Lost Dog: Niko, Brown Coat, Wichita Falls

1 years old, approximately 50 lbs but may have lost weight now. He has a brown coat with a little black on his back and tail. White chest, and a little diamond pattern on his forehead. He's neutered and wearing his camouflage/ hunting print collar with name ID tag. He is chipped also. Niko is very sweet but very skittish and afraid of vehicles. He maybe roaming around during the night. We are new to Wichita, were only here 4 days before he got lost. Any help, tips of seeing him around is greatly appreciated.
