When I was a youth, my dad would take in a stray dog, and later, drive to the other side of town and put the dog out.
They never did come back.
We used to live out in the country a few miles from a small town. People in town would bring their unwanted dogs out and dump them. We always kept a dog that turned up at our door.
One day one of our dogs disappeared. I went to all of the houses out our way. Finally I showed a picture of our dog to one of our neighbors. He hung his head and looked very sheepish.
He admitted that she had wandered to his house and thinking someone had dumped her on him, he took her back to town and dumped her there.
I finally found her but she wouldn’t stay home and finally got killed on the road. Sad story.
