Craigslist is NOT the place to buy a puppy. There is a probable scam happening on Craigslist right now regarding the sale of Basenji puppies. It is going on across the country, some ads have been removed, but new ones go up; currently there are ads in CA, CO, NM, OH, and FL. All ads have various titles, pictures, and reply-to email address, yet every reply I've gotten back is from: Suzan Lake <firstname.lastname@example.org and she sends the same group of 15 pictures.
She is giving away the pups, but she wants you to send $$ for airflight for them from Philadelphia. I smell scam, and there can't possibly be that number of litters available right now!
