Please check with all rescue groups in your area, even if they aren't for boston terrier , or are breed specific I.e. a sheltie rescue ect. Sometimes they do take in other dogs. Also this will help to get the word out. I would contact any trainers, kennels, and dog daycares too. I manage a dog daycare and we will post flyers and announce it on fb when someone notifies us of a lost dog . We have had several brought to us too!
