Health department reviews 'potentially dangerous' dog designation process, enforcement and rabies clinic planning

McHenry County Department of Health staff briefed the Board of Health on Nov. 18 about the county’s process for designating dogs as "potentially dangerous," enforcement steps if requirements are not met, and plans for spring rabies vaccination clinics.

Staff said the department recently completed its first case in which a dog reached the 24-month review point and was removed from the potentially dangerous list after the owner met requirements. The department emphasized the designation’s oversight requirements — registration, up-to-date vaccinations, adult caregiver, leashing and muzzling off the owner’s property — and that some requirements are recommendations rather than legally enforceable once a dog has been removed from the listing.

Why it matters: Changes to how potentially dangerous and dangerous dogs are monitored affect public safety, animal welfare and enforcement workload for public-health and law-enforcement partners.

Details discussed - 24-month review and removal: Staff said owners can request a review; if the dog has no violations during the period, it can be removed. The department sends written notification to owners when the 24-month period ends.

- Ongoing requirements during designation: While designated as potentially dangerous, owners must keep dogs vaccinated and registered, provide an adult caregiver, and keep the dog leashed and muzzled off the property. Spay/neuter is not required for a potentially dangerous designation (it is required for a dangerous dog).

- Enforcement steps: If owners fail to meet requirements for a potentially dangerous dog, staff said the department may move to a dangerous-dog designation, which can include impoundment. Impoundment actions require either voluntary surrender or a warrant and may include fines and other court processes.

- Rabies clinics and registration tools: Staff said spring rabies clinics are being planned in areas such as Harvard and near Johnsburg/Richmond, and the department is evaluating data-entry tools with a vendor called Chameleon (and a program called Knowledge Rocket) to streamline microchip and vaccination registration uploads from Excel.

- Animals from court case: The department is holding 16 animals from a July criminal court case; staff said they expect resolution of that custody matter in the near term.

Board questions focused on who enforces muzzling and whether written notices are sent at removal and how appeals proceed (appeals generally go to circuit court and are rare because of expense). Staff noted they notify law enforcement about animals with a dangerous or potentially dangerous designation.

What’s next: Staff will finalize spring rabies clinic sites and dates, continue data-entry testing with the vendor and follow up on the 16 animals held from the criminal case.
