I hope they've contacted all the area shelters, even ones that aren't close by to see if Sabbath was turned in, or picked up by ACO. Many shelters will euthanize if owners don't show up in a set number of days. It varies from shelter to shelter. They should go to shelters and insist on seeing all the dogs. My long gone RB girl Boots took off some years ago, and ended up at the shelter, but it was so hard to describe her, I went in and brought a photo. She'd been there all week dining on chicken! And I had called them numerous times too! Also they should contact all the vets in the area in case he was injured, and brought to a clinic. Posters everywhere as well as an ad in the newspapers. Dogs can travel a great distance when they aren't familiar with their surroundings. Sending prayers they find him soon.
