Dangerous Dog Evaluations in McHenry, Lake & Cook County: What You Need to Know
Dangerous Dog Evaluations in McHenry, Lake & Cook County: What You Need to Know
If your dog has been involved in a bite or aggressive incident, you may get a letter from McHenry County Animal Control, Lake County Animal Control, or Cook County Animal Control about a dangerous dog evaluation.
This process decides if your dog is labeled potentially dangerous, dangerous, or vicious under Illinois law. Here’s what to expect.
What Is a Dangerous Dog Evaluation?
A dangerous dog evaluation is a behavioral assessment. An experienced behavioral specialist observes your dog, your home, and your property.
The goal is to understand what happened, assess risk, and create a management and behavioral plan to keep everyone safe. It is NOT a bite test or anything unethical.
Who Does the Evaluation in McHenry, Lake & Cook County?
Each county follows the Illinois Animal Control Act but enforces it locally:
McHenry County Animal Control: Investigates incidents and can require a behavioral evaluation + management plan.
Lake County Animal Control: Reviews reports and determines if a "potentially dangerous, dangerous, or vicious" designation applies.
Cook County Animal Control: Enforces the Cook County Animal Ordinance, which includes evaluations, registration, and requirements.
After the evaluation, the specialist submits a report and recommendations to the county.
What Are The Possible Outcomes?
Based on the evaluation and incident, the county may classify your dog as:
Potentially Dangerous - 1 incident. Requires registration, enclosure, and precautions
Dangerous - Severe injury or multiple incidents. Requires microchip, insurance, muzzle, secure enclosure
Vicious - Unprovoked attack causing serious injury/death. Strictest requirements
Can You Appeal It?
Yes. If your dog receives a designation in McHenry, Lake, or Cook County, you have the right to request a hearing/appeal with the county. There are deadlines, so respond to all notices right away.
How To Prepare For The Evaluation

Secure your home/property - fences, gates, signage
