Contact the local shelters (both the city and county) and local veterinarians and give them a description of the pet and your contact information to see if anyone has found or brought in your pet.
Create a flyer with a picture of your pet for the shelters and veterinarians to display and also post them around your neighborhood.
Daily check the want ads/lost & found section of the local paper.
Take frequent walks or drives around your neighborhood (maybe enlist a team of others to help search).
