Get a fly to every neighbor and knock on their door and call your dog's name. Ask him to look in their buildings under desks and under porches. Contact every shelter and go and visit those shelters. Notify every veterinarian and rescue that you possibly can. Register your dog as lost with the shelters and make sure they have a photo. As the police to keep an eye out for your dog. They are awesome about doing that. If you have any other pets take them securely with you and walk all around. They may smell one another. Many prayers
Please file a lost report with MADACC and notify the Humane Society, your neighbors, all the vets in your area, your mail carriers & your local police. Also check MADACC's website https://madacc.org/
