NOTHING IS FREE.
Go on Craigslist and if you are looking for a "free" dog, you will be asked to pay a 200 dollar rehoming fee.
Are you the same person that clicks on any flashing add that says "Free* Laptop, Free*Computer, Free*Vacation, Free* ANYTHING"? You cheap ###s, go to a shelter, drop 100 bucks, get a dog. Of course, I'm guessing you will get it home, realize that you can't just put a rotty in a bag and take it with you and then cry, after which you will let it out on the street.
On second thought, get a plant- not a dog.
