A few years ago, my wife saw a friendly, well-groomed dog running around in the street. The dog didn’t have any tags, so my wife invited the dog into our house and then she posted some “Dog Found” flyers around the neighborhood. The dog proceeded to drink our dog’s water, attempt to play with the cat, and run around in circles for a couple hours before finally being reunited with its owner. Our pets were happy to see their “houseguest” leave.
