Galesburg limits outdoor tethering to six hours per 24-hour period.
Extreme Weather Conditions
It is illegal to leave pets chained outside during extreme heat, cold, or dangerous weather that may threaten their well-being. Owners must ensure dogs are not exposed to conditions that endanger their health or safety.

What Should Pet Owners Do?
Always provide your pet with shelter, food, and water when they are outside.
Use a proper harness and an appropriate, lightweight tether.
Avoid leaving pets outside during dangerous weather.
Supervise your pet when possible, or use alternatives like a fenced yard or outdoor pen.
Check local ordinances for stricter rules that may apply in your municipality.
Leaving your pet chained outside is not automatically illegal in Illinois, but strict rules apply. Owners must meet detailed care and tethering requirements; failure to do so is a crime and may result in penalties, loss of your pet, or even jail time. Always follow both state and local law to ensure your pet’s safety and well-being.
