McHenry County Animal Control and Adoption Center (MCAC) is the location of the McHenry County Department of Health Veterinary Division. MCDH Veterinary Division's  Animal Control Officers provide code enforcement of Animal Control Article of the McHenry County Public Health Ordinance. Effective animal control activities protect people and pets. Community outreach services include education on dog bite prevention, humane care for animals, and pet adoptions. MCAC houses stray animals for the county, and provides dog licensing.

Animal Control Officers respond to citizen complaints about violations of the Public Health Ordinance. Each year, MCDH Veterinary Division conducts thousands of investigations, ranging from minor code violations to felony animal cruelty. When possible, voluntary compliance is sought through educating owners about animal care responsibilities. If compliance is not obtained, MCDH Veterinary Division officers have the ability to issue tickets for Ordinance violations. Officers also pick up stray, sick and injured animals.

If you are aware of a situation where public health or safety is in jeopardy, or an animal is the subject of neglect or cruelty, you are urged to contact MCDH Veterinary Division at (815) 459-6222 to report what you have seen, heard, or experienced. An Animal Control Officer will be dispatched to investigate and follow up on the situation.
