What the dog doin!?

You're walking home from work, after being allowed to leave early, when you see your dog trotting by itself up the street. Your dog that you thought was currently safe at home. And what's more, your dog seems to have done this before. People recognize it, and it even seems to have its own money?! What in the world is your dog doing? I had this weird thought and wanted to make it into a scenario. It's probably the most bizarre one I've ever made. Enjoy!
