My neighbor’s dog barks and barks. What can I do?
- Barking dog complaints are difficult to follow-up. Our officers are dispatched for barking complaints, but it is common that the dog is quiet when the officer arrives. The officer must hear and document the barking; the officer may issue a notice of public complaint to the dog owner.
- The law does not require complete silence for dogs. Barking is how dogs communicate. However, the ordinance does prohibit barking, whining or howling for longer than 15 minutes continuously, two hours intermittently, and any noise between 10:00 pm and 6:00 am.
A cat is hanging around my house and I don’t want it. What can I do?
- MCDH Veterinary Division will pick up a stray cat IF you have it contained. We do not place traps for cats. Live traps can be rented or purchased at local stores. However, we do not encourage trapping for cats as it is too easy to trap raccoons, opossums, or skunks by mistake. A permit from the Illinois Department of Natural Resources is required for trapping nuisance wildlife.
- IF the cat has the tip of its left ear gone, it is part of a managed feral cat colony. It has no owner, and technically cannot be a stray.
- IF you have been feeding and/or sheltering the cat for longer than seven days, legally you are the owner of the cat.
Are you a no-kill shelter?
- No, because we handle biting animals and animals that have killed other animals that, in the interests of public health and safety, cannot be safely re-homed.
- We are a low-kill facility. Every adoptable animal is placed in a new home. We do not euthanize for time or space.
Do you have volunteer opportunities?
- YES! MCDH Veterinary Division is always looking for talented, energetic volunteers. You must be at least 18 years of age to volunteer.
- Volunteers help with socializing animals, adoption counseling, cage and kennel cleaning, and office work.
- Thanks to our volunteers, more pets have the opportunity to find new homes and live happier lives.
Do you have educational programs?
- YES! MCDH Veterinary Division offers informational presentations for local businesses, schools, community organizations and other groups.
- Program topics include bite prevention and responsible pet ownership. Call 815-334-4946 to schedule a speaker.
Do you pick up dead animals?
- Deceased dogs and cats are retrieved by MCDH Veterinary Division, checked against the lost reports, and scanned for a microchip in an effort to locate the owner. If a deceased wild animal caused a potential human exposure to rabies, it would also be retrieved for rabies testing.
- If the dead animal is a bird and you are concerned about West Nile Virus, contact the Environmental Health Division at 815-334-4585 for assistance.
I have a concern regarding a kennel or animal shelter, who should I contact?
