We live in Trailwood Village and our little dog got out of our yard. He is not chipped, no collar, and and is totally deaf. He is white with brown spots. Short hair. Floppy ears. Not sure what I should do. Never lost a pet before. As of 5pm he has been gone about 2 hours. We have been looking for him the entire time.
