okay- for what help this- we had a lab at large here. What we did was put food at every day at a certain time. If we even saw the dog at a distance, we didnt make eye contact. It took about a week but finally she came to my husband. He slipped a lead on her, talked in a friendly calm voice, and she didnt fight him. We brought her in the garage, and put down food. Then called our warden.
The dog had gotten lost on a hunting trip. The owner tried to give us 200 dollars in reward- we told them to give it to the shelter. We heard later he did.
