Haha...I had a dog at church follow me today. I walked out of church (I'm the music director there), and there was this little Scotty dog wearing a dog sweater. I looked at him and he at me, so I walked up to him thinking he might run. Instead he let me pet him. I just stayed with him for a while and then a boy on a bicycle came riding into our parking lot. I called him over, and sure enough, it was his dog. Amazing, isn't it!
We also have across the street neighbors who were visited by someone who owned a pit bull. The dog would constantly get loose. I walked out of my house one day and there he was, in my driveway. I thought, oh no....a pit bull. But he came up to me and I scratched him under his neck. He loved it. He would constantly get loose and come over to the house. I think the owner got rid of him, however, because I haven't seem him in a long time. You should always love and take care of your animal friends.
