Your dog is required by law to be licensed in the State of Michigan by the age of 4 months. Proof of rabies vaccination must be shown to purchase this annual license. Typically, a license can be purchased at your township hall or government building prior to March 1st. After March 1st the license must be purchased at the Kalamazoo County Animal Services office.
A spay/neutered dog license is somewhat less expensive than a license for a non-neutered dog.
