All dogs in the town are required to be licensed per state and county laws.  A dog license is $5 for spayed/neutered.  $10 for all others. Make the check payable to Town of Merrimac.  Include your rabies vaccinations certificate and a self-addressed return envelope. Dog license fees are collected every tax collection period and are considered late after April 1 for that license year. A $5 late fee is assessed for renewal licenses after April 1. If you are adopting a dog from the Sauk County Humane Society, they are authorized to license your dog, but only at adoption. Renewal licensing is still through the town.
