Instructions for Dog Owners

  1. Make sure your dog is currently vaccinated for rabies. Your veterinarian will give you a "Certificate of Rabies Vaccination" showing the expiration date for the vaccination.
  2. Complete the Dog License Application, available to download and print here, or online via the Cass County Animal Control website. Use a separate application for each dog you own.
  3. Mail the Certificate of Rabies Vaccination and the completed Dog License Application, along with a check or money order for the proper license fee amount and Proof of Spaying or Neutering to the Cass County Treasurer at 120 North Broadway Suite 113, Cassopolis, MI 49031.
  4. Upon receipt of required documents and fee, your license and tag will be mailed to you. Your Certificate of Vaccination will be returned to you. If you don't receive these items within 45 days, please contact the Cass County Treasurer at 269-445-4468.
  5. The tag should be worn by your dog. That is your dog's "ticket home" if the dog gets lost.
