Frequently Asked Questions

Is there a leash-length requirement?
The code defines a leash as a cord, rope, strap, or chain fastened to the collar and strong enough to control the animal, but sets no specific length outside the vicious-dog enclosure rule.
Does this apply inside Springfield city limits?
No: county animal control governs unincorporated Sangamon County; Springfield and the other incorporated municipalities enforce their own at-large ordinances.
